形状和表面颜色是表征真实物体属性的两个要素.随着三维扫描技术的发展,获取精确稠密的三维数据已经 比较容易.通过对获取的三维数据做相关处理,就能够生成正确表达物体形状的几何模型,但仅仅如此还不足以精 确建模真实物体.为了建立照片真实感的三维模型,还需要将物体的表面颜色和几何模型融合.如果彩色相机和三 维扫描仪固定在一起,这个问题很容易解决.但是,这种固定采集方式在应用时很不方便,对采集数据限制很大,因 此需要将三维数据和彩色图片采集分开进行,通过后期合成方式来融合两种数据.(err)

在各种图形中，通过提取点的凹凸部分来鉴别曲线的特征，本节代码利用曲率关系分别提取凹点的个数，判断曲线的弯曲(In a variety of graphics, through the extraction point to identify curves convex-concave part of the characteristics of the code used in this section were extracted from concave curvature of the relationship between the number of points to determine the bending curve)

在P4P问题中,当空间4个点共面时,不仅摄像机坐标系与物体坐标系之间 的旋转矩阵R和平移向量t可以线性求解,而且可以同时确定摄像机的有效焦距f和像素比例，该程序设计模拟已知相机矩阵M情况下由已知三维空间点和图像坐标情况求解相机外参数矩阵(When space four points coplanar P4P problem, not only between the camera coordinate system and the object coordinate system rotation matrix R and translation vector t Can be solved linearly, and can determine the camera s effective focal length f and pixel ratio, the program is designed to simulate a known camera matrix M Camera outside the parameters matrix case solved by the known three-dimensional space points and image coordinates)
