基于ARM嵌入式系统的空闲车位检测方法

针对室外停车场,给出一种摄像头检测空车位的方案。基于最大后验概率的意义,将车位状态组合问题转变为最短网络路径的求解,给出了求解该网络最短路径的快速算法。通过内嵌ARM11系统的智能摄像头进行图像拍摄和车位检测算法的快速运算,实时检测车位状态,然后,把检测结果传送到服务器。基于C/S网络模型,用户可以从计算机终端和液晶屏观察和查询车位信息。实验表明,该系统可以方便地用于准确检测空闲车位,同时,实现停车场的信息管理。

Approach for parking spaces detection based on ARM embedded system

Abstract: In order to detect parking spaces of outdoor parking, a proposal using cameras is given. Based on MAP, the problem is translated into the shortest path problem, the fast solving algorithm of which is present. It detects real-time parking space states, sent to the server, by the intelligent camera embedded ARM11, in which there exists the fast parking detection algorithm. Based on the C/S network model, parking information is displayed on computer terminals or LCDs. Experimental results indicate that the system can be conveniently used to detect parking space states, and to manage parking information.
