ita_{t}: mean effective solving time (average time to obtain one correct solution)
To demonstrate our method on a hard problem, we develop an efficient solver for the “Scranton” minimal problem obtained by relaxing the overconstrained problem of four points in three views (4pt) [50].
We train a model that predicts a starting problem for a single path real HC method to find a good solution.
Our solver is implemented efficiently in C++ and evaluated on the state-of-the-art data in computer vision.
It successfully solves about 26.3% of inputs in 16.3µs, Tab. 4.
In Sec. 9 we show that when used in RANSAC, about 4 samples suffice on average to obtain a valid candidate of camera geometry in 61.6µs.
No such efficient solver has been known for this problem before.
The best-known runtime for a very carefully designed approximation of the problem, reported in [50], was on the order of milliseconds.
We thus achieve more than ten times speedup compared to [50]. -> 10~100倍の高速化
カメラ姿勢推定のような、多くの偽の解をもつ連立方程式を解く必要があるタスクがμsオーダーで解けるようになった。
