| Abstract: | On the background of 3D model retrieva1 based on design sketch,a novel approach for vanishing points detection and camera calibration is proposed.Firstly,the advantages and disadvantages of existing vanishing points detection algorithms are analyzed,and a novel overall optimization approach to detect vanishing points of design sketch is presented.Secondly,after camera calibration technologies are explained,an improved linear calibration method is proposed,which is fast and efficient for camera calibration. |
