【摘要】 文章对基于立体视觉与网格光栅投影的三维表面重建系统及其图像处理中的一部分:图像特征提取进行了介绍。该方法基于立体视觉,结合网格光栅投影,把被动的立体视觉与主动的非结构光光栅投影相结合,为后续的特征提取与立体图像匹配制造了方便。在网格图像的特征提取中,该文根据系统特点及图像特征,采用一种简单的谷底提取算法即可有效实现网格图像的特征线、特征点的提取。更多还原

【Abstract】 A novel system based on the stereo vision to reconstruct the three dimensional surface is present.The system combining the passive binocular vision principle with the active non-structure projection through a grid raster simplifies the successive feature extraction and image matching.Aiming at the special system and its image feature,a valley ex-traction algorithm for the intersectant lines and the crossing points in the grid image are discussed in detail,and the results prove its efficiency.更多还原
