-A new approach based on BP neural network for seeking-solution projection matrix of camera is presented in this thesis. The network structure is designed according to camera mathematical model, where there are 4 inputs composed of the sampled points’ coordinates in world coordinate system and constant 1, and 2 outputs are obtained, expected values of which(More)
A new approach for binocular vision system calibration and 3D re-construction is proposed. While the system is calibrated, the sum of square distances between the vector coordinates recombined with the coordinates of feature points in the world frame and those in image frame to the fitted hyperplane is taken as an objective function. An orthogonal learning(More)
Original scientific paper As the basic part of the mechanical transmission, gears should have high transmission accuracy, so the gear’s precision measurement is a key technology. Based on the existing research, the computer vision technology is introduced in gear test. According to the definitions of technical indexes, such as pitch deviation, tooth(More)
