Description: 已知图象4点坐标和转换后图像相对应4点坐标， 利用openCV求出homograghy 3x3 矩阵， 然后输出变换后图像-There is an input image called "warpin". The goal is to warp this image so that the tiles are approximately square, that is the camera is rotated to look down, which produces an image called warpout, also on the web site. I have measured the corners of the four points necessary to do the warp. They are:
From x,y To x,y
Top Left 75,169 => 103, 19
Top Right 118,165 => 192, 19
Bottom Left 62,222 => 105, 205
Bottom Right 148,216 => 192, 205
The origin of the image is in the top left corner. This is an OpenCV program that takes the warpin image, and using these given transformation coordinates produces the warpout image. Platform: |

Description: 主要阐述了一种适用于户外AR系统(augmented reality system)的注册方法；利用标记物计算初
始结构参数，并确定初始的共面自然特征点集；在后续的运行过程中, 通过相关系数法在相邻的两帧画面
中寻找候选匹配自然特征点对；采用了基于标记物提供的共面约束和 RANSAC（RANdom Sample
Consensus）算法相结合的方法，从这些候选匹配点中选出满足共面条件的匹配点对；计算这些共面点所对
应的单应矩阵(Homography)，进而求解相机的运动参数，完成虚拟物体的注册。该方法特别适合没有显式
平面结构的室外环境。 -In this paper, a kind of registration method applicable to outdoor AR system (augmented reality system)
is elaborated. The plane marker is employed in calculating initial structure parameter natural features are
tracked from the two adjacent frame through correlation and taken as candidate matches. A method Based on the
constraint of marker and RANSAC (Random Sample Consensus) is adopted, so that good matches, which satisfy
coplanar condition, are selected out of the candidate matches. Through the homographic matrix provided from
the coplanar points, we could work out motion parameter of the camera, and finally finish registration of virtual
objects. The registration method is most appropriate for outdoor surroundings with obscure plane structure. Platform: |
