Image processing computer system for photogrammetric analytical measurement

An image processing method for a photogrammetric analytical measurement in which a survey map is produced based on plural pictures under a common three-dimensional coordinate system defined on a target, said method comprising the steps of:

• rearranging said pictures to select plural pairs of pictures from among said pictures such that each pair of pictures is fixed to produce a survey map section under a picture-arranging system;
• successively connecting said plural pair pictures to each other in a predetermined order under a picture-connecting system;
• displaying a scene, including a pair-picture-display area and a map-production-display area, on a monitor;
• selectively displaying said plural pairs of pictures on said pair-picture-display area under a first monitor controller;
• indicating a pair of object points corresponding to each other on two pictures in each pair displayed on said pair-picture-display area, using an object-point indicator;
• calculating three-dimensional coordinates of an object point represented by the pair of object points indicated by said object-point indicator, using a calculator;
• projecting the calculated three-dimensional coordinates on a plane defined by two coordinate axes of said three-dimensional coordinate system, using a projector;
• and
• displaying the projected three-dimensional coordinates as a point representing said object point concerned on said map-producing-display area, under control of a second monitor controller.

A memory medium storing an image processing program for a photogrammetric analytical measurement in which a survey map is produced based on plural pictures under a common three-dimensional coordinate system defined on a target, said program comprising the steps of:
