[0016] The present invention will be described in detail below in conjunction with the drawings. However, it should be understood that the drawings are only provided for a better understanding of the present invention, and they should not be construed as limiting the present invention.
[0017] Such as figure 1 As shown, the method for extracting forest single tree parameters provided by the present invention includes the following steps:
[0018] 1) Extract the characteristic parameters of the lidar waveform data of the forest, where the characteristic parameters of the lidar waveform data include the leading edge, the trailing edge and the half energy height of the lidar waveform data.
[0019] The lidar waveform data is based on the time difference between the laser pulse recorded by the lidar scanner from launch to return to the receiver, and the distance between the measured object and the lidar scanner is obtained, combined with GPS (Global Positioning System) and IMU (Inertia...
