[0040] refer to figure 1 Shown, the first embodiment of the present invention, the present invention proposes a kind of laser detection method, and described detection method comprises the following steps:

[0041] In step S10, the laser is controlled to emit laser light, which is projected to form a laser imaging area.

[0042] That is to say, the laser projected by the laser is planar, and the projection screen occupies a certain area. The laser generally refers to the infrared laser used for ranging in the depth camera, and the laser emitted by the infrared laser is projected on the white board. A laser imaging area is formed. After the laser forms an image on the white board, the light is reflected and shoots to the camera, wherein a brightness acceptance area is also included in the laser imaging area, and the imaging brightness of the brightness acceptance area generally conforms to Acceptable standards, where the standard is set by the user according to the needs of th...

Abstract

The invention discloses a laser detection method, device, equipment and a depth camera. The detection method includes the following steps: controlling the laser to emit laser light and projecting to form a laser imaging area; controlling the camera to photograph the laser imaging area to obtain display image, the shooting area of ​​the camera is larger than the laser imaging area, the part of the laser imaging area corresponding to the displayed image is an imaging picture, and the part of the shooting area corresponding to the display image is a shooting picture; According to the imaging picture, the number of pixels conforming to the standard brightness value occupies the pixel ratio of the shooting picture; according to the imaging picture, the projection angle of the laser is obtained; the laser is judged by the pixel ratio and the projection angle Eligibility. The technical solution of the invention can detect the laser before it is assembled into a finished product, thereby effectively improving the detection efficiency.

Description

technical field [0001] The invention relates to the technical field of laser detection, in particular to a laser detection method, device, equipment and depth camera. Background technique [0002] When manufacturing products with lasers, it is often necessary to assemble the lasers into finished products, and then test various parameters of the finished products, such as the divergence angle of the laser, etc. The process of assembling the finished products is time-consuming, laborious, and inefficient, so it is difficult to judge quickly Whether the laser complies with the standard of use. Contents of the invention [0003] The main purpose of the present invention is to provide a laser detection method, device, equipment and depth camera, aiming to solve the problem of the existing technical solutions. After the laser is assembled into a finished product, the detection of the laser is time-consuming, laborious, inefficient, and difficult to quickly judge. The question o...
