Abstract

The embodiment of the invention discloses an image acquisition equipment correction method and device, equipment and a medium, and the method comprises the steps: responding to an inspection task starting request, and collecting an image of a target inspection point through image acquisition equipment; if the sharpness of the acquired image does not meet the set sharpness requirement, adjusting internal parameters of the image acquisition equipment; if the sharpness of the acquired image meets a set sharpness requirement, matching the acquired image with a reference image of the target inspection point; adjusting external parameters of the image acquisition equipment according to a matching result; by means of the technical scheme, the problems of image blurring and target deviation causedby preset parameter errors due to the fact that the mechanical structure of the camera is changed are solved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular, to a method for calibrating an image acquisition device. Background technique [0002] The substation inspection system is composed of inspection host, robot, video equipment, etc., and realizes functions such as data collection, automatic inspection, intelligent analysis, real-time monitoring, intelligent linkage and remote operation. The substation inspection system uses computer image processing, analysis and other technologies to extract the target and object features in the collected images, so as to identify the values ​​of different target and object areas in the image, so as to ensure the safety of system equipment operation sex. [0003] Usually, the terminal for collecting images includes the mobile camera to which the robot belongs (such as wheeled robot and track robot) and the fixed camera (such as pan-tilt camera, spherical camera a...
