These peaks are found by a 3D reconstruction algorithm that takes into account the Poisson statistics of the photon-count data, while promoting spatial smoothness in the reconstructed point clouds. In a previous post, I presented an algorithm that can find multiple peaks per pixel in a matter ... WebThe derived depths were validated by the bathymetric data acquired by spaceborne photon-counting lidar ICESat-2, which was able to penetrate clean shallow waters for sufficient bottom detection. The predicted bottom depth showed good agreement with the true depth, and large-scale mapping compensated for the limitations resulting from along ...
