This work is based on the cells in the microinjection system to process adherent cells image. Performing low-pass filtering to the Image of adherent cells, removing uneven illumination, segmenting foreground and background, removing invalid small areas, operating opening and closing operation, keeping the target area, calibrating centers of the cells in the original image.
This paper presents a camera calibration method that could be used in humanoid robot vision system. Extended Kalman filter is used to estimate camera parameters. This method can take planer board feature points of the image or the object's 3D axis as inputs when doing known motion, test results show this algorithm can get good results. If the camera parameters are known, the relationship between a...
