Vision-Based Horizon Detection and Target Tracking for UAVs
نویسندگان
چکیده
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 UAV system, automatic stabilization and target tracking. Automatic stabilization makes a UAV fully autonomous, while target tracking alleviates the overhead of a manual system. In order to address these, we present computer vision based horizon detection and target tracking for the videos captured by UAV camera. The proposed horizon detection algorithm is an enhancement of the Cornall’s Theorem and our target tracking employs optical flow. The results of both real and simulated videos show that the proposed algorithms are promising.

We study the problem of optimally coordinating multiple fixed-wing UAVs to perform vision-based target tracking, which entails that the UAVs are tasked with gathering the best joint vision-based measurements of an unpredictable ground target. We utilize an analytic expression for the error covariance associated with the fused measurements of the target’s position, and we employ stochastic fourt...

متن کاملFixed-Wing Attitude Estimation Using Computer Vision Based Horizon Detection
The last decade has seen a dramatic expansion in the deployment of Unmanned Airborne Vehicles (UAVs) as witnessed by deployments to Bosnia, Afghanistan and Iraq. Many low-cost UAVs operate without redundant attitude sensors and are therefore highly vulnerable to the failure of such sensors. It is common for low-cost UAVs to carry a vision sensor as its primary payload. Given that a human pilot ...
