用于管理停車(chē)場(chǎng)的方法包括以下步驟：確定停車(chē)場(chǎng)能夠被停放的機(jī)動(dòng)車(chē)占據(jù)的區(qū)域P，確定停放的機(jī)動(dòng)車(chē)當(dāng)前占用的停車(chē)場(chǎng)的面積K，以及確定 基于關(guān)系Z =（1-K / P）*

停車(chē)場(chǎng)設(shè)計(jì)成容納可停放在其中的多個(gè)機(jī)動(dòng)車(chē)輛。在這種情況下，沒(méi)有關(guān)于機(jī)動(dòng)車(chē)輛停放在停車(chē)場(chǎng)中的方式或順序的具體規(guī)定。因此，機(jī)動(dòng)車(chē)輛在停車(chē)場(chǎng)中的布置可以改變。 與有組織的停車(chē)場(chǎng)相反，在有組織的停車(chē)場(chǎng)中識(shí)別可能分別由機(jī)動(dòng)車(chē)占據(jù)的停車(chē)位，難以管理無(wú)組織的停車(chē)場(chǎng)。特別地，可能難以確定在給定時(shí)間可能另外停放在停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的數(shù)量。 發(fā)明內(nèi)容本發(fā)明的目的是提供一種用于管理停車(chē)場(chǎng)的技術(shù)，該技術(shù)被設(shè)計(jì)用于停放機(jī)動(dòng)車(chē)輛。 概要 停車(chē)場(chǎng)設(shè)計(jì)用于停放機(jī)動(dòng)車(chē)輛。用于管理停車(chē)場(chǎng)的方法包括以下步驟：確定停車(chē)場(chǎng)能夠被停放的機(jī)動(dòng)車(chē)占據(jù)的區(qū)域P，確定停放的機(jī)動(dòng)車(chē)當(dāng)前占用的停車(chē)場(chǎng)的面積K，以及確定基于關(guān)系Z =（1-K / P）* M，可以在停車(chē)場(chǎng)中額外停放的機(jī)動(dòng)車(chē)輛的數(shù)量Z，其中M包括可以停放在停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的最大數(shù)量很多。 因此，可以以簡(jiǎn)單且魯棒的方式確定停車(chē)場(chǎng)的剩余容納空間有多大。該特定值可以例如在停車(chē)場(chǎng)外的顯示板上指示。 特別優(yōu)選的是，停車(chē)場(chǎng)被設(shè)計(jì)用于以非組織的方式停放機(jī)動(dòng)車(chē)輛。在這種情況下，通常不為單個(gè)機(jī)動(dòng)車(chē)輛提供停車(chē)位的劃分。駕駛員可以以實(shí)際上任何方式將其機(jī)動(dòng)車(chē)輛停放在停車(chē)場(chǎng)中，優(yōu)選地假設(shè)他們自己將注意不會(huì)妨礙其他機(jī)動(dòng)車(chē)輛。 優(yōu)選地，基于停泊在完全占用的停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的計(jì)數(shù)，以規(guī)則的間隔驗(yàn)證M。計(jì)數(shù)可以特別手動(dòng)地進(jìn)行。為了這個(gè)目的，沒(méi)有必要一個(gè)人通過(guò)停車(chē)場(chǎng)來(lái)計(jì)算機(jī)動(dòng)車(chē)輛;而是可以基于圖像形式的掃描結(jié)果來(lái)執(zhí)行計(jì)數(shù)。因此可以以簡(jiǎn)單和成本有效的方式驗(yàn)證或校準(zhǔn)該方法。 M可以基于以間隔執(zhí)行的多個(gè)計(jì)數(shù)的平均值來(lái)確定。因此可以提高該方法的魯棒性或精度。 在一個(gè)具體實(shí)施例中，以規(guī)則的間隔重新確定P.這使得可以考慮使得停車(chē)場(chǎng)的一部分不可用的影響，例如由于天氣原因而被阻擋的建筑工地或區(qū)段。 當(dāng)確定P時(shí)，可以排除通過(guò)停車(chē)場(chǎng)的不可用于停放機(jī)動(dòng)車(chē)輛的交通路徑的面積。為此目的，可以基于可用作圖像的掃描結(jié)果來(lái)自動(dòng)檢測(cè)或假設(shè)交通路徑。因此，可以考慮否則難以預(yù)測(cè)的停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的組織結(jié)構(gòu)。 可以額外地停放的機(jī)動(dòng)車(chē)輛的具體數(shù)量Z可以實(shí)時(shí)公布。具體地，可以使得數(shù)字Z在云或web服務(wù)中可訪問(wèn)。在一個(gè)具體實(shí)施例中，還可以公布停車(chē)場(chǎng)的占用圖。占用圖可以基于掃描結(jié)果確定或者可以對(duì)應(yīng)于掃描結(jié)果。 此外，可以確定可以另外停放的機(jī)動(dòng)車(chē)輛的數(shù)量的確定的可靠性。所確定的可靠性可以與所確定的數(shù)Z一起公布，以便為正在為他的機(jī)動(dòng)車(chē)輛尋找免費(fèi)停車(chē)位的駕駛員提供改進(jìn)的決定基礎(chǔ)。 一種計(jì)算機(jī)程序產(chǎn)品包括用于當(dāng)計(jì)算機(jī)程序產(chǎn)品在處理設(shè)備上運(yùn)行或存儲(chǔ)在計(jì)算機(jī)可讀數(shù)據(jù)載體上時(shí)執(zhí)行上述方法的程序代碼裝置。 用于管理上述停車(chē)場(chǎng)的裝置包括用于確定停泊的機(jī)動(dòng)車(chē)輛當(dāng)前占用的停車(chē)場(chǎng)的面積K的掃描裝置以及被設(shè)計(jì)為確定機(jī)動(dòng)車(chē)輛的額外數(shù)量Z的處理裝置，基于關(guān)系Z =（1-K / P）* M。在這種情況下，P包括可被停放的機(jī)動(dòng)車(chē)輛占據(jù)的停車(chē)場(chǎng)的區(qū)域P，M包括可停放在停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的最大數(shù)量。掃描裝置優(yōu)選地包括成像傳感器。使得可以容易地由機(jī)器以及人來(lái)檢測(cè)或評(píng)估掃描結(jié)果。對(duì)于機(jī)器處理，已知用于圖像檢測(cè)的算法。在另一個(gè)具體實(shí)施例中，也可以使用其他傳感器，例如雷達(dá)或激光雷達(dá)，其可以是成像或非成像。還可以使用一個(gè)或多個(gè)成像傳感器和一個(gè)或多個(gè)非成像傳感器的組合。附圖說(shuō)明參考附圖更詳細(xì)地描述本發(fā)明。具體實(shí)施方式圖示出了具有管理裝置的停車(chē)場(chǎng)。具體實(shí)施方式圖示出了具有管理裝置的停車(chē)場(chǎng).停車(chē)場(chǎng)設(shè)計(jì)用于無(wú)組織的停車(chē)場(chǎng)，也就是說(shuō)，沒(méi)有或者沒(méi)有精確地規(guī)定可以停放在停車(chē)場(chǎng)中的單個(gè)機(jī)動(dòng)車(chē)輛，將布置機(jī)動(dòng)車(chē)輛。