查询词典 homography

Transformed by the corresponding Homography, each pixel in each frame can find its match in the subsequent frame if it occurs in the shared view of these two frames.

实验结果表明，该方法能有效地在摄像机运动环境中进行像素点级别的背景建模。

This thesis also researches following topics, such as the usage of the homography matrix, the method to solve the over-determined linear equition set, the improved 8-point algorithm and some image processing techniques. We conduct some preliminary experiments to applys above technique to broadcasting of sports events, and some preliminary resulted are presented also.

论文所研究的其他内容还包括使用单应性矩阵寻找平面的对应关系，超定方程组的求解，改进的8点法求解基础矩阵以及一些图像处理技术的应用，并将这种生成虚拟图像的技术应用到体育比赛转播中去进行了初步的尝试和探索。

An infinity homography for an image pair within an image sequence is transferred to other image pairs within the image sequence utilizing point matches for the subject image pairs.

图像序列内的一个像对的无穷远单应矩阵利用对象像对的点匹配被传送到该图像序列内的其它像对。

Recently, a linear algorithm of projective reconstruction based on the homography induced by the infinite plane was given by Hartley and Rother et al., but they needed 4 points on a reference plane be visible in all views.

因为空间中不在同一直线上的3个点恰好确定一个平面，所以它避免了Hartley和Rother等方法中需要确定空间4个点是否共面这一比较棘手的问题。

A new algorithm is presented to determine infinite homography matrix and camera intrinsic matrix parameters under one camera motion set from the matched-point sets on two orthogonal planes.

摘要论述由位于正交平面上的特征点对集合复原无穷远单应性矩阵和摄像机内参数的新算法。

In this thesis, we implement a real-time pointing system which, unlike ordinary 3D reconstruction approaches, uses homography and some known 3D reference planes to reconstruct the target point without using camera's intrinsic parameters and orientation. The basic concept is quite intuitive and easy to realize.

本论文中实作了一个即时的指向系统，不同於其他相关的研究中使用传统三维重建的方法来找出指向点，我们没有使用到相机的内部参数以及朝向等资讯，而是利用平面投影转换以及一些三维空间内的平面关系作为系统实作的基础，概念上较为直觉而且也相对地容易理解。

Keywords: feature point matching,homography,affine transformation,location error compensation,epipolar geometry

为了提高图像匹配的精度，提出了一种针对两幅图像的高精度特征点自动匹配算法。

In addition, we prove that for a given set of camera motions such as {(R,t1),(R,t2)},if (t1 ,t2) are not linearly dependent, then the homography of the plane at infinity under this motion set can be linearly and uniquely determined.

另外同时给出了由极点确定关于无穷远平面单应性矩阵的充分必要条件。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
