Somewhere Over the Rainbow – Colour Detection

One of this years challenges is to detect  some coloured balls from a distance and visit them.

The full details are here.

For our robot we are using a Raspberry Pi Camera and OpenCV to detect the colours and some code written in C++.

You can see a video of our robot doing some colour detection below.

Whilst testing this we have come unstuck with the detection when it is dark or when somebody (Vince) in a very red coat walks into the frame of the camera and it detects him and not the ball.

We are planning on using a 2 times lens to bring the balls into a better focus.
