Problems solved by technology

[0004] However, in the actual scene, due to the limitation of the calibration object size, space occlusion and camera field of view, there may be problems of less common view information and poor calibration accuracy. If the traditional multi-camera module calibration method is still used for multi-camera module Calibration, it is difficult to get the correct calibration results, thus affecting the user experience

Abstract

The invention discloses a calibration method and device, electronic equipment and a medium. The method comprises the following steps of acquiring calibration board information, laying a simulation calibration board in a simulation environment according to the calibration board information, wherein the simulation environment comprises simulation camera modules laid according to simulation camera parameter information of a plurality of simulation camera modules to be calibrated, and when the images acquired by the simulation camera modules meet simulation ending conditions, calibrating the actual camera modules according to simulation information of a simulation calibration board used when the simulation ending conditions are met and the simulation camera parameter information, wherein the actual camera parameter information of the actual camera module is the same as the simulation camera parameter information of the simulation camera module. By means of the method, the simulation information of the simulation calibration board used when the simulation ending condition is met is determined, then accurate calibration of the actual camera module can be achieved by combining the simulation information with the simulation camera parameter information, and therefore the problem that the calibration accuracy of the camera module is poor is solved.

Description

technical field [0001] Embodiments of the present disclosure relate to the technical field of camera calibration, and in particular, to a calibration method, device, electronic equipment, and media. Background technique [0002] With the further maturity of AR and VR technologies, in some fields, such as film and television entertainment, VR real estate, etc., it is usually necessary to perform operations such as 3D reconstruction and panorama stitching through multiple camera modules. [0003] The traditional multi-camera module calibration method requires multiple sets of common-view calibration objects among the camera modules, that is, these calibration objects must be observed by all camera modules to be calibrated. [0004] However, in the actual scene, due to the limitation of the calibration object size, space occlusion and camera field of view, there may be problems of less common view information and poor calibration accuracy. If the traditional multi-camera module...
