Parking stall identification compensation method based on ultrasonic sensor parking stall detection system

The invention relates to a parking stall identification compensation method based on an ultrasonic sensor parking stall detection system. The method comprises the steps that an ultrasonic radar obtains the shape types of barriers in upper and lower edges of a target parking stall, and the widths of the barriers in the upper and lower edges and distance between the upper and lower edges of the target parking stall are calculated simultaneously; compensation values of the upper and lower edges of the target parking stall are determined; and the length of the target parking stall is calculated according to the distance between the upper and lower edges and the compensation values of the upper and lower edges. The ultrasonic radar obtains barrier characteristics of the upper and lower edges ofthe target parking stall, the upper and lower edges of the target parking stall are compensated by combining the vehicle speed, the target parking stall is identified accurately, the identification method is highly robust an
