fiducials: checkerboard_detection
Package Summary
The checkerboard_detection package can be used to determinate the position and the orientation of a checkerboard of the known size within an image with calibration information (checkerboard_pose node). The position of the board/camera will be published as tf frame. Stored data can be published again with using by using static_pose node with constant frequency or synchronized with published frames using the checkerboard_pose node.

Overview
The checkerboard_detection package can be used to determinate the position and the orientation of a checkerboard of the known size within an image and calibration information (checkerboard_pose node). The position of the board/camera will be published as tf frame. In the background the node uses the OpenCV functions cv::findChessboardCorners, cvFindCornerSubPix and cv::solvePnP. The pose can be optional stored in a yml file. Stored data can be published again with using by using static_pose node with constant frequency or synchronized with published frames using the checkerboard_pose node.
