According to appearance of low cost and high resolution consumer grade digital cameras with various functions, convenient 3D measurement using the digital cameras are enormously expected in various fields. However, there are still problems for efficient digital photogrammetry using the cameras. These problems include 3D measurement for ground control point, previous interior orientation procedures and restriction for taking images. These restrictions should be removed for ideal convenient photogrammetry using the digital cameras.
In order to resolve the above problems, efficient camera calibration method which does not need ground control points nor previous interior orientation procedures are proposed in this paper.
