In view of the shortcoming that the traditional video monitoring device is inconvenient to move, in this paper, we take the tracked intelligent vehicle as the research object and design a mobile video monitoring system based on Android. The system collects the video information of the environment around the intelligent vehicle through the camera and then transmits the video information to the Android...
In this paper, based on quaternion and Euler angles, an attitude control algorithm is proposed for pitching and rolling of quadrotor aircraft. In addition, the target tracking algorithm of quadrotor aircraft is designed by using the collected video information and color feature recognition. The system is based on the homemade quadrotor aircraft, using gyroscope, accelerometer as the original measurement...
Aiming at the task of autonomous search and target capture for the intelligent vehicle, in this paper, the intelligent vehicle with a four-degree-of-freedom manipulator was taken as the research object. Firstly, the D-H (Denavit-Hartenberg Matrix) method is utilized to construct a model of the manipulator by MATLAB, and a method is given to calculate the analytical solution of the angle of manipulator...
With the rapid improvement of three-dimensional scanner hardware technology, the accuracy of the point cloud is getting higher and higher, so the number of point-clouds is increasing shar ply, which greatly affects the speed and performance of point-cloud registration. Based on feature matching and ICP algorithm, a 3D point-cloud model stitching algorithm by using Kinect sensors scanning was proposed...
This paper proposes a novel infrared camera array guidance system with capability to track and provide real time position and speed of an air robot during a landing process. The system mainly include three novel parts: (1) Infrared camera array and infrared laser lamp based cooperative long range optical imaging module; (2) Large scale outdoor camera array calibration module; and (3) Laser marker...
The infrared camera array devices, which are important components of the air robot automatic optical navigation system, need to be calibrated for keeping the effectiveness and precision of tracking and location. We propose a brand new method for automatic calibration of infrared camera array, we focus on the rotation matrices and translation matrices between the cameras and the world coordinate. We...
Vision measurement technology research is active in recent years, which has broad application prospect in the fields of military and civilian industrial production. On the basis of comparing several existing measurement techniques, our paper mainly studied a method of geodetic coordinate calculation based on monocular vision on UAV platform, which is extension and expansion of the traditional monocular...
Visual interpretation of natural pointing gestures is essential in a human robot interaction scenario. Both hands and head are involved in pointing behaviors. Given the color images acquired by a web camera and the depth data by a TOF range camera, we perform visual tracking of the head and hands in 3D space. We investigate both the Head-Finger Line (HFL) and the forearm orientation as the estimation...
Recognition of non-verbal gestures is essential for robots to understand a user's state and intention in a Human-Robot Interaction (HRI) scenario. In this paper a multi-modal system is proposed to recognize a user's hand gestures and estimate body poses from the robot's viewpoint only. A range camera is employed to derive the depth data at a high frame rate. Depth data is useful for image segmentation,...
