5. 线段裁剪和多边形裁剪算法的动画演示实现。(两种线段裁剪算法和H-S多边形逐边裁剪算法)多边形裁剪算法的动画演示要求先画出一个封闭的多边形,再画矩形的裁剪窗口,然后选择裁剪按钮(或命令),按下“上边裁剪”按钮(或执行“上边裁剪”命令),多边形相对裁剪窗口的上边进行裁剪,显示上边裁剪后的多边形,依此进行其它各边裁剪。
6. 两种扫描多边形扫描转换算法实现(扫描线算法为必做,基于求余运算的边缘填充和边标志算法任选一种);
7. 4连通区域的递归种子填充算法,和扫描线种子填充算法,要求种子点(x,y)可交互输入)。

Description: 如何由非定标序列图象计算出相机和景物的度量特性是相机自定标技术要解决的主要问题。相机定标方法是利用景物的已知三维点坐标或几何特性,如正交方向的灭点等,
确定相机的定标矩阵K,而相机自定标方法是直接根据图象和相机内外参数的约束来确定相机和景物的度量特性。相机定标对于计算机视觉的许多应用来说是非常重要,而在实际应用中,定标过程往往是很复杂的,因而,在过去的几年中,许多学者在相机自定标方面做了大量的工作,其研究结果表明,对于刚性景物来说,相机自定标是可行的。本文给出了一种新的基于线性模型摄像机的相机自定标方法。该方法是首先利用三点透视投影图、灭点和向量正交的性质来得到一组非线性方程,然后将其转换为线性方程组,以避免求解过程中的累积误差,最后高精度地求出了全部内参0 0 , ,u ,v x y a a 。实验结果表明,此方法是有效的。-err
