Method, device and system for calibrating camera device

Abstract

The invention discloses a method, device and system for calibrating a camera device. The method includes: determining a target camera device from all uncalibrated camera devices by utilizing the position information set and the real-time position information of the calibration equipment; and when it is determined that the calibration reference image of the target camera device is collected, updating the calibration state of the target camera device from the first state to the second state. Therefore, whether the calibration reference image of each camera device in the scene is acquired or notcan be known according to the calibration state of the device in the scene. In addition, the target camera device is determined by utilizing the position information set and the real-time position information of the calibration equipment, so that the orderliness of acquiring the calibration reference image of the camera device is ensured. Therefore, according to the technical scheme of the invention, the collection efficiency of the calibration reference image of the camera device is improved, repeated collection or missing collection is avoided, and the calibration efficiency is further improved.

Description

technical field [0001] The present application relates to the technical field of calibration of instruments and equipment, in particular to a method, device and system for calibrating an imaging device. Background technique [0002] With the wide application of camera devices, at present, a large number of camera devices are used in many scenes to monitor areas, such as shopping malls or amusement parks. 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. [0003] Calibration of instruments and equipment is a routine method used in optical, electrical and mechanical fields to obtain accurate measurement results. In practical applications, if the parameters of the cameras deployed in the scene are not calibrated, the accuracy of the monitoring results obtained is poor. For example, it is difficult to link the motion trajectories of the same target object obtained by using the videos...

Problems solved by technology

[0005] However, in the specific implementation process of the above technologies, the problems of missing calibration and repeated calibration are prone to occur.

If a calibration leak occurs, it is necessary to drive the calibration device to move again to the shooting area of ​​the camera device that missed the calibration to collect images, which brings inconvenience to the calibration task and wastes time

Unnecessary time consumption if recalibration occurs
