This a camera calibration toolbox for generic lenses. The toolbox can be used to calibrate conventional, wide-angle and fish-eye lens cameras. The calibration is based on viewing a planar calibration object. The intrinsic and extrinsic camera parameters are estimated from control point correspondences between the calibration plane and calibration images. This toolbox is a result of research that has been carried out in the Laboratory of Computational Engineering at Helsinki University of Technology and in the Machine Vision Group at University of Oulu.

人脸对齐基于论文《fps3000》中训练集构建时生产68个特征点的matlab脚本文件。提供交互窗口，按顺序点左眼右眼和嘴巴，即可自动生成68个点，再用鼠标对个别点进行人工修正。满意后保存即生成一个文本文件，存有68个点的坐标。(Face aligned on the paper fps3000 production when the training set to build 68 feature points matlab script file. Provide interactive window, press the right and the left dot sequence mouth, you can automatically generate 68 points, then the mouse on the individual points manually corrected. The satisfaction of saving a text file that is generated, there are the coordinates of 68 points.)
