Abstract:
A photogrammetric image processing apparatus defining a plurality of images commonly including a target at a predetermined position as being in the same group, calculating the camera position of the photographing camera taking each image and the inclination of its optical axis for each image, designating a common physical point in each image, calculating three-dimensional coordinates of the physical point, and generating a survey map based on the three-dimensional coordinates, comprising:a display processor that has a image display area for displaying all of said images belonging to the same group, and a drawing area for displaying said survey map; an area computing processor that calculates a valid mapping range of the same group, which is shown in said drawing area, based on the camera position and the optical axis inclination; and a control processor that displays images of a predetermined group in said image display area, and displays said valid mapping range of said predetermined group in said drawing area.
