Camera Calibration

Work in progress for camera calibration using adaptative segmentation and ellipse fitting, bassed on:

• Ankur Datta, Jun-Sik Kim, Takeo Kanade, “Accurate Camera Calibration using Iterative Refinement of Control Points”, 2009.
• CD Prakash, LJ Karam,“Camera calibration using adaptive segmentation and ellipse fitting for localizing control points”, Image Processing (ICIP), 2012.
• M. Vo, Z. Wang, L. Luu, and J. Ma, “Advanced geometric camera calibration for machine vision” ,Optical Engineering, Vol. 50, No. 11, 110503, 2011.

Getting Started

To compile and run the code you can write in a terminal:

g++ CameraCalibration.cpp -o CameraCalibration -O3 `pkg-config opencv --cflags --libs` && ./CameraCalibration

Prerequisites

You need to have opencv intalled on your system, it can be achived using the follow command

sudo apt-get install libopencv-dev
