| Outline of Final Research Achievements |
In this research, we attempted to establish a simple and highly accurate delivery prediction technique for breeding cattle using infrared depth sensor camera which could treat 3D information.
The behavior detection accuracy of the infrared depth sensor camera was investigated by comparing with the macroscopic observation data on posture change, tail lifting, bending, rotation, which are indicators of delivery time. In addition, effect of the environmental condition for behavior recording was investigated.
As a result, it was clarified that posture change, bending, rotation behavior before parturition could be detected with very high precision by this sensor camera , but it is clear that the detection precision decreases with the influence of the field angle of the camera and the photographing condition with respect to the tail lifting.
