Improvement of Camera Calibration Board for Unmanned Aerial Vehicle
LU Yating
Abstract：In order to apply the camera application technology to unmanned aerial vehicle and control the unmanned aerial ve?hicle to land on the specific place to charge itself,an improved camera calibration board is designed to solve the problems that there are no reference to know the direction in the air,the camera calibration board cannot be fully-automatic identified and it may lack some part in the calibration board. The new camera calibration board replaces the traditional symmetrical camera calibration board of black and white squares with unsymmetrical camera calibration board of dots. The new calibration board is used to optimize the process of calculating coordinates. The image is scanned for object detection,the dots in the image are identified and the coordinate of the centre of the dots is calculated. Then the coefficient distance between the camera calibration board and unmanned aerial vehi?cle is gotten.
