Abstract: Traditional point photogrammetry, line photogrammetry developed in the present and the infinite point theory are synthetized and sublined to the generalized point photogrammetry. After the theory of the generalized point photogrammetry is introduced, its applications are presented, including computer of image parameter from vanishing point and modelling by single image, determination of image parameters by matching between vector and image, inspection of sheet\|metal part and determination of plane pose by contour line matching.
