The invention discloses a video splicing device and method, comprising: a camera device for shooting images to be spliced; a planar sensor for sensing the moving track of the video splicing device on a horizontal plane; a memory for storing multiple instructions, and the instructions are applicable The processor is loaded and executed; and the processor is used to implement various instructions; the multiple instructions include: receiving the first image to be stitched and the second image to be stitched successively taken by the camera device and finding the center position thereof; acquiring the planar sensor to upload track of movement; judge whether the image unit where the center position of the first image to be stitched appears in the second image to be stitched, if so, according to the moving track of the video stitching device and the image unit where the center position of the first image to be stitched is in the second image to be stitched The position in the image determines the overlapping area; and then quickly completes the stitching of the first image to be stitched and the second image to be stitched according to the overlapping area, which is simple and convenient.
Description
technical field [0001] The present invention relates to the technical field of image processing, in particular to a video splicing device and method. Background technique [0002] There are many methods of image stitching, and different algorithm steps will have certain differences, but the general process is the same. Generally speaking, image stitching mainly includes the following steps: [0003] 1) Image preprocessing, including basic operations of digital image processing (such as denoising, edge extraction, histogram processing, etc.), establishing image matching templates, and performing certain transformations on images (such as Fourier transform, wavelet transform, etc.) Waiting for operation; [0004] 2) Image registration, in simple terms, is to use a certain matching strategy to find out the corresponding position of the template or feature point in the image to be stitched in the reference image, and then determine the transformation relationship between the t...
