Three dimensional digitizers with high resolution

Abstract EN

This paper presents a new approach for image digitizing in the Cartizian three dimension XYZ coordinates.

It is defined as the displacement vector concept based on the hierarchical stereo vision technique depending on multi camera system, distributed around the tested object.

Optical sensors without any mechanical parts under the control of a host computer with an integrated full automatic calibration process are introduced.

Problems of this automated style are investigated.

Different factors such as calibration, feature extraction, point to point correspondence, determination of cartizian coordinates, transformation into symbolic computer aided design form are included.

Performance of the proposed system is analyzed and results of the application to a human foot model as a sample of testing are determined.

The execution time and effort are dramatically decreased with increased measured accuracy.
