The invention discloses a parking space state analysis method and system based on cloud edge fusion. The method comprises the following steps: judging whether a parking space number has corresponding historical parking space cache information or not; if not, the parking space calibration coordinates are converted according to a three-dimensional projection algorithm, a three-dimensional parking space projection frame corresponding to the parking space number is obtained, and the parking state of each vehicle is calculated according to the three-dimensional parking space projection frame and each vehicle detection frame; if yes, whether each vehicle detection frame exists in historical parking space cache information or not is judged; if yes, the parking state of the vehicle corresponding to each vehicle detection frame is called according to the historical parking space cache information; if not, the parking state of the vehicle corresponding to the vehicle detection frame is calculated according to the three-dimensional parking projection frame and the vehicle detection frame; according to the parking state of each vehicle, whether a vehicle exists in a parking space corresponding to the parking space number is judged; if yes, determining that the vehicle exists in the parking space corresponding to the parking space number; and if not, determining that the vehicle does not exist in the parking space corresponding to the parking space number.

    本申请公开一种基于云边融合的泊位状态分析方法以及系统。方法包括:判断泊位编号是否存在对应的历史泊位缓存信息;若否,则根据三维投影算法对泊位标定坐标进行变换,获得泊位编号对应的三维泊位投影框,并根据三维泊位投影框与每个车辆检测框,计算每个车辆的停靠状态;若是,则判断每个车辆检测框是否存在于历史泊位缓存信息中;若是,则根据历史泊位缓存信息,调用每个车辆检测框对应的车辆的停靠状态;若否,则根据三维泊位投影框与车辆检测框,计算车辆检测框对应的车辆的停靠状态;根据每个车辆的停靠状态,判断泊位编号对应的泊位内是否存在车辆;若是,则泊位编号对应的泊位内存在车辆;若否,则泊位编号对应的泊位内不存在车辆。
