Parameter correction method, device and system, electronic equipment and storage medium

Abstract

The embodiment of the invention provides a parameter correction method, device and system, electronic equipment and a storage medium, and relates to the technical field of computers, and the method comprises the steps: obtaining a to-be-compared feature of a to-be-compared image obtained by carrying out the image collection of a projection result through image collection equipment fixedly installed on a vehicle; in a pre-obtained image feature set, determining image features similar to the to-be-compared features as similar features; obtaining external parameters of the image acquisition equipment when the images corresponding to the determined similar features are acquired, and taking the external parameters as similar feature external parameters; and correcting the current external parameters of the image acquisition equipment according to the obtained similar feature external parameters. When the scheme provided by the embodiment of the invention is applied to parameter correction, the accuracy of external parameters of the image acquisition equipment can be improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a parameter correction method, device, system, electronic equipment and storage medium. Background technique [0002] In order to facilitate the driver to observe around the vehicle body, a plurality of cameras are usually assembled on the vehicle body, and the shooting range of each camera can cover a certain area, and the shooting range of all cameras can cover the area around the vehicle body. In the prior art, by adjusting the viewpoint of the images collected by each camera, the top view of the ground coordinate system is obtained, and then according to the preset external parameters of each camera, the obtained top views are spliced ​​to generate a surround view. The seamless mosaic map around the car body is used as a top view of the vehicle. Wherein, the external parameters of the camera are referred to as extrinsics, including the abscissa, ordinate, vertical ...

AI Technical Summary

Problems solved by technology

When the external parameters of the camera change, the size and angle of the image captured by the camera will also change. In this case, the above-mentioned preset external parameters are no longer accurate. Collecting parameters to generate the top view of the vehicle's surround view will cause the generated top view of the vehicle to be misplaced, and the relative positions of objects in the top view of the vehicle's surround view are not accurate enough
