Performance detection method and detection system of tof module

Abstract

A detection method and detection system for the performance of a TOF module, the detection method obtains a first test value and a second test value based on the light intensity value and depth value corresponding to each frame of image acquired by the TOF module to be tested , the third test value, the fourth test value, the fifth test value, the sixth test value, the seventh test value; the first test value, the second test value, the third test value, the fourth test value, the seventh test value Add the fifth test value, the sixth test value and the seventh test value to obtain the evaluation value; judge whether the performance of the TOF module to be tested is qualified or not by the size of the evaluation value. Through the detection method, the performance of the TOF module to be tested can be comprehensively detected, the precision and accuracy of the performance detection of the TOF module can be improved, and the efficiency of the performance detection of the TOF module can be improved.

Description

technical field [0001] The invention relates to the technical field of TOF, in particular to a performance detection method and a detection system of a TOF module. Background technique [0002] TOF (Time-Of-Flight) technology has a long history, but with the rapid development and application of intelligent technology and virtual reality technology in recent years, TOF technology and TOF modules have been greatly developed, becoming a new technology in today's imaging technology field. Research hotspots, with high research value and broad application prospects. [0003] The module based on TOF technology is a new type of miniaturized three-dimensional imaging device, which can capture the grayscale image and depth information of dynamic targets at the same time, thus easily solving the traditional problems in the field of machine vision. Using these depth information can not only easily Complete traditional applications such as segmentation, labeling, recognition, and tracki...

AI Technical Summary

Problems solved by technology

[0005] During the design process or after the assembly of the TOF module, the performance of the TOF module needs to be tested, but the existing tests are all performed manually or for specific one or more performances, and the detection efficiency is low. And the performance test of the TOF module is not comprehensive
