Paper Abstract

In this paper, we concerns on the location of the micro manipulator in a micro manipulating system based on SLM and two CCDs. After getting the depth image of an object and its background by SLM, we stress the importance on how to separate them and then obtain the position information of the object. Firstly, we obtain HSI model of the micro-vision image according to the transform function from RGB to HSI. Then, we draw the curve of H component of the image. According to this image, we separate the object from the background successfully. After that, applying moment method, we calculate mass centric coordinate of the object. Finally, applying the projective geometry in the stereo vision, we get centric coordinate of the object combined with the coordinate system of the CCD. Therefore, we realize the location of the micro object. This method is applied in practical micro-manipulating and fast and high-accurate location of object is obtained with a locating accuracy less than 1%.