特別地，機(jī)動(dòng)車(chē)輛可以占據(jù)的停車(chē)位的寬度或長(zhǎng)度可能是未定義的。此外，還可以自由地選擇在停車(chē)場(chǎng)中形成機(jī)動(dòng)車(chē)輛的行或其它布置的模式。在這種情況下，機(jī)動(dòng)車(chē)輛的每個(gè)駕駛員可以有助于形成組織結(jié)構(gòu)。停車(chē)場(chǎng)可以包括入口和出口.在本表示中，兩者在物理上一致;但是它們也可以彼此分離地設(shè)置。此外，可以提供多個(gè)入口或多個(gè)出口.管理裝置被設(shè)計(jì)為確定在給定時(shí)間點(diǎn)可以在停車(chē)場(chǎng)中額外停放的機(jī)動(dòng)車(chē)輛的數(shù)量。為此，管理裝置包括處理設(shè)備，其連接到掃描設(shè)備.掃描設(shè)備可以例如使用雷達(dá)，激光雷達(dá)，超聲波，可見(jiàn)光或不可見(jiàn)光來(lái)操作。掃描設(shè)備優(yōu)選地是成像，即，或三維表示。該表示包括多個(gè)圖像元素，其值表示停車(chē)場(chǎng)或機(jī)動(dòng)車(chē)輛的部分。優(yōu)選地，掃描裝置安裝在停車(chē)場(chǎng)上方的高度以便從鳥(niǎo)瞰圖執(zhí)行掃描。例如，掃描裝置可以安裝在建筑物的高架部分，柱子或柱子上。這是一個(gè)很好的選擇，特別是在停車(chē)場(chǎng)處于開(kāi)啟狀態(tài)的情況下，但是所描述的技術(shù)原則上也可以在被覆蓋的停車(chē)場(chǎng)的情況下使用，并且是停車(chē)場(chǎng)或地下停車(chē)設(shè)施。在一個(gè)具體實(shí)施例中，可以提供多個(gè)掃描裝置，其數(shù)據(jù)可以由處理裝置組合以便提供停放在其中的機(jī)動(dòng)車(chē)輛的停車(chē)場(chǎng)的完整圖片。在圖像的基礎(chǔ)上或由處理裝置提供的具有停泊的機(jī)動(dòng)車(chē)輛的停車(chē)場(chǎng)的表示，可以確定當(dāng)前由機(jī)動(dòng)車(chē)輛占據(jù)的停車(chē)場(chǎng)的面積K.通過(guò)知道停車(chē)場(chǎng)的總面積P ，可以確定停車(chē)場(chǎng)被填充的程度為Q = K / P。如果這個(gè)商Q乘以可以停放在停車(chē)場(chǎng)中的機(jī)動(dòng)車(chē)輛的最大數(shù)量M，則這產(chǎn)生當(dāng)前仍然可以停放的機(jī)動(dòng)車(chē)輛的數(shù)量Z.作為公式，這可以表示如下：Z =（1-Q）* M =（1-K / P）* M。能夠被停放的機(jī)動(dòng)車(chē)輛占用的停車(chē)場(chǎng)的區(qū)域P優(yōu)選地不包括不可用于停放機(jī)動(dòng)車(chē)輛的交通路徑.通常需要交通路徑，以便允許每個(gè)停放的電動(dòng)機(jī)優(yōu)選地，還提供了足夠的交通路徑，以便機(jī)動(dòng)車(chē)輛從入口開(kāi)始到達(dá)可用作機(jī)動(dòng)車(chē)輛的停車(chē)位的停車(chē)場(chǎng)的空閑區(qū)域。停車(chē)場(chǎng)中的交通路徑的位置可以隨著時(shí)間改變，例如當(dāng)機(jī)動(dòng)車(chē)輛的組織原理改變時(shí)。如圖所示，機(jī)動(dòng)車(chē)輛通過(guò)示例的方式布置成列;盡管在另一個(gè)時(shí)間點(diǎn)上例如也可以出現(xiàn)排列。然后，交通路徑必須與表示中不同，即水平而不是垂直地定向?？捎糜谕７艡C(jī)動(dòng)車(chē)輛的停車(chē)場(chǎng)的區(qū)域P可以改變。例如如果停車(chē)場(chǎng)的一部分不能由機(jī)動(dòng)車(chē)輛從入口到達(dá)，例如如果在冬天停車(chē)場(chǎng)的一段被一堆雪占據(jù)或者如果停車(chē)場(chǎng)的一段不能用于在強(qiáng)降雨中由于水的積累。優(yōu)選地，區(qū)域P由處理裝置基于由掃描裝置提供的表示來(lái)確定。確定的頻率可以等于或低于Z的確定頻率，即機(jī)動(dòng)車(chē)輛的頻率其可以在停車(chē)場(chǎng)中額外停放。優(yōu)選地，對(duì)于Z的每次確定，由掃描裝置執(zhí)行至少一次掃描?？梢灾芷谛缘卮_定Z，例如每月或每四分之一小時(shí)。該確定還可以是事件驅(qū)動(dòng)的，例如如果從正在為他的機(jī)動(dòng)車(chē)輛尋找停車(chē)位的駕駛員接收到請(qǐng)求。該請(qǐng)求可以從智能電話或從安裝在機(jī)動(dòng)車(chē)輛中的計(jì)算機(jī)發(fā)送，例如，為此目的優(yōu)選無(wú)線數(shù)據(jù)傳輸?？梢栽谕＼?chē)場(chǎng)中額外停放的機(jī)動(dòng)車(chē)輛的具體數(shù)量Z可以通過(guò)顯示板以圖形或數(shù)字方式表示。替代地或附加地，

原文： Management of parking lot Abstract: A parking lot is designed for parking motor vehicles in a non-organized manner. A method for managing the parking lot includes steps of determining an area P of the parking lot that is able to be occupied by parked motor vehicles, of determining an area K of the parking lot that is currently occupied by parked motor vehicles, and of determining a number Z of motor vehicles that may be parked additionally in the parking lot, on the basis of the relationship Z=(1?K/P)*M, where M comprises a maximum number of motor vehicles that may be parked in the parking lot. Keywords: parking lot, management, motor vehicle backgroung information A parking lot is designed to accommodate a number of motor vehicles that may be parked within it. In this instance, there is no concrete prescription as to the manner or the order in which the motor vehicles are to be parked in the parking lot. An arrangement of motor vehicles in the parking lot may therefore change. In contrast to