Embodiment Construction
[0023] In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the embodiments and accompanying drawings, and the contents mentioned in the embodiments are not intended to limit the present invention.
[0024] refer to figure 1 Shown, a kind of multi-channel video image splicing method of the present invention, the steps are as follows:
[0025] (1) Acquire the image data of each video at the same moment, and stitch the images, and calculate the pixel coordinate position mapping transformation matrix from the original image to the spliced image and the mask matrix (mask matrix) for pixel value transformation;
[0026] The calculation of the pixel coordinate position mapping transformation matrix is specifically: use the accelerated robust feature (SURF) algorithm to obtain image feature points, and eliminate the feature points in non-image overlapping areas; use the nearest neighbor and...
