Sure you can, but you need to get a baseline to start from, which can be found by going through the trig for one image, or going to a field and finding it through measurements there.

Yeah, this is what I hope to do, since the error is much less than using a single target. But, if one target is not found, you will need to do the math without it, which makes things very interesting (and a whole lot of if-else, unless I find a more elegant way to do it)
