Abstract

The embodiment of the application provides a test model construction method and device and an optical center test method and device of a depth-of-field module. According to the test model constructionmethod, a polynomial curve characterizing the depth test capability of a depth-of-field module is determined; on the basis of the polynomial curve, a three-dimensional polynomial curved surface is generated; and a three-dimensional test model formed by the three-dimensional polynomial curved surface is obtained, wherein the three-dimensional test model is used for reflecting infrared laser transmitted by the depth-of-field module to the depth-of-field module and thus the depth-of-field module obtains depth information of the three-dimensional test model, and the optical center of the depth-of-field module is determined based on a depth-of-field image generated based on the depth information. Therefore, the influence by an external light source is avoided; and thus the test accuracy of thetest result is improved.

Description

technical field [0001] The embodiments of the present application relate to the field of camera lens technology, and in particular to a method for constructing a test model, a method and equipment for testing the optical center of a depth-of-field module. Background technique [0002] The depth-of-field camera module can collect the depth information of the target object in the real world to obtain the depth-of-field image of the target object, and realize a more realistic and higher-quality image description of the real world. Among them, the optical center is an important parameter of the depth of field module. Based on the optical center of the depth of field module, it can be judged whether the position of each component of the camera module is shifted or tilted, and the position of each component of the depth of field module can be determined based on the optical center. Make corrections. [0003] The position of the optical center of the depth of field module can be d...
