| Abstract: | For acquiring precision product CAD model in reverse engineering,we must accomplish space pionts matching, the paper described the relations between the object space points and image space points by establishing the vidicon model.the rules for laser stripe matching is presented based on the epipolar constraint and continuity constraint.A new solving the point of curve and line matching method is proposed,then realized fast precise matching of laser stripe and 3D reconstruction of laser scanning line. |
