Problems solved by technology

In the process of finding the focus, if the judgment is made according to the entire moving distance of the scanner's Z axis, the field of view to be judged is too much and the speed is too slow; if the search is made according to a selected moving range, there is a possibility of losing the focus, resulting in image out of focus

Abstract

The invention discloses a method for focusing a camera image in a digital slice scanner. The method comprises the following steps: 1, obtaining a navigation preview image of a slice and identifying and obtaining a scanning area; 2, dividing all scanning visual fields in the scanning area; 3, selecting a focussed visual field and a coarse focusing visual field; 4, focusing the coarse focusing visual field; 5, expanding the field focus of the coarse focusing field into the focusing field; 6, finely focusing the focusing visual field; 7, setting focus values of all visual field according to the distances from the visual fields to the focused visual field. The method has high stepping focusing speed, an image focus can be accurately found, the method is used for a full-automatic digital pathological scanner, and the problem of image defocusing in an existing camera image focusing technology is solved.

Description

technical field [0001] The invention relates to a camera image focusing method in a digital slice scanner, belonging to the technical field of image processing. Background technique [0002] Pathological examination is a pathological and morphological method used to examine pathological changes in body organs, tissues or cells. In order to explore the disease process of organs, tissues or cells, digital pathological slide scanners can be used to examine the pathological morphological examination of their lesions, and discuss the causes, pathogenesis, and development of lesions. process, and finally make a pathological diagnosis and pathological morphological examination. [0003] The digital pathology slide scanner combines the micro-optical magnification system and computer technology to scan and collect images of traditional pathological glass slices one by one, and splicing and merging each pair of images to form a high-resolution, full-information digital pathology sli...
