3D Maps Representation Using GNG

Table 3

RMS deviation error (meters) is obtained using different detector-descriptor combinations. Combinations are computed on the original point cloud (raw) and different filtered point clouds using voxel grid and the proposed GNG method. Keypoint detector search radius is equal to 0.05 meters. Feature extractor search radius is equal to 0.02 meters.
