Abstract

The invention relates to a microscopic sequence image splicing method and device, and the method comprises the steps: employing a template matching algorithm to match overlapped regions of adjacent images, and calculating the position difference of the adjacent images; And establishing a mathematical model according to the adjacent relation between the images, and calculating global position coordinates of the images by combining a BP algorithm to generate a global image. According to the method, mismatching caused by blank or repeated areas and the like of the images in the local splicing process can be effectively processed, mismatching of local splicing is reduced, and high robustness is achieved; And the calculation speed is high, the automation degree is high, and the splicing effectis 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...
