The rabbit’s claw toe surface was reconstructed by intersecting lines and point cloud fitting respectively,and the error was analyzed.The results show that the maximum deviation of the surface obtained by the first method is 0.254 mm,and the maximum deviation of the latter is 0.341 mm.The intersection line surface is more suitable for the reconstruction of complex surface such as claw toe.Based on the surface constructed by intersecting lines,the ridge and front contour of claw toe with special structure are extracted.The correlation coefficients of ridg...
