Ceres-Solver学习记录(零)：初识

为什么起名为Ceres呢？

• 简而言之，纪念Gauss利用最小二乘方法来预测Ceres谷神星的轨迹
• http://ceres-solver.org/index.html#id1

Ceres-Solver可以用来解什么问题：

• Non-linear Least Squares problems with bounds constraints, 带边界约束的非线性最小二乘问题
• general unconstrained optimization problems, 一般的无约束优化问题
• http://ceres-solver.org/tutorial.html

Ceres-Solver可以用于哪些领域：

• fitting complicated curves in statistics （在统计学中，用于拟合复杂的曲线）
• constructing 3D models from photographs in computer vision（在CV领域：基于图像重建三维模型）

Ceres-Solver用于哪些项目：

• http://ceres-solver.org/users.html
• 广泛用于多视图几何、SLAM和三维重建等领域
• One of the main reasons for writing Ceres was our need to solve large scale bundle adjustment problems
