Paper Abstract

In this paper, the imaging principle of Light Detection And Ranging (LIDAR), and, in particular, the effect factors of intensity of return pluses of LIDAR are analyzed in detail. It is shown that, in one scan band, the intensity of LIDAR return pulses is determined by the ground undulation. The distance information of LIDAR can reflect the actual ground situation, and in the paper, the operator of slope is used to describe the ground undulation, which can be calculated based on LIDAR distance information. A new way is put forward to remove the pulse noise of LIDAR intensity image based on orientation gradient of distance image. The experiments prove that the algorithm can not only remove the pulse noise effectively but also preserves the edge information of Intensity Image better.
