Abstract
A convenient 3D measurement using amateur digital camera is enormously expected from various fields according to appearance of the high resolution amateur digital cameras since pixel numbers of amateur digital cameras are amazingly increasing by modern semiconductor and digital technology. In these circumstances, software for low-cost digital photogrammetry“3DiVision”was designed to perform convenient 3D measurement using amateur digital cameras. However, there are problems for efficient digital photogrammetry using amateur digital camera. These problems are distance measurement and preliminary interior orientation, and these restrictions should be removed for ideal convenient photogrammetry.
With this objective, composite photogrammetric device was developed by the authors consisting of 5 parts : mirrors, an amateur digital camera, a laser range finder, a personal computer and a monitor. The most remarkable point of this system is its ability to calculate orientation parameters without scale distance or GCP in an object field. This paper describes the composite photogrammetric device and its performance evaluation.
