Vision-Based Target Detection and Tracking System for a Quadcopter

چکیده
Tracking a maneuvering target with quadcopter is challenging problem, that involves variety of fields such as visual tracking, state estimation, and control algorithms. Most existing unmanned aerial vehicle (UAV) systems fail to track targets accurately in the long term cannot relocate after loss. This paper aims design implement vision-based tracking system for quadcopters can steadily ground well air without any prior information. We employ vision detection algorithm select quickly precisely. To fit complex practical conditions, developed based on correlation filters, which capable large-scale variation fast motion. In addition, an efficient redetection support vector machine (SVM) designed handle occlusions The states are estimated from information by improved Lucas-Kanade (LK) optical flow method extended Kalman filter (EKF). Moreover, double closed-loop Proportion Integral Differential (PID) controller using follow target. By implementing main algorithms onboard NUC computer, extensive outdoor flight evaluated platform equipped stereo camera. experimental results validate feasibility practicability system.

متن کاملA Robust Vision-based Moving Target Detection and Tracking System
In this paper we present a new algorithm for real-time detection and tracking of moving targets in terrestrial scenes using a mobile camera. Our algorithm consists of two modes: detection and tracking. In the detection mode, background motion is estimated and compensated using an affine transformation. The resultant motionrectified image is used for detection of the target location using split ...

Unmanned Aerial Vehicle (UAV) has been deployed in a variety of applications like remote traffic surveillance, dangerous area observation, and mine removal, since it is able to overcome the limitations of ground vehicles. It can also be used for traffic controlling, border patrolling, accident and natural disaster monitoring for search and rescue purpose. There are two important tasks in the UA...
متن کاملNovel target segmentation and tracking based on fuzzy membership distribution for vision-based target tracking system
One of the basic processes of a vision-based target tracking system is the detection process that separates an object from the background in a given image. A novel target detection technique for suppression of the background clutter is presented that uses a predicted point that is estimated from a tracking filter. For every pixel, the three-dimensional feature that is composed of the x-position...
