Abstract

The invention discloses an automatic calibration method for a surround view system, a car, a calibration device and a storage medium. The automatic calibration method for a surround view system includes: determining a connected domain in an initial image captured by a camera, and dividing the connected domain into marked blocks; Obtain the contour point set and center of each marked block, obtain the first corner point farthest from the center of the corresponding marked block in each contour point set; obtain the second corner point farthest from the first corner point in each contour point set; determine The vertical line connecting the first corner point and the second corner point, determine the projected feet of each contour point on the vertical line in each contour point set, and find the distance between these projected foot points located on both sides of the center of the marker block respectively The two farthest foot points from the center, and the contour points corresponding to these two foot points are the third corner point and the fourth corner point; complete the automatic calibration of the surround view system based on the above corner points. The invention can realize automatic point finding without manual intervention to find points, which brings great convenience to customers.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to an automatic calibration method for a surround view system, a vehicle, a calibration device and a storage medium. Background technique [0002] The car surround view system is composed of multiple fisheye cameras assembled on the car body, each camera covers a certain area around the vehicle, and the images are converted from viewpoints to generate a bird's-eye view of the car. In the process of generating the final vehicle-mounted surround-view bird's-eye view, it is necessary to calibrate the fisheye camera, obtain its internal and external parameters, and then perform distortion correction on the initial image captured by the fisheye camera. [0003] The existing surround view system basically finds the checkerboard corner points on the initial image manually, and calculates the internal and external parameters of the fisheye camera based on these corner points, so as to p...
