Checkerboard Tracker for Camera Calibration

49 15

Description

Camera calibration is an important first step for computer vision applications. While checkerboard extraction is considered a solved problem, The Camera Calibration Toolbox for Matlab [1] requires one to manually enter the edges of the checkerboard in order for the tool to both: define an origin and guide the checkerboard extraction algorithm. [5] The goal of this project is to automatically determine the extreme corners of the checkerboard and track an arbitrarily selected origin such that the camera calibration process may be automated.

 

The image illustrates the Camera Calibration utility determining the corners of the checkerboard with aid from the corner extraction code developed for this project.
