Convenient 3D measurement using consumer grade digital camera is enormously expected in various fields with appearance of the low cost and high-resolution consumer grade digital cameras. In these circumstances, the authors have been concentrating on developing convenient 3D measurement system which is Image Based Integrated Measurement system called as IBIM system. The device of IBIM system consists of a consumer grade digital camera and laser distance meter. The most remarkable point of the system was its ability to calculate exterior orientation parameters and interior orientation parameters and pseudo GCPs without using scale bar or GCPs in object field. However, there were still issues which are labor and time consuming in distance measurement and deterioration of image quality.
In order to achieve more convenient 3D measurement, the IBIM system is improved using triplet images of multiple cameras of different resolutions and bundle of distances. This paper describes camera calibration techniques and its evaluations using images of multiple cameras of different resolutions and bundle of distances.
