Tracking of Ball Trajectories with a Free Moving Camera-Inertial Sensor

چکیده
This paper is motivated by the goal of a visual perception system for the RoboCup 2050 challenge to win against the human worldcup champion. Its contribution is to answer two questions on the subproblem of predicting the motion of a flying ball. First, if we could detect the ball in images, is that enough information to predict its motion precise enough? And second, how much do we lose by using the real-time capable Unscented Kalman Filter (UKF) instead of non-linear maximum likelihood as a gold standard? We present experiments with a camera and an inertial sensor on a helmet worn by a human soccer player. These confirm that the precision is roughly enough and using an UKF is feasible.

Developing optimal flocking control procedure is an essential problem in mobile sensor networks (MSNs). Furthermore, finding the parameters such that the sensors can reach to the target in an appropriate time is an important issue. This paper offers an optimization approach based on metaheuristic methods for flocking control in MSNs to follow a target. We develop a non-differentiable optimizati...
متن کاملImproving Stability of Vision-based Camera Tracking by Smartphone Sensors
3D tracking is a trending issue in the field of augmented reality, which brings several challenges in a variety of situations, such as estimating the camera poses in dim conditions, obstructed scenes. It is difficult to stabilize the pose estimation results, especially when the result is dependent on only camera images under occlusions. However by using inertial sensors in smartphones, we can o...

Accurate acquisition of camera position and orientation is crucial for realistic augmentations of camera images. Computer vision based tracking algorithms, using the camera itself as sensor, are known to be very accurate but also time-consuming. The integration of inertial sensor data provides a camera pose update at 100 Hz and therefore stability and robustness against rapid motion and occlusi...
متن کاملMoving Vehicle Tracking Using Disjoint View Multicameras
Multicamera vehicle tracking is a necessary part of any video-based intelligent transportation system for extracting different traffic parameters such as link travel times and origin/destination counts. In many applications, it is needed to locate traffic cameras disjoint from each other to cover a wide area. This paper presents a method for tracking moving vehicles in such camera networks. The...
متن کاملOff-the-shelf vision for a robotic ball catcher
In this paper we present a system for catching a flying ball with a robot arm using off-the-shelf components (PC based system) for visual tracking. The ball is observed by a large baseline stereo camera, comparing each image to a slowly adapting reference image. We track and predict the target position using an Extended Kalman Filter (EKF), also taking into account the air drag. The calibration...
