Embodiment 1

[0021]figure 1 It is a schematic diagram of a multi-angle camera tailmillization device provided in the embodiment of the present invention. The technical solution of this embodiment is suitable for automatically obtaining a calibration image for calibrating the multi-view camera and automatically completing the multi-view camera calibration according to the acquired calibration image. The apparatus includes a calibration plate 1, a moving module 2, and a control module 3, and the moving module 2 is provided below the calibration plate 1 for switching the spatial position state of the calibration plate 1 within the shooting range of the plurality of camera 4; the control module 3 is connected Moving module 2 and a plurality of camera 4, configured to switch the spatial position state of the calibration plate 1 by the moving module 2, and control the plurality of camera 4 at the time of the spatial position state switching of the calibration plate 1 at the same time. Shooting so that...

Embodiment 2

[0043]figure 2 It is a calibration method of the multi-view camera provided by the second embodiment of the present invention, adapted to the multi-view camera calibration device according to the foregoing embodiment, which can be implemented in software or hardware, including the following steps:

[0044]S201, switch the spatial position state of the calibration plate by moving the module.

[0045]Among them, the calibration board 1 can be a flat panel carrying a black and white chess, or a display device with black and white chessboard. Seefigure 1 . It will be appreciated that if the calibration board is displayed with a display device with a black and white chessboard, the size, contrast and position of the black and white chessboard are adjustable, and the adjustment accuracy is pixel level. In one embodiment, the memory connected to the hardware controller of the display device stores at least two preset standard black and white chessboard, and the user can select the appropriate pr...

Abstract

The embodiment of the invention discloses multi-view camera calibration equipment, a calibration method and a storage medium. The equipment comprises: a calibration board; a moving module which is arranged below the calibration plate and is used for switching the spatial position state of the calibration plate in the shooting range of the plurality of cameras; a control module which is connected with the moving module and the cameras and used for switching the spatial position state of the calibration plate through the moving module and controlling the cameras to shoot the calibration plate when the moving module completes switching of the spatial position state of the calibration plate, so that calibration images of the complete calibration plate in the corresponding spatial position states are shot by at least two cameras at the same time until the number of the calibration images shot by every two cameras at the same time reaches the target number; determining calibration results of the corresponding every two cameras according to the calibration images shot by the every two cameras; and completing calibration of all cameras is completed. The problem that an existing multi-view camera calibration method is low in calibration image obtaining efficiency is solved.

Description

Technical field[0001]Embodiments of the present invention relate to the field of shooting equipment, and more particularly to a multi-view camera calibration device, a calibration method, and a storage medium.Background technique[0002]In terms of the development of neuropsic drugs, the difference in behavioral differences before and after the use of animal medicines is an important indicator of the efficacy. In order to provide a more fine animal behavior parameters, the movement of the animals in the three-dimensional space in recent years is a hot spot. Animal three-dimensional motion gesture estimate is generally implemented with a multi-view camera. Because the number of model animals and many experiments are required, animals and different experimental designs of different species often need different multi-angle camera framework schemes. But no matter which multi-view camera framework scheme, you need to calibrate the multi-view camera.[0003]The existing multi-camera calibrati...
