Abstract
A structured light projector and a method for structured light projection are disclosed. The structured light projector includes a projection module, an image sensor and a processor. The projection module is configured to project an optical pattern onto a region of space. The image sensor is configured to capture an image by detecting the optical pattern projected onto the region of space. The processor is configured to calculate disparity information of the optical pattern projected onto the region of space from the captured image, and is configured to compensate for the disparity of depending on an environment temperature of the projection module.
