Copterix: Lucas and Kanade

Today, we began to write some articles for the website and we mainly worked on Lucas and Kanade algorithm. We did some tests and we have some good results when the camera is recording pictures from the ceiling, but we have bad results when they are from the floor. Here is some illustrations:These pictures represent the evolution of the helicopter movement (x and y). The first picture was taken when the camera was watching the floor held by Loïc. We cannot distinguish a good evolution of the motion.

For the second picture, the camera was oriented to the ceiling. The copter was put on a table that we could move. The first peak represents a slow movement in one direction and a fast movement in the opposite direction. The second peak represents the same experiment with the introduction of some manual oscillations.

Tomorrow, in order to solve these problems, we will first of all apply a low pass filter and we will try to use a draughtboard on the floor with a good lighting.
