Abstract
:For inspecting the normal direction at the drilling position of aircraft surface，which helped to provide key
information for the automatic drilling and riveting robot to realize the adjustment of tool attitude，a structured light
vision inspection system composed of industrial charge-coupled device(CCD)and cross laser device etc was estab-
lished. In the system，the projection strips on the target surface produced by the cross structured light were captured
by industrial CCD to compute the contour characteristics of the surface through image processing，which could
