【摘要】：经济的发展促进了人们生活水平的提高,城市中汽车也越来越多,这就催生了许多规模庞大的商场、机场、影院等,同时其配套的停车场规模也越来越大。数量巨大、规模庞大的停车场在帮助人们解决停车难问题的同时,也为人们带来了寻车难的困扰。因此反向寻车应运而生,很多企业也进行了大量的尝试,并提出了多种不同的解决方案,如刷卡寻车、视频寻车等等。各种解决方案都各自有优缺点,如有的寻车精度低,有的实施成本高等,都不能完美有效的解决此类问题。因此反向寻车仍然是需要人们不断探索和亟待解决的问题。针对反向寻车问题,本文主要研究了以下内容：首先,阐述了地下停车场寻车问题的背景与意义,并分析了反向寻车领域研究现状与趋势,以此给出反向寻车系统研究的必要性。介绍了数据结构相关的基础知识,尤其是图论的相关知识,并给出了迪杰斯特拉算法原理与步骤的详细描述和java代码实现,这些是反向寻车设计的基础。然后,简要分析了地下停车场特点,提出了一种地下停车场地图文件设计并给出了详细的解释。该文件内容能够抽象为图的模型,进而可以利用图的相关知识进行地图线路的计算。还介绍了tmx地图格式以及如何使用Tiled地图编辑器绘制tmx格式地图,介绍了如何将tmx格式地图转换为本文提出的停车场地图设计。最后,基于提出的停车场地图设计,本文给出了地图设计向图的模型的转换算法步骤。设计并实现了停车场反向寻车系统,它包括服务器端和手持终端,然后对系统的部分功能进行了介绍。
[Abstract]:The development of economy has promoted the improvement of people's living standard, and there are more and more cars in the city, which has given birth to a lot of large-scale shopping malls, airports, cinemas and so on, at the same time, the scale of its supporting parking lot is also getting larger and larger. The large number of parking lots not only helps people solve the problem of parking difficulties, but also brings the trouble of finding cars. As a result, many enterprises have made a lot of attempts, and put forward a variety of different solutions, such as swipe car, video car search and so on. All kinds of solutions have their own advantages and disadvantages, such as some low precision, some implementation cost high, can not solve this kind of problem perfectly and effectively. Therefore, reverse search is still a problem that needs to be explored and solved. Aiming at the problem of reverse car searching, this paper mainly studies the following contents: firstly, the background and significance of the problem in underground car park are expounded, and the present situation and trend of the research in the field of reverse car hunting are analyzed. Based on this, the necessity of the research on reverse vehicle tracing system is given. This paper introduces the basic knowledge of data structure, especially the related knowledge of graph theory, and gives a detailed description of the principle and steps of Dijstra algorithm and the implementation of java code, which are the basis of reverse vehicle tracing design. Then, the characteristics of underground parking lot are briefly analyzed, and a map file design of underground parking lot is put forward and explained in detail. The content of this document can be abstracted as a graph model, and then the map circuit can be calculated by using the relevant knowledge of the graph. The paper also introduces the tmx map format and how to use the Tiled map editor to draw the tmx format map, and how to convert the tmx format map into the parking lot map design proposed in this paper. Finally, based on the proposed design of the parking lot map, this paper presents the algorithm steps of the model transformation from map design to graph. The reverse car searching system of parking lot is designed and implemented, which includes server and handheld terminal. Then some functions of the system are introduced.
