Improved tracking strategy with CamShift algorithm

A novel flight simulator is developed which allows insects to fly actively for up to several hours in any horizontal direction, while their fall migratory flight direction can be recorded uninterruptedly. In the process of data collection and process, the CamShift algorithm combined with MFC (Microsoft Foundation Class) were used and virtual trajectory was drawn simultaneously according to the position of the marked point under the environment of Visual C++6.0 plus OpenCV (Open Source Computer Vision Library). Based on mentioned features, the improved object tracking with CamShift algorithm can obtain real-time flight information of higher tracking precision for insects for a certain range of distance and movement rate.
