Problems solved by technology

If the placement of the monocular camera is not accurate enough, the automatic driving data output by the autonomous driving vehicle will not be accurate enough
[0003] In the prior art, the installation angle is usually obtained by manually adjusting the camera parameters, but manually adjusting the camera placement angle often takes a long time and the adjusted camera placement angle is not accurate enough

Abstract

The invention relates to a method and device for adjusting the placement angle of a monocular camera. The method comprises the following steps: acquiring a shot image of a monocular camera, wherein the shot image comprises a reference object; dividing the shot image into at least two areas, wherein each area comprises a reference object image; identifying key points of the reference object image in each region, and respectively acquiring pixel feature values of the at least two regions according to the key points of the reference object image; and comparing the pixel characteristic values of the at least two areas, and determining the adjustment angle of the monocular camera. According to the scheme provided by the invention, installation personnel can be assisted to quickly obtain and adjust the placement angle of the monocular camera.

Description

technical field [0001] This application relates to the field of intelligent transportation, and in particular to a method for adjusting the placement angle of a monocular camera. Background technique [0002] In the related art, in the field of intelligent transportation, several cameras need to be installed on the vehicle to collect image information. When evaluating the shooting accuracy of the camera, the shooting accuracy of the camera is mainly calculated by obtaining the external parameters of the camera. The external participation of the camera is related to two aspects, one is the installation posture of the camera, and the other is the installation position of the camera. By installing the camera in different ways, different external parameters can be obtained, and then the data related to automatic driving can be analyzed according to the size and accuracy of the effective range of the external parameters. If the placement of the monocular camera is not accurate ...
