Development of Image Based Integrated System and Application to Non-Contact 3D Measurement

Abstract

Convenient 3D measurements using consumer grade digital cameras are enormously expected in various fields with appearance of low cost and high resolution consumer grade digital cameras. In these circumstances, software for digital photogrammetry“3DiVision”was designed to perform convenient 3D measurement using consumer grade digital cameras. However, there are still problems for efficient digital photogrammetry. These problems include distance measurement for absolute orientation and previous interior orientation procedure, and these restrictions should be removed for ideal convenient photogrammetry using digital cameras.
With this objective, integrated sensor with CCD and laser called as Image Based Integrated Measurement (IBIM) system was developed by the authors. The most remarkable point of the system is its ability to calculate both of exterior and interior orientation parameters without scale distance or ground control points which have exact 3D coordinates in object field. This paper focuses the IBIM system and its performance evaluations. Furthermore adaptability of this system to 3D modeling of topography and historical structures in architecture and archaeology are discussed from the view point of 3D noncontact measurement.
