How do I combine transforms in the ceres solver?

I have two parameters transformations as input to my Ceres cost function. They are both transforms that are to be combined, in order to reproject my points. Both transforms are given in the form of a Rodrigues rotation vector, and a translation…

How to correctly model a specific optimization problem in Ceres Solver to avoid assert errors?

I'm trying to solve the following optimization problem with Ceres Solver: minimize Φ Where Φ = ||T/tmax||∞ Subject to: TᵀB T <= 0 ||G(J)ᵀT+w||² = 0 -Tmax <= T <= Tmax with cost function gradient: ∇Φ = tᵢ / tmax; if tᵢ = tmax or 0…
