Inspection and Orientation Model of Digital Camera

According to the collection and pretreatment of the graphics information, algorithm of Canny is used to determine the pixel coordinates of the all centers, the target picture coordinates and the relative positions of the two cameras. So the positioning model of the digital camera is built. The precision and stability of the model are tested by using the average relative precision and the overall conservation degree. The results indicate that the average precision and the overall conservation degree of the model maintain a higher degree.
