Cubic Range Error Model for Stereo Vision with Illuminators [article]

Marius Huber, Timo Hinzmann, Roland Siegwart, Larry H. Matthies
2018 arXiv   pre-print
We show that the range error for stereo systems with integrated illuminators is cubic and validate the proposed model experimentally with an off-the-shelf structured light stereo system.  ...  Among others, this is the case for structured light stereo systems and night stereo systems with headlights.  ...  Passive stereo range error model We will first revisit the quadratic error model for passive stereo, taking into account radiometry, before we consider how it changes for active stereo. 1) Incident light  ...

Fusion of time-of-flight depth and stereo for high accuracy depth maps

Jiejie Zhu, Liang Wang, Ruigang Yang, James Davis
2008 2008 IEEE Conference on Computer Vision and Pattern Recognition  
Time-of-flight range sensors have error characteristics which are complementary to passive stereo.  ...  In contrast, these sensors are noisy and often perform poorly on the textured scenes for which stereo excels.  ...  Laser scanners are too slow for real time use. Passive stereo fails on textureless scenes. Time-of-flight sensors are low resolution, noisy, and poorly calibrated.  ...
