First, let me say that this is a very neat project for a high schooler before what I say next because I'm not trying to downplay what he did. He figured out how to overlay an image in realtime over video, which is neat.

However, this is only a small part of what is actually done to present the final image. The more complicated part is the computer vision which allows for things like composing the image so that the swimmers are always above the labels (i.e. the superimposed labels appear to be at the bottom of the pool). They also are using computer vision to recognize where the labels should go, rather than some kind of positional mount on the camera as he suggests. The image is processed through a computer which is capable of recognizing the lane lines, the boundaries of the pool, and the bottom of the pool. This way, when the camera moves the image is updated automatically.

Again, I'm not trying to downplay what was done here, it is a very nice hack.

It appears that they got caught plagiarizing another newspaper: http://www.thetimes.co.uk/tto/life/article3606527.ece
