In order to meet real-time requirements of strip surface defect detection, the extracted 41 original features of strip surface defects are reduced-dimensionally optimized through the principal component analysis. As the study samples of improved BP neural network, the 10 integrated features are used to train and test network. The trained network model is saved for on-line recognition and classification...
Moving object detection and tracking is the base of the soccer robot system. Kalman filter has been used in the estimation of the positions of moving object in soccer robot system. Because of the maneuverability of soccer robot and the uncertainty of the prior estimate of noise, estimation of kalman filter is divergent. Adaptive kalman filter can adjust the parameters of model on line, to get accurate...
Detection of strip surface defects target is the focus and difficulty of Strip surface quality inspection system. Aimed at the problem resulting from uneven illumination and slowly-changing global illumination in the strip test site, the background difference algorithm is adopted in strip surface defect detection. Firstly normal strip surface image as the initial background is fast reconstructed through...
A novel control scheme for binocular robotic visual tracking problem is proposed. First we obtain the parallel configuration using rotation matrix and translational vector which can be both derived by corresponding points. Second, the binocular vision system provide the position in space and the references are used to estimate the transformation matrix to predict the image motion of the virtually...
