Abstract

The invention provides a multi-station detection device for a structured light projection module. The multi-station detection device comprises a plurality of detection mechanisms, a multi-station transmission mechanism and a plurality of projection module fixators; at least one detection mechanism comprises a camera and a target plate, wherein the camera is suitable for photographing a pattern projected on the target plate by the structured light projection module; the multi-station transmission mechanism comprises a transmission mechanism which is separated from the detection mechanisms; theprojection module fixators are fixed to the transmission mechanism and can move along with the transmission mechanism; and the projection module fixators are distributed at different positions of thetransmission mechanism; and each projection module fixator is suitable for being driven by the transmission mechanism to move to a test station corresponding to any detection mechanism. The inventionfurther provides a detection method of the multi-station detection device for the structured light projection module. With the multi-station detection device and the detection method of the inventionadopted, rapid detection of various test items of the structured light projection module can be realized.

Description

technical field [0001] The invention relates to the field of optical technology, in particular, the invention relates to a structured light projection module multi-station detection device and a detection method thereof. Background technique [0002] The structured light projection module is used to project a structured light pattern outward, which is an important part of realizing 3D imaging. Speckle structured light is currently a relatively mature solution for projecting structured patterns. Its projection module mainly includes a projection module light source component (VCSEL) and a lens component. The lens component specifically includes a collimator element and an optical diffraction element. . The speckle pattern projected by the projection module, the number and brightness of the light spots, and the angle of view will all affect the quality and accuracy of imaging. Improving the intensity and quantity of the light source components of the projection module can im...
