In this paper, a novel lidar system has been proposed and developed using two low power laser to make horizontal-path laser measurement of vegetation. We focus on the de-noising process of this new sensor by using wavelet analysis, and the experiments have been down to testify this theory, the results also show its validity in active laser detection.

Keywords:Keywords - lidar;Wavelet Transform;De-noising
