Embodiment Construction

[0128] As described above, the current calibration of camera devices is prone to missing calibration or repeated calibration, which seriously affects the calibration efficiency. In order to solve this problem, the inventor provides a method, device and system for calibrating an imaging device after research. In this application, the unmarked target camera device in the scene is determined by combining the position information set and the real-time position information of the movable calibration equipment in the scene; The calibration state of the camera device is updated from the first state to the second state. In the present application, by determining the target camera device, the acquisition of the calibration reference image of the camera device is more orderly. In addition, by updating the calibration status after the calibration reference image is collected, it is convenient to know whether the calibration reference image of each camera device has been collected, there...

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...
