| Outline of Final Research Achievements |
Kinematic studies of primate locomotion have suffered from two difficulties: 1) it is almost impossible to attach markers to freely moving animals; 2) it is often difficult to calibrate the space used by the animals. We propose a solution based on SfM 3D photogrammetry. This technique is widely used for still images but we expanded its use to video clips. We filmed animals using 4-8 synchronized cameras. The film streams were converted into sequentially numbered JPEG images. For each frame set we applied the open-source tools Bundler and PMSV to generate a 3D point cloud representing the animal’s body surface. In test sessions, we analyzed various locomotor behaviors of the Japanese macaques and chimpanzees. The results showed that the method works well and generates 3D reconstructed body surface data during locomotion. The accuracy was much better than that of the manual digitization. Our new technique provides a powerful new tool for kinematic analysis outside the laboratory.
