The invention discloses a parking space detection method based on multi-sensor fusion. The method comprises the following steps: (1) subjecting an obtained all-round image to an all-round image parking space detection algorithm to obtain coordinates of four corners of a parking space; (2) mapping the obtained distance information of the surrounding obstacles into coordinate points of the obstacles on the look-around image through an ultrasonic distance detection algorithm; and (3) fusing the coordinate points of the obstacle in the step (2) and the coordinates of the four corners of the parking space in the step (1) in a vehicle body coordinate system through a fusion algorithm, and judging whether parking can be carried out or not, wherein the step (1) and the step (2) are carried out at the same time. The parking space detection system comprises a look-around image parking space detection module, an ultrasonic distance detection module and a fusion module. In the automatic parking process, information of various vehicle-mounted sensors is fused, and the accuracy of parking space detection is improved; and the method is applied to various types of parking lots, and the stability of the automatic parking system is improved.
