3DPIXA: Limitations of block-matching algorithms on depth reconstruction

Thursday, 9. January 2020

This white paper gives a comprehensive overview on the limitations of the block-matching approach in height reconstruction for passive stereoscopy. It describes a variety of different artefacts that appear at certain image features. The occurrence of the artefacts is explained by means of the algorithms underlying mathematical model which is introduced in the first chapter. Images captured with a 3DPIXA exemplify the visual appearance. Additionally, we use simulated stereo images where appropriate to illustrate the difference between the calculated height and the ground truth from simulation.
