Assessment of Iterative Closest Point Registration Accuracy for Different Phantom Surfaces Captured by an Optical 3D Sensor in Radiotherapy

Figure 4

Residuals of surface pairs shifted by in direction of the studied phantoms captured by the optical sensor AlginRT and aligned by the Wilm approach.

(a) Plane: all residuals are below

(b) 3plane: problems at edges and tilted planes

(c) Bowl: problems at sloping surface parts

(d) Torso: holes at stitching area of the two sensors
