- Abstract:
- A method for the reconstruction of a 3D shape is described and applied to a practical measurement case. Multiple stereo systems are employed to measure a 3D surface with superimposed colored markers. The described procedure comprises a detailed uncertainty analysis of all the measurement phases, and a statistical compatibility analysis of the colored markers measured by different stereo pairs. The compatible acquired markers are statistically merged in order to obtain a measurement of a 3D shape and an evaluation of the associated uncertainty. The obtained results show that the selected experimental set-up allows to considerably reduce the uncertainty associated to the fused points. The selection of a limit distance, that divides compatible points from not compatible ones, is also presented.
