Accurate 3D geometry measurement for non-cooperative spacecraft with an unfocused light-field camera
文献摘要：
This work explores an alternative 3D geometry mea-surement method for non-cooperative spacecraft guiding navig-ation and proximity operations.From one snapshot of an un-focused light-field camera,the 3D point cloud of a non-coope-rative spacecraft can be calculated from sub-aperture images with the epipolar plane image(EPI)based light-field rendering al-gorithm.A Chang'e-3 model(7.2 cm×5.6 cm×7.0 cm)is tested to validate the proposed technique.Three measurement dis-tances(1.0 m,1.2 m,1.5 m)are considered to simulate different approaching stages.Measuring errors are quantified by compar-ing the light-field camera data with a high precision commercial laser scanner.The mean error distance for the three cases are 0.837 mm,0.743 mm,and 0.973 mm respectively,indicating that the method can well reconstruct 3D geometry of a non-coope-rative spacecraft with a densely distributed 3D point cloud and is thus promising in space-related missions.
