Web8 de jan. de 2013 · In this tutorial is explained how to build a real time application to estimate the camera pose in order to track a textured object with six degrees of freedom given a 2D image and its 3D textured model. The application will have the following parts: Read 3D textured object model and object mesh. Take input from Camera or Video. Web7 de fev. de 2014 · Hi I'm a newby starting to understand openCV and it's use to create and display graphics on the screen of my laptop. I'd like to use opencv to draw a chess-board (not the checker pattern often used to calibrate, that's not a chess board) and to display that. Then I'd like to create small images for each of the chess pieces and then then place …
