Embodiment Construction

[0029] In order to make the object, technical solution and effect of the present invention more clear and definite, the present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0030] Such as Figure 1-3 As shown, a kind of rapid scanning method of cervical exfoliated cell smear provided by the present invention, the method comprises the steps:

[0031] S1. Accurately measure the thickness of the entire sample, and determine the variation range of the thickness; specifically, take pictures of different positions according to a certain arrangement rule, define the z-axis position of the initial position, and then determine the focal length afterwards Use this as a reference point. Manually adjust the focal length of different photos until it is clear to the naked ...

Abstract

The invention provides a rapid scanning method and system for cervical exfoliated cell smears. An area of a cervical exfoliated cell biological sample is set to be in a circular shape, cell scanning without repeating and missing is achieved through sample boundary judgment, the thickness of the smears is detected to formulate the adjusting step size of a microscope, definition judgment is carriedout on up to seven positions in each scanning area, a camera is called for photographing at the position with the highest definition, the cell number is recorded, and the scanning accuracy is achieved; focusing adjustment is made into a pst file, and correcting and editing are facilitated; and the cell number is recorded synchronously in the scanning process, and scanning is stopped after the target number is reached through logical operation. Thus, the speed and accuracy of the scanning process flow are improved.

Description

technical field [0001] The invention belongs to the technical field of machine vision, and in particular relates to a rapid scanning method and system for cervical exfoliated cell smears. Background technique [0002] At present, when performing microscope scanning, scanning and obtaining sample images may require scanning thousands of fields of view to obtain meaningful results. Mr. Wang Jiachuan proposed the theoretical research on automatic focusing based on image processing, but various comprehensive solutions currently on the market have problems such as inaccurate focusing accuracy, system instability, and scanning speed that cannot meet the needs of large hospitals. [0003] In order to solve these problems, on this basis, we have improved the system performance by improving the moving speed of the platform, the fast focusing of the lens and the fast image processing of the algorithm, thereby improving the speed and accuracy of the scanning process. Contents of the ...
