基于IGBT的T型三电平逆变器在不同工况下的损耗计算，改变输入参数，即可获得相应结果。(matlab mfile，used to the power loss calculation of T-type three level IGBT inverter bridge under different situation)

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.
