Abstract

The invention discloses the microscopic field-of-view digital expansion method of a microscopic vision system based on a computer microscopic vision slice scanning technology. The method comprises thefollowing steps of firstly, making the microscopic vision system move along the X and Y axis directions of a defined coordinate system in a plane vertical to an optical axis through a precision positioning system, carrying out slice scanning on the clear imaging space of a focal plane position, acquiring the multiple partial field slice scanning images of the clear imaging space of the focal plane position, and recording the displacement of the precision positioning system; and then, constructing a three-dimensional slice field of view space through using a two-dimensional slice scanning image and combining with the depth of field of the microscopic vision system, and using rasterization and raster numerical technologies to carry out digitization on a three-dimensional slice space so asto obtain three-dimensional slice field of view space digital information; and finally, using the digital information of the three-dimensional slice field of view space to reconstruct the microscopicfield of view digital information of the expanded microscopic vision system. By using method, the microscopic field of view space information of a micro-assembly system with a high resolution, a largefield of view, and digitization can be simultaneously acquired.

Description

technical field [0001] The invention belongs to the field of intelligent manufacturing and scientific research, specifically serves the field of micro-assembly and micro-operation, and specifically relates to microscopic visual observation technology, especially the design of microscopic visual space containing multiple same-scale or multi-scale ultra-field parts, etc. . 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 magnification of the microscopic vision system according to the size of different objects to obtain the corresponding field of view and resolution. This 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 ...
