Abstract:Infrared camera is an important method in the investigation and monitoring of wildlife resources, but the processes of massive image data and species identification are time‑consuming and laborious. Infrared camera is unable to automatically identify target species along with large amount of image data, cumbersome manual retrieval, and low detection efficiency and identification accuracy of convolution neural network. To solve these problems, this study proposed an object detection method embedding attention mechanism by using Chinese monal (Lophophorus lhuysii) as model. A total of 110 000 images were collected by infrared cameras, and 715 images were selected for further analysis. The results showed that the accuracy of the proposed network could achieve 99.62%. The improved method can improve the efficiency of species identification, reduce labor costs, and promote the protection of target species.
