Embodiment Construction

[0025] The specific implementation of the TOF camera stray light detection device and detection method thereof provided by the present invention will be described in detail below in conjunction with the accompanying drawings.

[0026] Please refer to figure 1 , is a schematic structural diagram of a TOF camera stray light detection device according to a specific embodiment of the present invention.

[0027] The stray light detection device includes: a fixed position 101 and a reflective mirror 102 .

[0028] The fixing position 101 is used to fix the TOF camera to be tested. The TOF camera to be tested has multiple modules such as a lens module, a light source module, and a sensor. The fixing position 101 may include a fixing bracket, which is convenient for placing the TOF camera. figure 1 In the figure, the fixed position 101 is only used as a schematic position, and does not represent the actual structure of the fixed position 101 . The specific structure of the fixing ...

Abstract

The invention relates to a TOF camera stray light detection device and a detection method thereof. The TOF camera stray light detection device comprises a fixed position and a reflecting mirror. The fixed position is used for fixing the TOF camera to be detected; and the reflecting mirror faces the fixed position, and the reflecting surface of the mirror face is in an arc shape back to a fixed position bulge. The TOF camera stray light detection device and the detection method thereof can improve the accuracy of TOF camera stray light detection.

Description

technical field [0001] The invention relates to the field of sensing technology, in particular to a TOF camera stray light detection device and a detection method thereof. Background technique [0002] TOF camera is composed of several units such as light source, optical components, sensor, control circuit and processing circuit. After the TOF camera lens is assembled, due to the surface roughness of the assembly materials used, the reflection and refraction of light between materials and materials, the mutual matching of various material parts, assembly procedures, and assembly effects, etc. Stray light not estimated by design. [0003] For TOF cameras, active light detection is used. At present, the detection light used by TOF cameras is in the near-infrared band, which cannot be recognized by the human eye; and the detection of stray light needs to simulate a strong light environment. The strong light in the near-infrared band is invisible, but it is easy to cause damag...
