专利汇可以提供Photogrammetric apparatus专利检索，专利查询，专利分析的服务。并且Photogrammetric apparatus wherein a pair of stereophotographs have their images projected into the apparatus''s optical system so as to form a stereomodel therein, which is visually observable through the optical system''s binocular viewer. Relative movement of the optical system''s measuring markers and the stereomodel is detected by moving a scanner device over the planar surface of a grid device, which serves as an encoder and develops command signals corresponding to the coordinates of a selected relative position of the scanner device and the grid device. A computer then from the command signals develop control signals for casing a servo system to move the stereophotographs so that the markers and the stereomodel assume a relative position corresponding to the coordinates selected by the scanner device. The scanner device can also simultaneously plot a reproduction of the contour of the stereomodel being traced in any desired scale. Additionally, an XY plotter or coordinatograph can plot another reproduction of the same contour in a still different scale.，下面是Photogrammetric apparatus专利的具体信息内容。
