PARKING LOT CORNER POINT CORRECTION METHOD, PARKING LOT CORNER POINT CORRECTION SYSTEM, AND VEHICLE

摘要

The invention relates to a parking lot corner point correction method and system. The method includes: an obtaining step of obtaining a parking lot corner point of a parking lot; and a correction step of performing, based on a position relationship between parking lot corner points of the parking lot, rectangular correction on the parking lot corner points to obtain a corrected parking lot. The obtaining step includes: a first obtaining sub-step of obtaining a parking lot corner point of a parking lot; a determination sub-step of determining whether a corner point confidence level of the parking lot corner point meets a first threshold and whether a corner point offset thereof meets a second threshold, and jumping to the correction step if it is determined that the corner point confidence level meets the first threshold and the corner point offset meets the second threshold, otherwise, proceeding to a second obtaining sub-step; and the second obtaining sub-step of discarding the parking lot corner point of the parking lot that is detected in the first obtaining sub-step, and then using a parking lot corner point at a corresponding position that is predicted by an odometer, as the parking lot corner point of the parking lot. According to the invention, the parking accuracy may be improved.
