游梁式抽油机驴头悬点投影偏差的分析研究 - In the mesh the local geometric and topological property can be clearly described with its adjacent points for a given point . then the delaunay triangulation technique in two dimensions is used to delete and modify the illegal triangles in the resulting mesh
本文采用切平面作为曲面的局部近似，将局部的采样点投影到切平面上，并对投影点集作二维delaunay三角剖分，最后根据投影点上的邻接关系确定三维点之间的连接关系。 - First the sketch / datum plane is fitted by least - square distance , then the extruded direction or axis with the flank points of the cloud is extracted in quadratic paogramming arithmetic , and certain points projected to gain 2d sketched datas . feature points are defined to segment the sketch datas , and the sketch profile is generated by fitting separately the line and circle segment
使用最小二乘方法拟合草图基准平面，采用二次规划方法提取拉伸方向和旋转轴线，然后将数据点投影以获取草图数据，通过栅格划分提取草图边界轮廓数据，再对这些边界数据进行基于特征点的分割，以直线和圆弧段拟合出草图轮廓。 - In this thesis , our research work mainly focuses on the second aspect , including : 1 perfecting the generation algorithms of stereoscopic image and video on the basis of moving flatly , we brought forward the cylindrical projection and spherical projection algorithms , projecting the flat image or video from two viewing points to the cylinder or sphere to get the stereoscopic image or video , and compared these three algorithms based on the theory and practice
本文的工作内容主要集中在第二方面，包括： 1完善了体视生成算法在平移算法的基础上，提出了柱面投影和球面投影算法，把二维平面图像或视频从两个投影点投影到柱面或球面上，以得到体视图像或视频，并在理论上和实际中对各种算法进行了比较。
