The vision tracking system in this paper estimates the robot position relative to a target and rotates the camera towards the target. To estimate the robot position of mobile robot, the system combines information from an accelerometer, a gyroscope, two encoders, and a vision sensor. The encoders can provide fairly accurate robot position information, but the encoder data are not reliable when robot...
This paper presents a multi-speakers tracking algorithm using audio-visual data fusion. The audio information is the direction of speakers and the visual information is the direction of detected faces. These observations are used as inputs of the tracking algorithm, which employed the framework of particle filter. For multi-target tracking, we present a flexible data association and data fusion, which...
This paper deals with a cooperative object tracking with mobile robotic sensor network. The occlusion problem, which is one of the most important problems of mobile object tracking, will be solve with utilizing the mobile robotic sensor network. Additionally, the high quality information of the object can be observed, since the robotic sensor network can change observation formation their own way...
This paper presents three technical elements that we have developed to improve the accuracy of the visual target tracking for single-sol approach-and-instrument placement in future Mars rover missions. An accurate, straightforward method of rover mast calibration is achieved by using a total station, a camera calibration target, and four prism targets mounted on the rover. The method was applied to...
This paper describes the application of real time vision system for dynamic tracking of moving objects, using image motion. The study encompasses experimental development of an intelligent system that works in ordinary light and is capable of tracking moving objects with unpredictable motion. In this research the task of mobile target tracking using a pan-and-tilt camera is considered with motion-based...
Summary form only given. A scheme has been designed and installed to protect the seaward perimeter of land-based operations. This paper reports on typical threats to these sites from various attack forces and sets out the resultant system that has been installed. This novel solution was proposed because of the many practical problems affecting this type of application. In particular, the site is located...
