Abstract: A novel virtual sensors measurement system useing one high speed camera is proposed for measuring high flapping moving insect. Principales of virtual measuring system and stereo vision are given firstly’ then the reason of measuring moving insect with four virtual sensors is analyzed. At last calibration method based on multi planes is researched for multi vision sensor. Results show that the measuring system is feasible for insect moving measurement and better result is got.

Key words: stereo vision, virtual sensors, insect, three-dimensional shape, motion parameter
