In order to obtain camera′s projection matrix, while it is calibrated,the sum of square distances from vector coordinates combined with sample points to the hyperplane decided by projective matrix is taken as the objective function.Then a Sanger neural network with lateral connection is designed,where the self-adaptive minor component extracting method is adopted.And taking the eigenvector of minimum eigenvalues as fitted coefficients of the hyperplane,the projective matrix is obtained and the c...