an organized parking lot, in which parking spaces are identified that may be respectively occupied by a motor vehicle, it is difficult to manage a non-organized parking lot. In particular, it may be difficult to determine a number of the motor vehicles that at a given time may be additionally parked in the parking lot. The present invention is based on the objective of providing a technology for managing a parking lot that is designed for parking motor vehicles. SUMMARY A parking lot is designed for parking motor vehicles. A method for managing the parking lot includes steps of determining an area P of the parking lot that is able to be occupied by parked motor vehicles, of determining an area K of the parking lot that is currently occupied by parked motor vehicles, and of determining a number Z of motor vehicles that may be parked additionally in the parking lot, on the basis of the relationship Z=(1?K/P)*M, where M comprises a maximum number of motor vehicles that may be parked in the parking lot. Thus it is possible to determine in a simple and robust manner how large the remaining accommodation capacity of the parking lot is. The specific value may be indicated for example on a display board outside of the parking lot. It is in particular preferred that the parking lot is designed for parking motor vehicles in a non-organized manner. In this context, usually no demarcations of parking spaces are provided for individual motor vehicles. Drivers may park their motor vehicles in practically any manner in the parking lot, it being preferably assumed that they themselves will take care that no other motor vehicle is thereby impeded. M is preferably verified at regular intervals on the basis of a count of the motor vehicles parked in the fully occupied parking lot. The count may be carried out in particular manually. For this purpose, it is not necessary that a person walk through the parking lot in order to count the motor vehicles; rather, the count may be performed on the basis of a scanning result in the form of an image. It is thus possible to verify or calibrate the method in a simple and cost-effective manner. M may be determined on the basis of an average value of multiple counts performed at intervals. The robustness or precision of the method may thus be increased. In one specific embodiment, P is determined anew at regular intervals. This makes it possible to take influences into account that make a part of the parking lot unusable such as for example a construction site or a section that is blocked off for weather-related reasons. When determining P, the area of traffic paths through the parking lot, which are not available for parking motor vehicles, may be excluded. For this purpose, the traffic paths may be detected or assumed automatically on the basis of a scanning result that is available as an image. It is thus possible nevertheless to take into account the organizational structure of motor vehicles in the parking lot that is otherwise difficult to predict. The specific number Z of motor vehicle that may be parked additionally may be published in real time. In particular, the number Z may be made accessible in a cloud or a web service. In one specific embodiment, it is also possible to publish an occupancy