摘要

•Developed a LiDAR simulator to mimic LiDAR scanning on virtual 3D canopy.•Coupling the LiDAR simulator with 3D wheat structure model enables to learn the GAI predication model without in-situ measurements.•Validation using in-situ measurements demonstrates that the height profile of point cloud betters GAI estimation under high values.
