MOBILE PHONE PHOTOGRAMMETRY. Geometric & radiometric evaluation of mobile phone & still video camera

What is it about?

This paper examines the potential of mobile phones to be used as front-end sensors for photogrammetric procedures and applications. For this purpose, two mobile phone cameras (Sony Ericsson K750i and Nokia N93) were calibrated over an indoor 3D testfield, using a self-calibrating bundle adjustment.

Why is it important?

Geometric accuracy tests were carried out in order to evaluate their metric performances and to compare the results with respect to two off-the-shelf digital still video cameras (Sony DSC W100 and Sony DSC F828). The geometric accuracy evaluation comprised an absolute accuracy test, JPEG test and temporal stability test. The radiometric capabilities of all cameras (except that the DSC W100 was replaced with a DSC T100 camera) were also evaluated and compared by carrying out modulation transfer function (MTF) analysis, image noise analysis and an operating range test.

Substantial systematic errors were diagnosed in some systems. It is believed that with a proper calibration and data processing software performance these devices can be used for many photogrammetric tasks that require an accuracy of around 1:10 000.
