- W2366118719 abstract "When solving the problem of digital camera positioning by binocular position, the following two problems should be solved,which included: the coordinates of objects’ feature points on the camera image plane, and the exact relative position of two cameras.When seeking coordinates of the target’s center on the camera image plane, a fenestral imaging model was established with the formulation of the central coordinates determined by the spatial transformation matrix M.Logic operation detecting image edge was used to fit coefficients of elliptic equations by multiple regression, then get the coordinates.Besides, the model was tested by computer simulation, that is add salt and pepper noise and Gaussian noise of different probability densities in the original image, then de-noising by median filtering, the center of coordinates is found.Compared with the original values, the results show that the influence of the salt and pepper noise and Gaussian noise are smaller.Namely, the accuracy of computer simulation is higher and stability is better.When determining the accurate relative position of two cameras, it is assumed that the camera is fixed, first discuss a camera by rotating the object plane, then get the location parameters in the frame of reference.In the same principle, it is also determined that the positional parameters of another camera are set, so the relative position of two cameras is obtained." @default.
