Sketch map of the method of LRF construction. The blue point and black points denote the keypoint p and neighboring points qi within the neighborhood with support radius r, respectively. The orange plane denotes the projective plane perpendicular to Z-axis. The blue, red, and green arrows denote the Z-axis of LRF, vectors from p to qi, and the vector projecting to plane L
