Document Type and Number:
WIPO Patent Application WO/2020/010829
Kind Code:
A1
Abstract:
A detection method for a laser projector (20), comprising: (01) controlling a laser projector (20) to project laser to a predetermined plane (131); (02) obtaining a laser pattern (30) modulated by the predetermined plane (131); (03) selecting a highlighted region (31) in the laser pattern (30) according to gray-scale information of the laser pattern (30); (04) obtaining the energy of the laser projected by the laser projector (20) into a high-energy region (50) as the detection energy, the high-energy region (50) being a region on the predetermined plane (131) corresponding to the highlighted region (31); and (05) determining whether the projection energy of the laser projector (20) meets the safety standard according to the detection energy.
