Nettet15. jun. 2024 · 1 Answer. Sorted by: 1. Rewrite your equation in matrix form: [ p l − R p r w] [ a b c] = T. If the two rays are not parallel, the matrix on the left is invertible, hence the equation’s solution is simply. [ a b c] = [ p l − R p r w] − 1 T. Ultimately, you want the midpoint of a p l and b R p r. That calculation can be added to the ...

In computer vision, triangulation refers to the process of determining a point in 3D space given its projections onto two, or more, images. In order to solve this problem it is necessary to know the parameters of the camera projection function from 3D to 2D for the cameras involved, in the simplest case represented by the camera matrices.
