Problems solved by technology

[0003]Because of the difference in photographing methods between line array cameras and area array cameras, the photosensitive chips of area array cameras are arranged in a matrix. For scattered images, a specific algorithm is required to calculate two-dimensional coordinates, while the current line array camera algorithm can only calculate one-dimensional coordinates, which is not suitable for splicing pictures taken by the opposite camera

Abstract

The invention provides an algorithm for splicing area-array camera pictures. The algorithm comprises the following steps of calculating the overlapping area of each sub-picture in a to-be-processed image, setting a mark according to the overlapping area, and solving a default value of each column of sub-pictures according to the overlapping area. Changing the marks of the sub-images according to the comparison result of the overlapping area of each sub-image and the default value of the corresponding column, adjusting the overlapping area of each sub-image according to the marks, and finally splicing all the sub-images to form a spliced whole image. According to the method, the discrete sub-images in the to-be-processed image are effectively spliced, the problem of area-array camera imagesplicing is effectively solved, the discrete adjacent images can be perfectly connected, and the finally obtained spliced whole image is continuous, seamlessly connected and not repeated, and the calculation efficiency is high.

Description

technical field [0001] The invention relates to the field of image stitching, in particular to an algorithm for image stitching of an area array camera. Background technique [0002] At present, most scanners on the market use line cameras to scan slices, and line cameras are a special type of vision machine. At present, there is no shortage of wired camera stitching algorithms, which can stitch multiple columns of long strip images scanned by the line camera into a whole picture. In the process of mosaic, only the situation between the columns and the columns need to be considered, as long as the left and right are stitched together. Combine multiple columns of graphs into a complete large graph. [0003] Due to the different ways of taking pictures between line array cameras and area array cameras, the photosensitive chips of area array cameras are arranged in a matrix. Currently, the linear camera algorithm can only calculate one-dimensional coordinates, and is not suit...
