Vigorous 3D Angular Resection Model Using Levenberg – Marquardt Method

The resection in 3D space is a common problem surveying engineering and photogrammetry based on observed distances, angles, coordinates. This nonlinear comprises redundant observations which normally solved using the least-squares method an iterative approach. In this paper, we introduce vigorous angular that converges to global minimum even with very challenging starting values of unknowns. deriving oblique angles from measured horizontal vertical by solving spherical triangles. derived tightly connected rays enclosed between point reference points. Both techniques least square adjustment either Gauss-Newton or Levenberg – Marquardt are applied two experiments. both numerical methods, results converged steadily proposed improper values. However, applying proved reach solution all situations outperformed method.