map of the parking lot. The occupancy map may be determined on the basis of the scanning result or may correspond to it. Moreover, it is possible to determine a reliability of the determination of the number of motor vehicles that may be parked additionally. The determined reliability may be published together with the determined number Z in order to offer a driver, who is looking for a free parking space for his motor vehicle, an improved basis for a decision. A computer program product includes program code means for carrying out the method described above when the computer program product is run on a processing device or is stored on a computer-readable data carrier. A device for managing the above-described parking lot includes a scanning device for determining an area K of the parking lot that is currently occupied by parked motor vehicles and a processing device that is designed to determine a number Z of motor vehicles that may be additionally parke in the parking lot, on the basis of the relationship Z=(1?K/P)*M. In this instance, P comprises the area P of the parking lot that may be occupied by parked motor vehicles, and M comprises a maximum number of motor vehicles that may be parked in the parking lot.The scanning device preferably includes an imaging sensor.This makes it possible to detect or evaluate the scanning result easily both by a machine as well as by a person. For machine-processing, algorithms for image detection are known. In another specific embodiment, other sensors may be used as well, for example radar or lidar, which alternatively may be imaging or non-imaging. It is also possible to use a combination of one or multiple imaging sensors and one or multiple non-imaging sensors.BRIEF DESCRIPTION OF THE DRAWINGSThe present invention is described in more detail with reference to the FIGURE.FIG. 1 shows a parking lot having a management device.DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTSFIG. 1 shows a parking lot 100 having a management device 105. Parking lot 100 is designed for non-organized parking, that is, it is not or is not precisely prescribed for individual motor vehicles 110, which may be parked in parking lot 100, how the motor vehicles 110 are to be arranged. In particular, the width or length of a parking space that a motor vehicle 110 may occupy may be undefined. Also a pattern, according to which rows or other arrangements of motor vehicles 110 are formed in the parking lot 100, may be freely selectable as well. In this context, each driver of a motor vehicle 110 may contribute toward forming an organizational structure.Parking lot 100 may include an entrance 115 and an exit 120. In the present representation, both coincide physically; but they may also be provided as separate of each other. Furthermore, multiple entrances 115 or multiple exits 120 may be provided.Management device 105 is designed to determine a number of motor vehicles that at a given point in time may be parked additionally in parking lot 100. For this purpose, management device 105 includes a processing device 125, which is connected to a scanning device 130. Scanning device 130 may operate for example using radar, lidar, ultrasound, visible or invisible light.Scanning device 130 is preferably imaging, that