Recently, pixel numbers and functions of consumer grade digital cameras are amazingly increasing by modern semiconductor and digital technology, and there are many low-priced consumer grade digital cameras which have more than 10 mega pixels on the market in Japan. For example, 14.7 Mega consumer grade digital cameras have already appeared on the market in 2008.
In these circumstances, convenient digital photogrammetry using consumer grade digital cameras are enormously expected in various application fields. There is a large body of literature and software on the calibration of consumer grade digital cameras. However, there are still problems for efficient digital photogrammetry using consumer grade digital cameras. These problems are performance evaluation of consumer grade digital cameras from the view point of stability, reliability, robustness of housing and physical integrity of the camera, and evaluation of repeated utilization of interior orientation parameters which was obtained beforehand.
With this motive, performance evaluations of consumer grade digital cameras are investigated in this paper with respect to stability, reliability, robustness and issue for repeated utilization of interior orientation parameters using 50 consumer grade digital cameras.
