The Catalogue of Stereo-Pairs Images as a Simulation Development Tool

During development of the passive optoelectronic rangefinder (POERF), its simulation model enacts an important role. The key part of algorithm for a range measurement by POERF is the disparity estimation of images T'1 and T'2 of a target point T from the stereo pair images. Specific conditions of this task do not allow using commonly published algorithms for the solution of stereo-correspondence problem without substantial modifications. Simultaneously, readily available databases of reference stereo-pair images (as for example Middlebury Stereo Database) are not proper for requisite simulation experiments. In this regards, we were obliged to create own database -- the Catalogue of Targets (with stereo-pairs images of selected convenient objects) and an appropriate simulation testing software -- the program RAWd is. The paper deals especially with the problem of sufficiently accurate conversion of a well specified slant range DT0 of a target point T to the corresponding reference disparity value. Consequently, appropriate slant ranges DT can be associated with finding disparities in the given stereo-pair images.
