Therefore, building up a health monitoring system can significantly lower the maintenance cost and workload. With cow behavior recognition, the health status of dairy cows can be monitored. In this research, we developed a dairy cow behavior recognition system to monitor dairy cows' health status. Six main behaviors were classified: lying, standing, walking, drinking, feeding and ruminating. For data collection, a 9-axis inertial measurement unit (IMU) was equipped on each cow to continuously collect raw motion data. Our IMU device would then send the raw data through the internet to our backend computer for further analysis. To label the IMU data for dairy cow behavior recognition, four cameras with different angles were set up in the experimental dairy farm to simultaneously record videos of different cows. All behavior types were then labeled manually into the IMU data by watching the recorded video. These IMU data were then processed and used to build the behavior recognition model. Four data processing steps were included in this research: selecting different window sizes, feature extraction, features selection, and normalization. Various model structures including SVM, Random Forest and XGBoost were also tested to yield the best model for recognizing cow behaviors. The behavior recognition results could be further analyzed for health status monitoring, such as low ruminating time or long lying time that could be utilized for estrus detection or calving. |
