我们描述了一个本质上与算法无关的投影重建与欧几里得重建的实验比较。对于纯射影结构，即使存在较大的校准误差，欧几里得方法也与射影方法一样精确。投影优化比它的欧几里得等效优化具有更少的局部极小问题。我们描述了增强优化算法收敛性的技术。
We describe an essentially algorithm-independent experimental comparison of projective versus Euclidean reconstruction. The Euclidean approach is as accurate as the projective one, even with significant calibration error and for the pure projective structure. Projective optimization has less of a local-minima problem than its Euclidean equivalent. We describe techniques that enhance the convergence of optimization algorithms.
