[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.
