Abstract

The invention discloses a depth precision testing device and a detection method for a depth device. Aiming at the problem that no specific device and effective, unified and rapid method for depth calibration and depth detection of the depth device in the existing academic circle and industrial circle exist, the following scheme is provided: the device comprises a six-axis platform adjusting assembly, a linear guide rail, a target plate, a reflector and an optical trap, wherein the depth device projects a pattern to the target plate, the pattern is reflected, an internal processor of the depthdevice calculates a depth pattern according to the collected structural optical group to serve as a reference pattern, data information is stored in a register in the processor, calibration of the depth device is completed, calibration result verification is carried out through different relative and absolute distances, calibration data is corrected according to an internal algorithm of the depthdevice, and the process is depth detection. The device is novel in structure, high in automation level and measurement precision, capable of meeting continuously increasing specific depth requirementsand easy and convenient to use.

Description

technical field [0001] The invention relates to the field of depth device testing devices, in particular to a depth precision testing device and a detection method for depth devices. Background technique [0002] With the development of technology, Deepin devices have begun to be widely used in fields such as face technology, intelligent human-computer interaction, robots, 3D reconstruction, AR / VR, and unmanned driving. Deepin devices include many optical modules, such as emission lighting Module (laser, dot matrix projector), photosensitive receiving module (infrared camera), RGB camera, light inlet window, and processor, etc. The depth device is used to obtain the depth pattern and color pattern of the target. It can be a structured light depth camera, a time-of-flight depth camera, a laser radar, etc. The depth device can obtain two-dimensional depth information in real time, so the depth performance calibration of the depth device And testing is especially important. ...
