摘要：This paper examines the potential of mobile phones to be used as a front-end sensor for photogrammetric procedures and applications. For this purpose we are calibrating two mobile phones (Sony Ericsson K750i and Nokia N93) over our indoor 3D testfield, using self-calibration. Using the same testfield we are performing accuracy tests in order to evaluate the metric performance and comparing them with respect to two off-the-shelf digital still video cameras (Sony DSC W100 and Sony DSC F828). In some systems we have diagnosed substantial systematic errors. We find that the JPEG compression does not significantly influence the errors. We are currently also in the process of checking the stability of the interior orientation over time. This paper reports about our experiences in calibration and accuracy validation of mobile phone cameras. We believe that with a proper performance these devices can be used for many photogrammetric tasks in the future
