| Abstract: | For the design and development of a vision sensor for the ground test,a method of 3D reconstruction of feature point on large scale object surface from a single image is proposed.By establishing the math model of the 3D coordinate of feature point on the object surface and using the spatial ray through feature point,the 3D coordinate of the feature point can be determined using single image.According to the characteristics,the object surface can be classified into three types: high order surface type,block ... |
