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: |
