In this paper, we proposed an indirect method to measure the distance of an object accurately by single visual cameras using triangulation. The object can be seen as the third point of a triangle with two known sides and one known angle. Distance to object can be determined indirectly on the base of known sides and angle, rather than being measured directly. It would be very useful in case there is...
In this study, we propose a novel and efficient method to generate 3D-look shade illustrations from simple sketches having outlines and hatching strokes. The basic idea is to use the contours and hatching strokes specified by a designer as a metaphor for constructing a normal field for 3D-look shading effects. The overall shape of a 3D object is depicted with contours, such as silhouette contours...
