A Super-resolution Digital Slice Scanning Method Based on Area Scan Camera

Abstract

The invention relates to a super-resolution digital slice scanning method based on an area array camera, which relates to the technical field of slice scanning. The present invention comprises the following steps: the first step: scan the slice into several pictures, and divide each picture into at least 4 areas equidistantly; Take pictures of the whole picture in the first area, then move the distance of one area and take pictures of the whole picture again; move the pictures in turn until all the areas are moved; the third step: for the results of the second step above, Find the same photos in each area; Step 4: For the same low-resolution image obtained in the same area, use super-resolution technology to reconstruct the high-resolution image of this area; Step 5: End the continuous motion, that is, realize A column of data in the same direction is scanned and reconstructed. The invention achieves the purpose of obtaining high-resolution images under the condition of fast scanning.

Description

technical field [0001] The present invention relates to the technical field of slice scanning. Background technique [0002] Digital slice (i.e. virtual slice) is not a static picture, it contains all lesion information on the glass slice, this digital slice (ultra-large space, high-resolution picture) can be arbitrarily enlarged and reduced on the computer, and sliced Any position on the glass slice can be observed by using the digital slice, and the corresponding position can be magnified to 5 times, 10 times, 20 times, 40 times, just like zooming in and out on a microscope. At present, there are two ways to scan digital slices; 1. The traditional way is to assemble a high-resolution CCD camera on the microscope to take pictures, so that the high-magnification glass slice images are partially photographed multiple times, and finally generated The N multiple pictures are combined into a whole slice image using the software function of the computer, thus completing the prod...

Problems solved by technology

[0003] Traditional digital slice scanning has the following disadvantages: 1. Slice scanning requires high magnification and high resolution, and the effective sample area collected by a single field of view of the camera is limited; 2. A slice requires thousands of single-view images to be stitched together, and the probability of misspelling High; 3. The single shooting area is small and the scanning time is relatively long
