Efficient Global Optimization of Non-differentiable, Symmetric Objectives for Multi Camera Placement [article]

Maria L. Hänel, Carola-B. Schönlieb
2021 arXiv   pre-print
This allows to flexibly handle difficult objective functions that are often expensive and quantized or non-differentiable. The solver is globally convergent and easily parallelizable.  ...  We propose a novel iterative method for optimally placing and orienting multiple cameras in a 3D scene.  ...  We will demonstrate the originality of our method and a general demand for an efficient solver for optimal camera placement in Section II. Section III elaborates on the design of the solver.  ...
