中文简介:
本文提出了一种从滚动快门(RS)摄像机整流视频序列的方法。与先前的RS整流尝试相反,我们将失真模型化为由相机的3D运动引起的。摄像机运动被参数化为连续曲线,每帧的最后一行有结。求解曲线参数以使用从KLT跟踪器获得的帧间对应的非线性最小二乘法。我们已生成具有相关基础事实的合成RS序列以允许受控评估。使用这些序列,我们证明我们的算法改进了两个以前发布的方法。 RS数据集可在Web上获得,以便与其他方法进行比较。
课程简介: This paper presents a method for rectifying video sequences from rolling shutter (RS) cameras. In contrast to previous RS rectification attempts we model distortions as being caused by the 3D motion of the camera. The camera motion is parametrised as a continuous curve, with knots at the last row of each frame. Curve parameters are solved for using non-linear least squares over inter-frame correspondences obtained from a KLT tracker. We have generated synthetic RS sequences with associated ground-truth to allow controlled evaluation. Using these sequences, we demonstrate that our algorithm improves over to two previously published methods. The RS dataset is available on the web to allow comparison with other methods.
