Abstract：The article utilizes image automatic recognition technology and 3D laser point cloud technology to interpret images of grass height and coverage,achieving the conversion of image data into data.Establish the principle of laser radar inversion and apply it to digital elevation models and digital surface models.Compare the lidar inversion results with the standard values.The results showed that the average relative error of grass height inversion was not greater than 8％,and the average relative error of grass coverage inversion was not greater than 6％.The accuracy of grass height and coverage inversion by lidar was relatively high.
