Abstract EN
Concealed cars extraction from point clouds data acquired by airborne laser scanning has gained its popularity in recent years.
However, due to the occlusion effect, the number of laser points for concealed cars under trees is not enough.
Thus, the concealed cars extraction is difficult and unreliable.
In this paper, 3D point cloud segmentation and classification approach based on full-waveform LiDAR was presented.
This approach first employed the autocorrelation G coefficient and the echo ratio to determine concealed cars areas.
Then the points in the concealed cars areas were segmented with regard to elevation distribution of concealed cars.
Based on the previous steps, a strategy integrating backscattered waveform features and the view histogram descriptor was developed to train sample data of concealed cars and generate the feature pattern.
Finally concealed cars were classified by pattern matching.
The approach was validated by full-waveform LiDAR data and experimental results demonstrated that the presented approach can extract concealed cars with accuracy more than 78.6% in the experiment areas.
