Example Embodiment
[0032] The embodiments of the present invention will be described in detail below. It should be emphasized that the following description is only exemplary, and is not intended to limit the scope of the present invention and its application.
[0033] figure 1 It is a schematic diagram of a structured light depth camera according to an embodiment of the present invention. The depth camera includes a structured light projection module 10 and a collection module 20. The structured light projection module 10 is used to project structured light beams into space. When the structured light beams irradiate the plane 60, structured light will be generated on the area 30 Pattern 50, the collection module 20 is used to collect structured light images on objects in its collection area 40. Generally, the projection area 30 is not smaller than the collection area 40 to ensure that the objects in the collection area corresponding to the collection module can be structured Covered by light patt...
