  • Method, apparatus, and device for determining spectral reflection
    Patent number: 12579691
    Abstract: A method includes: obtaining a registration depth map and a target spectral image; obtaining depth information of a target point from the registration depth map, and obtaining a first grayscale value of the target point; calculating 3D coordinate information of the target point according to the depth information of the target point, a first internal parameter of the imaging spectrum device, and first coordinate information of the target point in the target spectral image; determining normal vector information corresponding to the target point according to neighboring points of the target point; inputting the 3D coordinate information and the normal vector information into a full-light model of a diffuse reflecting plate to obtain a second grayscale value; and obtaining reflectance of the diffuse reflecting plate, and calculating reflectance of the target point according to the reflectance of the diffuse reflecting plate, the first grayscale value, and the second grayscale value.
