Placing the line-up card

“

- Now that we have some good camera tracking, we're going to lay in a lineup card, which should help us to line up all the other elements in our 3D scene. But before I put in the lineup card, I want to set the ground plane. So I'm going to scrub through here, looking for a frame that has lots of green, and I want to find some points that have low errors, like, let's see, what was this guy? Hmm, his track length is 62, but his error's .854. That's too much, let's find another. Error .866, no thank you. Error 1.0, not good. Let's try another frame, let's scoot over here. Try this guy. Ah, 29-frame track length, error .293, let's select him. Let's look over here. Ooh, an error .227, I'll take that one, too. Shift click on him, I have two, select it. What I want is three or four points well-distributed. So let's look down here. Ooh, error 1.92, error 163. 2.29, 1.82. Ahh, error .225, we'll take that one. And let's see, what's over here? 1.28, 2.05. .804, let's get a better one than that…
