Euclidean upgrading from segment lengths: DLT-like algorithm and its variants ?
A DLT-like algorithm for Euclidean upgrading from segment lengths is proposed. The constraint equation is parameterized in a simple way. The plane at infinity is directly extracted from the intermediate results. This algorithm has higher accuracy than the existing linear algorithms. Weighting and nonlinear refinement further improve the accuracy.
