[0035] It can be known from the background technology that the existing calibration board detection method still needs improvement.
[0036] The analysis is now combined with a calibration board detection method. The calibration board detection method includes: acquiring a first-type calibration board image taken by a corresponding on-board panoramic camera; and identifying the preset first type from the corresponding first-type calibration board image. The position coordinates of the number of marking dots in the image coordinate system of the corresponding car panoramic camera; determine the initial external parameters of the corresponding car panoramic camera.
[0037] The accuracy of the initial external parameters obtained by the above-mentioned calibration board detection method is low, which results in poor splicing effect of the surrounding images of the vehicle. The reasons are analyzed:
[0038] In the process of identifying the mark dots in the image of the first type of c...
