AI Technical Summary
Technical Problem
In existing technologies, the accuracy of trailer attitude perception is low due to significant errors in obtaining the trailer angle.
Method used
By setting a preset target on the trailer, acquiring and correcting the image to be perceived, obtaining the target shape using binary semantic segmentation, determining the vanishing point of the target shape, and thus determining the trailer attitude.
Benefits of technology
It improves the accuracy of trailer attitude perception, significantly enhancing the accuracy of perception results compared to existing technologies.

Abstract
The present application relates to the technical field of image recognition, and discloses a trailer posture sensing method, device, equipment and storage medium, the method comprising: obtaining a to-be-sensed image of a to-be-sensed trailer, the to-be-sensed image containing a preset target, the preset target being arranged on the to-be-sensed trailer; correcting the to-be-sensed image, and performing two-class semantic segmentation on the corrected to-be-sensed image to obtain a target shape of the preset target; determining a vanishing point of the target shape according to the target shape, and determining a trailer posture of the to-be-sensed trailer based on the vanishing point. The preset target is arranged on the to-be-sensed trailer, and the to-be-sensed image with the preset target is obtained, the to-be-sensed image is corrected and two-class semantic segmentation is performed, the target shape of the preset target is obtained, and then the trailer posture of the to-be-sensed trailer is determined based on the vanishing point in the target shape, compared with the existing trailer posture obtained by the trailer angle, the preset target is used to improve the accuracy of the trailer posture sensing.
