perspectiveTransform() fails
I'm trying to retrieve the position of my matched object, I'm using this tutorial https://docs.opencv.org/3.4.1/d7/dff/...
So far my code is https://gist.github.com/Menuka5/de971...
Instead FlannBasedMatcher which is given in the tutorial I use BFMatcher with NORM_L2.
Problem is when I go to perspectiveTransform it gives an error like below.
I have no idea what makes the cv::Exception? Please help
would you be so nice, and swap the screenshot with a text version of the error ?
will do. Tomorrow, currently away from the pc
