The embodiment of the present application relates to the technical field of computer vision, and discloses a DOE shedding detection method, device, electronic equipment, and storage medium. The method includes: acquiring a speckle image captured by a camera to be detected on a target plane; performing global binarization on the speckle image to obtain the binarized speckle image; A unit, performing a morphological closing operation on the binarized speckle image to obtain the morphologically closed speckle image; determining a target area in the morphologically closed speckle image, and determining the The number of target areas and the number of pixels in each of the target areas; according to the number of the target areas and the number of pixels in each of the target areas, it is determined whether the DOE of the camera to be detected falls off. The DOE shedding detection method provided in the embodiment of the present application can enhance the robustness and universality of the detection, judge whether the DOE is shedding in time, and avoid human eye damage caused by the DOE shedding to the greatest extent.
Description
technical field [0001] The embodiments of the present application relate to the technical field of computer vision, and in particular to a DOE drop detection method, device, electronic equipment and storage medium. Background technique [0002] A structured light camera is a camera that emits an active infrared light source and obtains depth data through calculation. The structured light camera is widely used in three-dimensional application scenarios, the most typical one is the application of three-dimensional face recognition. The principle of the camera shows that the infrared speckle captured by the structured light camera is obtained by the laser emitting device through the diffractive optical element (Diffractive Optical Elements, referred to as: DOE). In addition to generating various types of speckle, the DOE It can also weaken the intensity of the infrared laser and protect the human eyes. However, DOE is usually fixed inside the structured light camera by glue. Th...
