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. Triangulation is sometimes also referred to as reconstruction or intersection. my cat begs to go outside

We present two novel solutions for multi-view 3D human pose estimation based on new learnable triangulation methods that combine 3D information from multiple 2D views. The first (baseline) solution is a basic differentiable algebraic triangulation with an addition of confidence weights estimated from the input images.

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 ...
