Comparative analysis of Full Frame and APS-C camera sensors on 3D digitization results

Image based 3D digitization methods, as an input data, use a digital photographs for reconstruction of 3D objects. Today, digital cameras are common devices used for capturing of digital photographs. Every digital camera is equipped with one of two types of digital sensors — CCD or CMOS. One of important features of these both types of sensors is their physical size. This paper presents results of comparative analysis regarding the influence of Full Frame and APS-C sensor size on 3D digitization results obtained with photogrammetric Structure from Motion (SfM) method. Comparative analysis also included influence from obtained data on accuracy with the use of auto calibrated andpre-calibratedphotographs.
