The authors have been concentrating on developing convenient 3D measurement methods using consumer grade digital cameras, and it was concluded that consumer grade digital cameras are expected to become a useful photogrammetric device for the various close range application fields. On the other hand, mobile phone cameras which have 10 Mpixel were appeared on the market in June, 2009. In these circumstances, convenient 3D measurement using mobile phone cameras are enormously expected in various photogrammetric fields instead of consumer grade digital cameras.
With this motive, accuracy aspects of mobile phone cameras are investigated in this paper with respect to lens distortion, stability, reliability, robustness and practicability. The calibration tests for 17 mobile phone cameras (1.3M×1, 2M×6, 3M×4, 5M×3, 8M×2, 10M×1) are conducted using test target indoor and practicability is evaluated at outdoor. This paper presents that mobile phone cameras have ability to take the place of consumer grade digital cameras, and develop the market in digital photogrammetric fields.
