The invention discloses a vehicle parking state detection method, detection devices are installed at the joints of every two adjacent parking spaces. The front side and the rear side of each detectiondevice are provided with a visual recognition unit used for recognizing a vehicle license plate and a distance detection unit used for detecting the distance between the detection device and the edgeof a vehicle. The visual identification unit and the distance detection unit at the front end face the parking space at the front end of the joint, and the visual identification unit and the distancedetection unit at the rear end face the parking space at the rear end of the joint. The vehicle license plate recognition unit can recognize a vehicle license plate so as to judge whether the type ofthe vehicle parked in the parking space meets the specification or not. The distance detection unit detects the distance when the vehicle enters the parking space, so that the continuous linear change track of the vehicle is obtained, the parking position of the vehicle is obtained through judgment, and accurate vehicle occupation resource information is obtained.
一种车辆停车入位状态检测方法,通过在两个相邻的车位的交接处均安装有检测装置,每个检测装置的前后两侧分别设置有用于识别车辆号牌的视觉识别单元以及用于检测与车辆边缘距离的距离探测单元,位于前端的视觉识别单元及距离探测单元朝向交接处前端的车位,位于后端的视觉识别单元及距离探测单元朝向交接处后端的车位。车辆号牌识别单元可以识别车辆号牌从而判断停车入位的车辆类型是否符合规定。距离探测单元对车辆进入车位时的距离进行探测,进而得到车辆连续线性变化的轨迹,从而判断得到车辆停车位置并获得准确的车辆占用资源信息。
