2016-02-18 00:46:43 -0600 | asked a question | OpenCV 3.1 UMat assignment I am trying to implement a performance upgrade to the project of my company. The project depends on OpenCV and recently I have successfully upgraded to OpenCV 3.1 to use UMat. Though I cant find a complete tutorial on it except basic operations. So I am stuck at the following: This doesnt work Neither does this: These cause an exception. And this one results with a two dimensional mat with 0 rows and 0 cols... Also another case is: Need help. Thanks in advance!!!! |
2013-01-20 03:55:13 -0600 | asked a question | OpenCV Stereo Matching Essential Matrix weird values I have a stereo setup using OpenCV and two webcams (The one in the book Lerning OpenCV by H&Z). I computed essential and fundamental matrices, intrinces extrinces etc using BM correspondancy algorithm. Now I want to find the matching point of a pixel in left image in the other image. To do this I have defined the following function, which is incomplete since my primary aim is to calculate real world distance. } Also Id like to know if im on the right path to find the 3D distance of the pixel in real world coordinates? |
