Outline of Final Research Achievements |
In this study, we devised an algorithm that estimates the ego-motion of a small unmanned aerial vehicle by classifying optical flow (OF) patterns, inspired by insect’s visuomotor control system. We also implemented the algorithm in a small circuit system composed of a CMOS image sensor and an FPGA, and tested the performance of the system in motion. The results showed that the system estimated the actual ego-motion properly.

Academic Significance and Societal Importance of the Research Achievements |
本研究で取り組んだような動画像処理を,従来のコンピュータを用いてドローンの制御が行える速度で行うことは容易ではない.本研究では,このような処理を効率よく行っている視覚神経系のアルゴリズムとアーキテクチャを手本として,ディジタル回路を用いて視覚情報を並列に処理することにより,実用的かつ低消費電力なシステムを実現した.この成果は,小型・高速・低消費電力なシステムでの画像処理を必要とする他の応用でも生かすことができる.
