Study Introduces New LiDAR Signal Denoising Method

To find the most suitable denoising method for LiDAR signals, a study published in Sensors compared various single and joint denoising algorithms. The result indicates that the WT-VMD joint algorithm has the best noise reduction effect, the highest signal-to-noise ratio, and can increase LiDAR signal inversion accuracy.
