Passive optoelectronic rangefinder (POERF), stereoscopic disparity, foreground object, occluded area


The principle of the passive optoelectronic rangefinder (POERF) is known since the second half of the 1950’s. Publications about research and development of POERF do not exist practically. Presumptive causes are presented in this article. We deal with POERF research and development since year 2003. The last fully functional demonstration model is from the year 2009. We present firstly its brief description. In the next part of the article, we briefly specify problems pertinent to a suppression of the influence of stationary foreground objects on the accuracy of ranges measurement. The last part is focused on the problem of tracking moving target. This article deals with principles, which are exploited in individual algorithms. Detailed description of these algorithms requires several separate articles in congruous specialized journals.
