In this paper, a visual navigation system is implemented to control a UAV in unknown and GPS-denied environments, using a monocular camera. The navigation system is based on the Semi-direct Visual Odometry algorithm, whose absolute scale is estimated by fusing visual output with altitude measurements. The main contribution of the paper is the recovery mechanisms to reinitialize the visual map when...
In apple harvesting robot stereo vision system, fruit recognition based on least squares support vector machine (LS-SVM) and calibration based on binocular vision are proposed, in order to gain the location information of apples including depth. Firstly, vector median filtering, opening and closing operations are employed, then feature vectors, H and S components in HIS color model and shape features,...
