基于SLM显微立体视觉模型的3D微定位研究

Study on Three-Dimensional Micro Motion Positioning Based on a Micro Stereovision Model of Stereo Light Microscope

基于体视显微镜(Stereolightmicroscope,SLM)的显微立体视觉已经在微操作领域应用。本文研究了基于SLM显微立体视觉模型的微操作系统中的三维微观定位问题。通过对SLM双光路的分析,给出了描述二维图像空间和三维物空间映射的弱非线性显微立体视觉模型。采用立体匹配算法和目标识别两种方式对运动图像序列中的目标对象进行捕捉,可以批量给出立体图像中相关点的坐标。利用显微立体视觉理论模型和显微图像处理实现了微操作系统中的微观3D定位。

Micro stereovision with a stereo light microscope is applied in the area of micromanipulation.In this paper,three-dimensional motion positioning in micromanipulation system based on a micro stereovision model of stereo light microscope is studied.Via the analysis of optical paths of stereo light microscope,a weak non-linear model of micro stereovision describing the projecting relation from two-dimensional space to three-dimensional space is derived.Using the stereo match algorithms and object recognition capture the objects in stereo moving image serials,and a great deal of image coordinates of matched points is extracted.So three-dimensional micro positioning is ensured using the micro stereovision model and image process in micromanipulation system.