is, it is designed to provide a two- or three-dimensional representation of parking lot 100. The representation comprises a plurality of image elements, whose values represent portions of parking lot 100 or of a motor vehicle 110. It is preferred that scanning device 130 is mounted at an elevation above parking lot 100 in order to perform the scan from the bird's eye view. Scanning device 130 may be mounted on an elevated part of a building, a post or a pillar, for example. This is a good option particularly in the case a parking lot 100 that is in the open, but the technology described may in principle also be used in the case of a parking lot that is covered and that is part of a parking garage or an underground parking facility, for example. In one specific embodiment, multiple scanning devices 130 may be provided, the data of which may be combined by processing device 125 in order to provide a complete picture of parking lot 100 with the motor vehicles 110 parked in it.On the basis of the image or the representation of parking lot 100 with parked motor vehicles 110 provided by processing device 125, it is possible to determine an area K of the parking lot that is currently occupied by motor vehicles 110. With the knowledge of the total area P of parking lot 100, it is possible to determine the degree to which parking lot 100 is filled as Q=K/P. If this quotient Q is multiplied by the maximum number M of motor vehicles 110 that may be parked in parking lot 100, then this yields the number Z of motor vehicles 110 that may currently still be parked. As a formula, this may be represented as follows:Z=(1?Q)*M=(1?K/P)*M. The area P of parking lot 100, which is able to be occupied by parked motor vehicles 110, preferably does not include traffic paths 135 that are not available for parking motor vehicles 110. Traffic paths 135 are generally required in order to allow every parked motor vehicle to reach exit 120. Preferably, sufficient traffic paths 135 are also provided in order for a motor vehicle 110, starting from the entrance, to reach a free area of parking lot 100 that is usable as a parking space for a motor vehicle 110.The location of a traffic path 135 in parking lot 100 may change over time, for example when the organizational principle of motor vehicles 110 changes. In FIG. 1, motor vehicles 110 are arranged in columns by way of example; although at another point in time an arrangement in rows may come about as well for example. Traffic paths 135 would then have to be oriented differently than in the representation, namely, horizontally instead of vertically.The area P of the parking lot usable for parking motor vehicles 110 may change over time, for example if a section of parking lot 100 cannot be reached by a motor vehicle 110 from entrance 115, for example if in winter a section of parking lot 100 is occupied by a pile of snow or if a section of parking lot 100 cannot be used in a strong rain fall due to water accumulation. It is preferred that the area P is determined by processing device 125 on the basis of the representation provided by scanning device 130. The frequency of the determination may be equal to or lower than the frequency of determination of Z, i.e., of motor vehicles 110 that may be parked