System will be used for video based 3D tracking to analyze visual and odour guided insect behaviour in a wind tunnel. The system must accommodate recording of relevant flight parameters in low light conditions. The system must have a high accuracy and resolution. In addition to analysis of flight trajectories in relation to the odour plume, the system must accommodate analysis of relative and absolute flight speed, distance, turn angles and heading. The system must be easily calibrated, and installation and customer support must be included. Easy visualization flight tracks and play back must be supported.
