Important results from the project
The project has contributed to mitigating collisions between bird and wind turbine on a species level, especially in terms of the ability to identify birds in wind farms automatically
Expected long term effects
+The classification of birds required images with bird at short range to perform optimally. +It was clearly demonstrated that classification of bird species is possible using deep learning models. +With higher resolution cameras, the method will provide significant contribution to classify birds in real-time for mitigating collisions between birds and wind turbines.
Approach and implementation
+ A new bird detection model has been developed to deal with false-negatives by using a gigantic detector-YOLOv7E6E at resolution-1280 and false-positive by class filtering. + A significant amount of data has been collected, labeled, processed, and involved in training a more powerful classifier (ResNet18) to perform bird species classification. + Since the distribution of the collected data is long-tailed, new techniques were involved to balance the data during training and eventually achieved better results. + The overall classification accuracy is around 92%.
