The invention discloses a parking lot multi-target parking space state recognition system, relates to the technical field of intelligent parking lots, and can realize multi-target parking space state real-time monitoring. In the parking lot multi-target parking space state recognition system, a receiving end infrared reflection target is composed of a light reflection panel made of a high light reflection material and a liquid crystal screen with a liquid crystal shutter, and the receiving end infrared reflection target is installed on the ground surface of a parking space center according to specific requirements; the vector target receives continuous light from the illumination light source, and the continuous light penetrates through the liquid crystal screen and is reflected by the reflective panel; the liquid crystal shutter controller controls the liquid crystal shutter to complete opening and closing in a specified frequency and coding mode and converts reflected light into pulsed light in a corresponding coding format to be sent to the high-speed camera, and the high-speed camera receives light information in the corresponding format to position a target and judges whether the position of the target is compliant or not.

    一种车场多目标车位状态识别系统,涉及智能停车场技术领域,其能够实现多目标车位状态实时监测。所述车场多目标车位状态识别系统中,接收端红外反射靶标由高反光材料制成的反光面板和具有液晶快门的液晶屏构成,并视具体需求安装在泊位中心地表;矢量靶标接收来自照明光源的连续光,并透过液晶屏经反光面板反射;液晶快门控制器控制液晶快门以指定的频率和编码方式完成开关,并将反射光转换成相应编码格式的脉冲光发送至高速照相机,且高速照相机接收对应格式的光信息对靶标进行定位,同时判断目标位置是否合规。
