Problems solved by technology

This method is complex and difficult to implement
Another method is to achieve automatic focusing through the sharpness and edge characteristics of the focal plane image and the non-focal plane image, such as using the absolute variance function, the plane differential square sum function, the gray gradient operator function, the gray difference method, Evaluation functions such as energy spectrum function, wavelet transform, Roberts operator, Laplacian operator, etc. This method requires high hardware processing speed, so its further development has certain limitations

Abstract

The invention discloses a method for realizing programmable control of software imaging. The method comprises the following steps of adopting a CCD (Charge Coupled Device) camera to collect an optical image of software imaging in real time, adopting a video signal module to convert the collected optical image to a video signal of an analog image, and meanwhile, carrying out line frame separation on the optical image collected by the CCD camera to complete line synchronization and line frame synchronization; adopting a band-pass filter to filter high-frequency noise of the video signal and a low-frequency signal; adopting an A / D converter to convert the filtered video analog signal to a video digital signal to carry out data processing; and driving a rotating direction of a step motor through a CPLD (Complex Programmable Logic Device) module according to the received video digital signal under the control of line synchronization and frame synchronization to change a focal length of the CCD camera so as to obtain a clear image and realize programmable control of software imaging.

Description

technical field [0001] The invention relates to a programmable control method, in particular to a control method capable of realizing software graphic programming, and belongs to the field of programmable control. Background technique [0002] Microscopes are widely used in various fields and are a common optical instrument. The development of instrument automation and intelligence has put forward higher requirements for the degree of automation of the microscope, and there is an urgent need for fully automatic control of the microscope system in applications. The core part of the automatic control microscope system is the autofocus technology, so how to effectively realize the autofocus of the microscope has become a key issue to improve the performance of the microanalysis system and realize high-precision measurement. [0003] Microscope focusing methods can be divided into two categories: one is laser confocal method. It uses the laser beam to form a point light source...
