Augmented Reality

Recently I had a computer vision assignment that was loads of fun. The assignment was on calibrating a camera based on images of a calibration grid (checkered board shown below) from different angles.



Once the calibration was done using linear algebra we were able to project clipart images onto the calibration grid. This is the same as the projected advertisements you see on football fields on TV.



Then we augmented images with 3D structures. The first was a 3D cube which looks like its sitting on the calibration grid. Its a bit hard to see the outline of the cube in the image below, so you may want to click on it to view it enlarged. The second is a 3D mesh object which is projected onto the grid.
