Pose estimation and 3D environment reconstruction are crucial for autonomous navigation in mobile robotics. Robust dense visual odometry based on a RGB-D sensor uses all pixels to estimate frame-to-frame motion by minimizing the photometric and geometric error. 3D coordinates of each pixel are calculated necessarily with its corresponding depth. However, depths of some pixels near object boundaries...
A visual servo control system of intelligent wheelchair mounted robotic arm is presented, which consists of intelligent human-machine interaction (HMI), visual servo controller and motion controller. An adaptive visual feedback controller based 2D image is designed, which ensure that the manipulator reaches a desired position quickly and grasps a target. With the help of human-machine interaction...
This paper presents a monocular vision and odometer based SLAM algorithm, making use of a novel artificial landmark which is called MR (Mobile Robot) code. A brief introduction of MR code system is given. A practical error model for odometric position estimation is described and the parameters are determined through experiments which verify the rationalities of the model. During robot motion, the...
