Array camera module testing method and calibration plate device thereof

Abstract

The invention discloses an array camera module testing method and a calibration plate device thereof. The array camera module testing method comprises the steps: providing a calibration plate image, collected by the array camera module, of a calibration plate device, wherein the calibration plate device is provided with a first calibration pattern and a second calibration pattern, and the first calibration pattern and the second calibration pattern are integrated on the calibration plate device according to a preset mode; identifying the first calibration pattern and the second calibration pattern in the calibration plate image; and obtaining test results of the first camera module and the second camera module of the array camera module based on the first calibration pattern and the secondcalibration pattern in the calibration plate image. Thus, the camera modules of the array camera module can be tested at the same time, and the test efficiency is improved, and the test operation issimplified.

Description

technical field [0001] The invention relates to the field of camera modules, in particular to an array camera module test method and a target device used in the test process. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the camera function of portable electronic devices. Under this background, the array camera module came into being. As the name implies, an array camera module includes two or more camera modules, through the cooperation between two or more camera modules to achieve many special functions, for example, through the cooperation between two camera modules with different equivalent focal lengths Realize special imaging effects such as "optical zoom". [0003] Before the array camera module is put into use, each camera module of the array camera module needs to be tested separately, so as to perform follow-up operations according to the corresponding test results. For example, each ...

AI Technical Summary

Problems solved by technology

[0005] First, the camera modules of the array camera module are tested sequentially, which is inefficient

[0006] Second, since each camera module is tested separately in sequence, it will inevitably cause errors such as inconsistency in the test

Moreover, in the process of adjusting the optical axis of the second camera module, if it is found that the installation position of the first camera module needs to be readjusted, at that time, the test and adjustment of the array camera module will have to start all over again, which is inefficient and trouble

[0009] Fourth, usually the camera modules of the array camera module have different configurations, that is, the equivalent focal lengths of each camera module are different, and the field of view angles are different.

In this way, not only the material is wasted but also the operation of the testing process is complicated
