| 摘 要： | 在视觉测量、摄像机标定和三维重建等领域中，单应矩阵的估计都起着至关重要的作用。用平面模板代替传统的传感器进行视觉测量和摄像机标定，由于其成本低，操作快速简单等优点，已经得到了越来越广泛的应用。文中主要讨论了二维成像平面的透视投影模型，给出了一种最大似然估计法获取平面模板与成像平面的单应矩阵的求解过程，并用Levenberg-Marqurdt算法对结果进行非线性优化。该方法简单、快速、易实现，在计算机视觉应用中具有一定的理论意义和应用价值。

| Abstract: | Homography plays an important role in visual metrology,camera calibration and 3D reconstruction under both theoretical and practical standpoints.Planar pattern instead of the traditional sensor conduct visual metrology and camera calibration,because of its low cost,quick and simple operation,etc.,has been more and more widely used.This paper discusses the model of 2D planar projective transform and proposes a solution procedure of acquiring planar pattern and the homography matrix of imaging planar using th... |
