摘要： PROBLEM TO BE SOLVED: To implement real-time processing of mobile motion estimation in simple hardware configuration.SOLUTION: For each of reflection point coordinates for one scan of a laser sequentially held in a register B, a differential from each of a plurality of reflection point coordinates held in registers A0-A63 is computed and a moving vector is outputted by each of a plurality of computing elements 20. For each of the moving vectors outputted from the plurality of computing elements 20, a counter C to count a frequency of the moving vector is designated by each of a plurality of decoders 22. Thus, frequencies of a plurality of values relating to the moving vectors for one scan of the laser are counted by counters C0-C255. A counter C counting a maximum frequency is identified by a comparator tree 24, and a moving vector corresponding to the counter C identified by the comparator tree 24 is outputted as a present vehicle motion estimation result by an output section 26.