additionally in parking lot 100. Preferably, for each determination of Z, at least one scan is performed by scanning device 130. Z may be determined periodically, for example monthly or every quarter of an hour. The determination may also be event-driven, for example if a request is received from a driver who is looking for a parking space for his motor vehicle 110. The request may be sent from a smart phone or from a computer installed in motor vehicle 110, for example, a wireless data transmission being preferred for this purpose.The specific number Z of motor vehicles 110 that may be parked additionally in parking lot 110 may be represented graphically or numerically via a display board 140. Alternatively or additionally, the specific number Z may also be published digitally, for example as a web service or in a cloud.How well the determined number of motor vehicles 110 that may be parked additionally in parking lot 100 matches the actual motor vehicles 110 that may still be parked in parking lot 100 usually depends on a degree to which parking lot 100 is filled. This degree of usage corresponds to the quotient Q mentioned above. In the exemplary representation of FIG. 1, two additional motor vehicles 110 were determined that are able to find room in parking lot 100. In the row of parked motor vehicles 110 in the left area of parking lot 100 of FIG. 1, there is a corresponding space that could be occupied by another motor vehicle 110. On the right side, by contrast, no space is formed since adjacent motor vehicles 110 of this row are spaced too far apart from one another. The determined number Z therefore deviates by 1 from the actual number of motor vehicles 110 that may still be accommodated in the parking lot. This corresponds to an absolute error of only 1, but to a relative error of 50%.The lower the degree Q to which parking lot 100 is filled, the more probable it is that a sufficiently small motor vehicle 110 may still be found that is able to utilize a remaining area that is smaller than the average area required by a motor vehicle 110. If the degree to which parking lot 100 is filled approaches 100%, however, then the possibilities of tight parking are nearly exhausted.It is possible to determine a reliability or confidence with which the determined number of motor vehicles 110 that may still be parked in parking lot 100 is correct. In another specific embodiment, it is also possible to determine a probability of the applicability of the determined number. This value may be provided together with the determined number of motor vehicles 110 that may be additionally parked. The representation of FIG. 1 shows on display board 140 on the right side an exemplary traffic light-like structure that indicates degree of reliability of the determined displayed value. As an alternative to the symbolic representation, a graphic representation may also be used. 指 導(dǎo) 教 師 評(píng) 語(yǔ) 外文翻譯成績(jī)： 指導(dǎo)教師簽字： 年 月 日 注：1. 指導(dǎo)教師對(duì)譯文進(jìn)行評(píng)閱時(shí)應(yīng)注意以下幾個(gè)方面：①翻譯的外文文獻(xiàn)與畢業(yè)設(shè)計(jì)（論文）的主題是否高度相關(guān)，并作為外文參考文獻(xiàn)列入畢業(yè)設(shè)計(jì)（論文）的參考文獻(xiàn)；②翻譯的外文文獻(xiàn)字?jǐn)?shù)是否達(dá)到規(guī)定數(shù)量（3 000字以上）；③譯文語(yǔ)言是否準(zhǔn)確、通順、具有參考價(jià)值。 2. 外文原文應(yīng)以附件的方式置于譯文之后。 共 5 頁(yè) 第 12 頁(yè)
