Optimal discretization for stereo reconstruction

Basu, A., Optimal discretization for stereo reconstruction, Pattern Recognition Letters 13 (1992) 813-820. A significant amount of research has been done on designing sensors for digitizing visual images. Over the years vidicon and CCD technologies have been developed to improve sensor performance. However the problem of how the sensors should be distributed over a two-dimensional array has been largely overlooked. Sensor resolution is often determind by industry and international standards, and has little to do with the problem for which it is being used. In this work we investigate the optimal horizontal and vertical resolution (given the total resolution) for solving the problem of stereo-reconstruction. We show that the best arrangement of sensor elements depends on both the parameters of a stereo system and the assumptions on the 3-D scene,
