Embodiment Construction

[0022] The present invention will be further described below in conjunction with embodiment.

[0023] The rapid autofocus method of the microscope in this embodiment includes first controlling the coarse focus screw to drive the stage up and down for coarse adjustment of focus, and then controlling the fine focus screw to drive the stage up and down for fine adjustment of focus.

[0024] Controlling the rough focus helix to drive the stage up and down and the coarse focus adjustment include: first controlling the coarse focus helix to drive the stage up, and then controlling the coarse focus helix to drive the stage down. During the process of rising and falling the stage, the Every time the object stage moves one step, the camera of the microscope collects an image, and the collected image is input into the computer, and the computer intercepts part of the image as the target object for focusing. In this embodiment, only the original image is 1920X1200. The size is 800X600 im...

Abstract

The invention discloses a rapid automatic focusing method of a microscope, which comprises the following steps: firstly controlling a coarse focusing screw to drive an objective table to lift for coarse focus adjustment, and then controlling a fine focusing screw to drive the objective table to lift for fine focus adjustment, and the fine focus adjustment comprises the following steps: 1) taking a focusing distance interval obtained by coarse focus adjustment as a basis, a fine focusing screw is controlled to drive the objective table to ascend and descend in the focusing distance interval, images are collected, the definition of the target object is compared through a Tenenggrad gradient function, the clearest image is selected, and the corresponding optimal position of the objective table is obtained according to the clearest image; 2) verifying the optimal position of the objective table obtained in the step 1); and 3) controlling the fine focusing screw to drive the objective table to move to the optimal position of the objective table from the final staying position. According to the invention, the focusing speed and the focusing precision can be ensured, the microscope focusing can be quickly completed under a high magnification, and the focusing time can be greatly saved.

Description

technical field [0001] The invention relates to the technical field of microscopes, in particular to an automatic focusing method for a microscope. Background technique [0002] When using a microscope to observe the image on the glass slide, it is necessary to adjust the focal length of the microscope to obtain a clear picture. Due to manufacturing and matching precision problems of the existing coarse quasi-focus helix and fine quasi-focus helix that drive the microscope stage up and down, there is a gap between the actual rising or falling distance of the stage and the preset lifting distance when it drives the stage up and down. Deviations, which lead to the failure of the existing microscope automatic focusing method to focus under high-magnification lenses, and manual adjustments are often required to obtain the required clear images. Contents of the invention [0003] In view of this, the purpose of the present invention is to provide a rapid auto-focus method for ...
