According to appearance of low cost and high resolution digital cameras with various functions, a convenient 3D measurement using the digital cameras are enormously expected in various fields. In these circumstances, the authors have been concentrating on developing a convenient 3D measurement method using the digital cameras. Software “3DiVision” has been designed to perform convenient 3D measurement under the key words ; 3Dimension, Digital image and Visualization, and “3DiVision” shown the capability to perform camera calibration without GCPs and subsequent 3D measurement.
However, there is still issue for realize a convenient digital close range photogrammetry. The main problem is robust calibration procedure for triplet images which are taken at various distances from camera to object and ill-balance exposure stations. In order to resolve the issue, robust camera calibration method which is able to accomplish a convenient digital close range photogrammetry using triplet images of ununiform photo scales and ill-balance exposure stations are proposed in this paper.
