  5. ISPRS WG V/4 Terms of Reference ” Integration of Image analysis and spatial information systems for applications in cultural heritage”.

  6. For the Goal of This Terms of Reference Algorithm or System for low-cost photogrammetry using Amateur Camera should be developed.

  7. Appearance of Low-Cost System

  8. Software for Low-cost Digital Photogrammetry Software for Low-cost Digital Photogrammery is designed to perform convenient 3D measurements using amateur digital camera. Software was named “3DiVision” with key words; 3Dimension; Digital image; Visualization.
