A multi-scale focus pseudo omni-directional robot vision system with intelligent image grabbers

In this paper, the development of an intelligent image grabber and its application to a multi-scale focus pseudo omni-directional robot vision system is presented. The new developed intelligent image grabber is designed using DSP and FPGA technology, which can do both the task of image grabbing and the task of image processing. A pseudo omni-directional robot vision system, which can "see" the four directions simultaneously using 4 sets of intelligent image grabbers and cameras, is realized and a multi-scale focus strategy which can improve the efficiency of this pseudo omni-direction robot vision system is also proposed. Experimental results have shown that this pseudo omni-directional robot vision system can work quite well
