In this paper, we explore the concept of a tracker-sensor feedback loop, i.e., how tracker output can inform sensor processing, and investigate whether it can improve multiple target tracking performance and enable stationary object detection in video. Our implementation of the tracker-sensor feedback loop is based on the Gaussian Mixture Models (GMM) foreground detector. We modify the standard GMM...
This paper presents a novel solution for a typical small-scaled quad-rotor UAV to autonomously search for and land on a pre-designed marker placed on a rooftop and to observe a digit panel on the opposite building. The UAV is equipped with a downward-facing monocular camera for landing target detection and pose estimation, as well as a front-facing camera for digit panel observation and surveillance...
Sense and Avoid (SAA) has been identified as one of the crucial technologies for integrating UAV into civil airspace, and vision based SAA is regarded as a promising solution. In this paper we described our vision based SAA system consisted of onboard vision detection system and Groud Control Station (GCS) to fulfill the intruder detection and avoid maneuver control tasks. To realize the small intruder...
