The present study aims at developing a 3-D trajectory measurement system for birds (in particular endangered species, e.g. raptorial) flying around wind turbines as a part of its complete system to be applied for prevention from bird strike. The method is based on stereoscopic photography which is similar to 3-D particle tracking velocimetry. For stabilizing the bird-image detection performance, time differential technique is proposed and examined considering the influences of hour and weather. All tests are conducted at Hokkaido University firm. For the demonstration purpose, 3-D trajectories of crows above the firm are obtained and shown in order to assess the effectiveness of stereoscopic photography.
