Method and system for digital extension of microscopic depth of field in microscopic vision system

Abstract

The invention discloses a microscopic vision system microscopic depth of field digital expansion method and system based on a computer microscopic vision tomography technology. The microscopic visionsystem microscopic depth of field digital expansion method based on a computer microscopic vision tomography technology includes the steps: obtaining a tomographic image through the computer micro-visual tomography technique, and acquiring a three-dimensional tomographic field of view space corresponding to the tomographic image by combining the tomographic image with the step size of a precise positioning system; reconstructing the three-dimensional tomographic space digitized information by means of rasterization, digitization and other technologies; and finally, acquiring a digital microscopic field of view space with an expanded depth of field extension according to all the obtained digitized information of the tomographic space and tomographic space positional information, and then realizing expansion of the depth of field. The microscopic vision system microscopic depth of field digital expansion method based on a computer microscopic vision tomography technology overcomes the contradiction between high resolution and large depth of field, breaks through the limitation of being unable to obtain the ultra depth of field spatial information accurately because of the small depthof field of the microscopic vision system, and represents the microscopic vision field spatial information of the a micro assembly system with a large depth of field by means of the digitized information, thus visually and vividly representing the three-dimensional object information of the microscopic vision field space with the super depth of field.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing and scientific research, specifically serves the fields of micro-assembly and micro-operation, specifically relates to microscopic vision technology, and especially relates to the observation and operation of cross-scale objects in the microscopic viewing field space. Background technique [0002] The microscopic vision system is the key equipment for observing tiny parts, tiny objects, and cells. In order to be able to clearly observe the global shape information of objects of different sizes, it is necessary to adjust the depth of field of the microscopic vision system according to the size of different objects, which increases the difficulty of operation and reduces the observation accuracy of the microscopic vision system. Under high resolution and high magnification, the microscopic vision system can see small objects clearly, but the inverse relationship between resolution and depth ...
