Abstract

The present invention relates to a microsequence image mosaic method and device, the method comprising: using a template matching algorithm to match overlapping regions of adjacent images, calculating the position difference of the adjacent images; establishing a mathematical model according to the adjacency relationship between the images , combined with the BP algorithm to calculate the global position coordinates of the image to generate a global image. The present invention can effectively deal with the error matching caused by blank or repeated regions in the image in the process of partial splicing, reduces the error matching of partial splicing, and has high robustness; moreover, the calculation speed is fast, the degree of automation is high, and the splicing The effect is good.

Description

technical field [0001] The invention relates to the field of image processing, in particular to a method and device for splicing microscopic sequence images. Background technique [0002] Image stitching is the process of synthesizing multiple partially overlapping images collected by imaging equipment into a large-format, high-resolution image. It can effectively overcome the limitation of the field of view of ordinary imaging equipment, and obtain higher resolution and larger field of view than a single image. Therefore, image stitching has always been an important research topic in the field of image processing and computer vision, and has been widely used in photogrammetry, remote sensing image analysis, medical imaging and video surveillance. [0003] Microscopes (including electron microscopes and optical microscopes), as an instrument for observing the microscopic appearance of the sample surface, have the characteristics of wide magnification range and high resoluti...
