Abstract

The invention provides a three-dimensional target which comprises a target body, the target body is provided with a test surface, the test surface is provided with a test area, the test area is provided with at least three test blocks arranged in a central radial mode, and a gap is formed between any two adjacent test blocks. The resolution of the three-dimensional camera module is continuously tested through the radially arranged test blocks, and the test accuracy is improved. The invention also provides a detection device and a detection method.

Description

technical field [0001] The present application relates to the technical field of optical testing, in particular to a three-dimensional target, a detection device and a detection method. Background technique [0002] In recent years, with the gradual popularization of electronic devices such as portable mobile phones, tablet computers, and notebook computers, users have higher and higher requirements for the experience of electronic devices, especially the 3D camera module that can obtain a better camera experience. [0003] In the field of stereoscopic machine vision, the imaging resolution and accuracy of the equipment are important indicators for assessing the quality of the imaging system and image imaging quality, directly affecting the accuracy of the final measurement results, so it is necessary to use testing instruments to measure the resolution and accuracy objectively However, in the process of implementing this application, the applicant found that there are at le...
