Abstract: Highlights•A minimum probability random sampling method is designed.•A local multi-dimensional feature fusion module that can capture the point cloud features of bushes is proposed.•The multi-channel attention module was used to learn interactive information between channels.•The algorithm achieves the best balance of accuracy, speed and computational cost.
