چکیده

In many applications, denoising is necessary since point-sampled models obtained by laser scanners with insufficient precision. An algorithm for point-sampled surface is presented, which combines fuzzy c-means clustering with mean shift filtering algorithm. By using fuzzy c-means clustering, the largescale noise is deleted and a part of small-scale noise also is smooth. The cluster centers are regarded as the new points. After acquiring new point sets being less noisy, the remains noise is smooth by mean shift method. Experimental results demonstrate that the algorithm can produce a more accurate point-sample model efficiently while having better feature preservation.

Terrestrial Laser Scanner Point Cloud Denoising by Range Image Nlmeans Processing for Small-sized Objects

In some applications, long range operations Terrestrial Laser Scanners (TLS) achieve insufficient precision: for instance, a decorated façade will not be modeled correctly with the point cloud obtained by TLS. It may be necessary, in such cases, to combine different acquisition techniques to deal with the large size of the object to model and its fine details. Hence, data denoising in the conte...
