Classification: CPC G | IPC G

Claim 10:
11. The electronic device of claim 8, wherein the processor performs alignment processing on each color image and each depth image to obtain the aligned image by:
obtaining depth pixel points of the depth image;
multiplying the depth pixel points by a first matrix to obtain depth coordinates of the depth pixel points in a depth camera coordinate system;
multiplying the depth coordinates of the depth pixel points by a second matrix to obtain world coordinates of the depth pixel points in a world coordinate system;
multiplying the world coordinates of the depth pixel points by a third matrix to obtain color coordinates of the depth pixel points in a color camera coordinate system;
multiplying the color coordinates of the depth pixel points by a fourth matrix to obtain pixel points of the depth pixel points in the color image; and
obtaining the alignment image according to the pixel points of the depth pixel points in the color image.
