| 摘 要： | 现今的三维重建技术大多要从多幅图像中找到对应特征,进而求解基本矩阵,然而照片越多就意味着要付出更多采集和计算的时间及空间,对减少图像的幅数而实现同样的三维重建效果将具备一定研究价值。利用霍夫线检测、角点检测、边缘检测等算法,提出一种基于单张照片的三维重建新方法,通过霍夫变换在二值图像取线,再利用OpenCV获取方块的角点数等信息,得到图像基本轮廓,最后透视变换得到图像贴图,并利用画坐标的方法模糊定义模型的参数对应于图像参数的关系,从而实现三维重建。该方法被应用于列车车体的三维重构实验中,实验结果证明了该重建方法的可实现性,也揭示了其工程应用价值。

| Abstract: | 3D reconstruction technique has been widely applied in the field of industries. it needs many pictures to find out the corresponding characteristics, and then Currently solve the fundamental matrix. As a result, the more pictures are needed, the more collection time and calculation cost must be paid, and a 3D reconstruction technique with the requirement of fewer pictures is always desirable. A method of 3D reconstruction based upon a single picture, by using the algorithms of reference line detection, corner detection and edge detection, is described in this paper. The method is employed in train 3D reconstruction, and the test results are provided and show the method is effective. |
