Calibration method and device for camera device and calibration equipment

Abstract

The invention discloses a calibration method and device for a camera device and calibration equipment. The method includes: obtaining a plurality of images shot by a camera device for a movable calibration device, wherein the images comprise a calibration reference object arranged on the calibration device; obtaining the position of calibration equipment corresponding to each image; obtaining a relative installation position relationship between the calibration reference object and the calibration equipment; and calibrating the external parameters of the camera device according to the relativeinstallation position relationship, the plurality of images and the position of the calibration equipment corresponding to each image. The calibration equipment can move in a scene in which a to-be-calibrated camera device is deployed; an image acquired by the to-be-calibrated camera device is acquired and processed, a spatial position relation and between a calibration reference object and the to-be-calibrated camera device is constructed, self-positioning is performed, and finally the to-be-calibrated camera device in the scene is automatically and conveniently calibrated. According to themethod, manual calibration operation is not needed, and the calibration efficiency of the camera device is remarkably improved.

Description

[0001] The present invention claims the priority of the Chinese patent application submitted to the State Intellectual Property Office of the People's Republic of China on December 27, 2018, with the application number 201811612158.9, and the application name "a method, equipment and system for calibrating camera devices". The entire contents are incorporated herein by reference. technical field [0002] The present application relates to the technical field of calibration of instruments and equipment, in particular to a calibration method, device and calibration equipment for an imaging device. Background technique [0003] With the wide application of camera devices, at present, a large number of camera devices are used in many areas to monitor the area. Now there are some technologies to track moving targets in the scene by calling the images collected by the camera device deployed in the scene. [0004] Calibration of instruments and equipment is a routine method used i...

AI Technical Summary

Problems solved by technology

[0005] The existing camera calibration methods usually require manual operation, which not only consumes manpower, but also has a very high time cost.

When the scene area where the camera is deployed is very large and there are a large number of cameras deployed, it is obviously a very cumbersome task to rely on manpower to calibrate the camera
