Double-camera calibration clamp, equipment and method

Abstract

The embodiment of the invention relates to the field of double-camera testing, and discloses a double-camera calibration clamp, equipment and method. In the invention, the double-camera calibration clamp comprises a calibration graph fixing mechanism which is provided with at least two stations used for fixing different calibration graphs; a clamp body which is used for fixing the to-be-calibratedproduct in a manner that the center connecting line of the main camera and the auxiliary camera on the to-be-calibrated product is parallel to each station; a calibration point is arranged on the calibration graph fixed by each station, and the distances from each calibration point to the central point of the main camera are equal; a driving mechanism connected with the clamp body; and a main control unit electrically connected with the driving mechanism. Compared with the prior art, a plurality of calibration parameters of the double cameras can be completed in the same area, the calibrationsteps are simplified, the operation is simple, the test efficiency is improved, and the calibration test of the double cameras is more stable.

Description

technical field [0001] Embodiments of the present invention relate to the field of dual-camera testing, and in particular, to a calibration fixture, device and method for dual-cameras. Background technique [0002] Existing electronic products such as mobile phones and tablets are generally equipped with a main camera and an auxiliary camera. When shooting, the auxiliary camera assists the main camera to shoot together to capture a more realistic image. When the main camera and the auxiliary camera are produced and applied to electronic products, the parameters such as reference gain, exposure time parameters, and photographing accuracy of the two cameras need to be tested first to ensure that the cameras can be used normally in electronic products. [0003] When the dual cameras on existing products need to be calibrated and tested to obtain various parameters, three stations need to be set up. Different calibration diagrams are placed on each station. The UDCF calibration ...

Problems solved by technology

[0004] Through the above-mentioned dual-camera calibration process, the inventor found that the entire calibration test needs three stations to complete, and the three test fixtures occupy a large space in the production line, and the personnel are cumbersome to operate, and frequently move the product to be tested, which also leads to test efficiency and test stability. poor sex
