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

Embodiment Construction

[0013] A super-resolution digital slice scanning method based on an area array camera, characterized in that it comprises the following steps:

[0014] Step 1: Scan the slice into several pictures, and divide each picture into at least 4 regions equidistantly;

[0015] Step 2: Along the direction of the area divided in the first step, the area array camera first takes pictures of the whole picture in the first area, and then moves a distance of one area to take pictures of the whole picture again; move the pictures in turn until it moves Complete all areas;

[0016] Step 3: For the result of taking photos in the second step above, find out the same photos in each area;

[0017] 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;

[0018] Step 5: The continuous motion ends, that is to realize the scanning and reconstruction of a row of data in the same direction.

Abstract

The invention provides a super resolution digital slice scanning method based on an area-array camera, and relates to the technical field of slice scanning. The method comprises the following steps: a first step: scanning a slice into multiple pictures, and at least equidistantly dividing each picture into 4 areas; a second step: shooting an entire picture in a first area along the direction of the areas divided in the first step by the area-array camera, shooting the entire picture again after moving the distance of an area, and sequentially moving to shoot until moving all the areas; a third step: finding identical pictures in each area according to the shooting result in the second step; a fourth step: reconstructing a high resolution image of the area by using the super resolution technology for identical low resolution images in the same area; and a fifth step: terminating the continuous movement to scan and reconstruct a series of data in the same direction. The super resolution digital slice scanning method provided by the invention is used for achieving the purpose of obtaining the high resolution image under a fast scanning condition.

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...
