The invention discloses a vehicle parking space occupation information detection method and system. The method comprises the following steps: acquiring parking space contour point coordinate information of a parking space in a monitoring image and vehicle contour point coordinate information of a plurality of vehicles; calculating the berth area of the berth according to the berth contour point coordinate information; according to the parking space contour point coordinate information and the vehicle contour point coordinate information, the parking overlapping area is calculated; according to the parking overlapping area and the parking space area, a plurality of area ratios corresponding to the parking space and the vehicles are calculated, and the maximum area ratio in the area ratios is obtained; if the maximum area ratio is zero or the maximum area ratio is larger than zero and smaller than an area threshold value, the parking space is in an idle parking space state; if the maximum area ratio is larger than or equal to the area threshold value, the berth is in a berth occupation state.

    本发明公开一种车辆占用泊位信息检测方法以及系统。方法包括:获取监控图像中泊位的泊位轮廓点坐标信息与多个车辆的车辆轮廓点坐标信息;根据泊位轮廓点坐标信息,计算泊位的泊位面积;根据泊位轮廓点坐标信息与车辆轮廓点坐标信息,计算泊车重叠区域面积;根据泊车重叠区域面积与泊位面积,计算泊位与多个车辆分别对应的多个面积比值,并获取多个面积比值中最大面积比值;若最大面积比值为零或者最大面积比值大于零且小于面积阈值,则泊位为空闲泊位状态;若最大面积比值大于或等于面积阈值,则泊位为占用泊位状态。
