photogrammetric method of photogrammetric image processing apparatus, using the photogrammetric image processing apparatus, and storage medium storing the photogrammetric image processing program

摘要

PROBLEM TO BE SOLVED: To quickly make a survey drawing and easily detect the falsification of a digital image in an image processor for photographic surveying capable of making the survey drawing with the digital image.;SOLUTION: This image processing unit for photographic surveying displays a first image IM1 and a second image IM2 on an image display area IMA of a monitoring image plane. Both images IM1, IM2 include the same object and target 10 placed on a target position RP1. A first image point AQ11 as an image point of a surveying point q1 in the first image IM1 is manually specified. An auxiliary line ADL is displayed on the second image IM2 on the basis of two-dimensional coordinates of the first image point AQ11, and the camera data and the target data stored in an IC memory card for both of the first and second images IM1, IM2. The no-falsification is judged when the second image point AQl2 is manually specified, and a distance between the second image point and the auxiliary line ADL is less than a predetermined value, and the surveying point q1 is displayed on a drawing area DRA.;COPYRIGHT: (C)2001,JPO
