A grassland rodent burrow identification method based on UAV aerial photography and machine learning is proposed. First, a UAV is used to photograph the survey area to obtain high- and low-altitude images. Then, the high-altitude images are pre-processed using the coordinates of ground control points to obtain the corresponding DOM (Domain Image) images. Next, both the DOM and low-altitude images undergo color space transformation and multi-scale segmentation to obtain corresponding high- and low-altitude polygon images. The low-altitude polygon images are then divided into training and validation samples. The algorithm classifier is repeatedly trained and validated using these samples until the required accuracy is achieved, resulting in a mature algorithm classifier. Finally, the high-altitude polygon images are fed into the algorithm classifier to output the vector data of the rodent burrow polygons. This design not only offers good accuracy and low time consumption but also boasts high recognition speed and strong timeliness, making it suitable for precise dynamic monitoring and prediction of rodent distribution.
