Image registration method and system and image shooting alignment method and system

Abstract

The invention relates to an image registration method and system and an image shooting alignment method and system. The image registration method comprises steps that the feature area in a first imageis projected multiple times to the search area in a second image, the feature area projected in the second image each time defines a matching area, the feature area of the first image comprises multiple first target points, the first target points projected to the matching areas are defined as first target centers, and the search area of the second image comprises multiple second target points; the second target point closest to each of the first target centers in the matching areas is sequentially searched, the distance between each of the first target centers and the closest second target point is defined as a target offset value, the sum of all the target center offset values in the matching areas is defined as a registration value of the matching areas; the matching area with the smallest registration value in the search area is acquired as the feature registration area, a displacement difference between the feature area of the first image and the feature registration area of thesecond image is calculated as the registration offset for registration of the first image and the second image. The method is advantaged in that calculation is relatively fast.

Description

technical field [0001] The present invention relates to the field of gene sequencing, and more specifically, the present invention relates to an image registration method and system, and an image shooting alignment method and system using the image registration method and system. Background technique [0002] In the field of gene sequencing, image capture and identification of samples are usually required. Since the observation range of the lens of the capture device is much smaller than the area of ​​the sample, the lens can only capture a part of the sample each time. The existing technology usually adopts a continuous stepping method to sequentially capture multiple small areas that fit the observation range of the imaging device. During subsequent data processing, it is necessary to register images of the same small area captured at different times to obtain gene sequencing. As a result of the analysis, the prior art method requires a relatively large amount of calculati...
