If this works in humans, old age could be a much happier time of life. Ummm.... huh? Two problems I have with that sentence:
1.) Granted, I'm 34, so I'm not talking from experience, but from what I gather old age is already a happier time of life.
2.) If I'm interpreting the sentence correctly, the sentence is implying that most of the time when people reach old age they get Alzheimer's. If that is true, then I need a reality check because I didn't know that.
Yes - it must take foreshortening into account. Briefly what it does is calibrate the camera's parameters (field-of-view for one) from the reference DigiTarget image which has known dimensions, and generates a perspective transformation from that. This should be a simple exercise in computer vision.
Notice how it only measures horizontal and vertical lengths. This is because these have particularly special invariance properties under a perspective transformation.
This leads me to deduce that the DigiTarget must always be shot head-on for this thing to work at all.
Les Stroud talked about this on an episode of Survivorman; what you're supposed to do to avoid rabbit starvation is eat the entire rabbit, from top to bottom, bones, eyes, brains, etc (but not the fur).

And which fundamental law of the universe is the one that dictates good use of a rigid pole requires more than one entity?
A comment posted to that blog addresses that:
