The invention provides a parking space detection system and a parking space occupancy state obstacle detection method implemented on the system, and the method comprises the steps: through adding a point location recognition step, when an ultrasonic reflection signal is obtained, the ultrasonic detection distance is recognized, and the number of point locations of the ultrasonic reflection signal is also recognized; secondly, in the obstacle judgment step, whether the number of the identified point positions is within a non-zero preset range or not is judged firstly, and if the number of the point positions is zero, it is indicated that no vehicle or no obstacle exists in the parking space at present; if the number of the point locations is within the range, it is considered that an obstacle is recognized in the current parking space; and if the number of the point locations exceeds the range, it is considered that the vehicle is parked in the current parking space, so that the probability of mistakenly recognizing the obstacle as the vehicle is parked is reduced.

    本发明提供车位检测系统以及在该系统上实现的车位占用状态的障碍物检测方法,通过增设点位识别步骤,在获取超声反射信号时除识别超声的检测距离外,还识别该超声反射信号的点位数量,然后在障碍物判断步骤中先判断所识别的点位数量是否在非零的预设范围内:如果点位数量为零则表示该车位当前既没有车辆也没有障碍物;如果点位数量在该范围内则认为在当前车位识别到障碍物;如果点位数量超出该范围则认为当前车位停放有车辆,减少了把障碍物误识别为停放了车辆的几率。
