Converting 2D coordinates from multiple viewpoints into 3D coordinates
- by Kirk Smith
Here's the situation. I've got a set of 2D coordinates that specify a point on an image. These 2D coordinates relate to an event that happened in a 3D space (video game).
I have 5 images with the same event point on it, so I have 5 sets of 2D coordinates for a single 3D coordinate. I've tried everything I can think to translate these 2D coordinates into 3D coordinates, but the math just escapes me. I have a good estimate of the coordinates from which each image was taken, they're not perfect but they're close.
I tried simplifying this and opening up Cinema 4D, a 3D modeling application. I placed 5 cameras at the coordinates where the pictures were taken and lined up the pictures with the event points for each one and tried to find a link, but nothing was forthcoming. I know it's a math question, but like I said, I just can't get it. I took physics in high school 6 years ago, but we didn't deal with a whole lot of this sort of thing.
Any help will be very much appreciated, I've been thinking on it for quite a while and I just can't come up with anything.
