Research on Photogrammetry and 3D Reconstructing System Based on Single Cameras

2D information collected by double cameras can be used to obtain 3D information in the photogrammertric technology based on single cameras.The codedpoints were utilized for pose recovery of a moving camera and the non-coded points were utilized for 3D points reconstruction.The key concerned contents,such as code and decode,calibration of the camera,camera orientating technique,high precise image processing algorithm were discussed.The application confirmed the precision of the algorithm.The experiment shows that the results are accurate and reliable to meet the requirements of reverse engineering applications.
