Detecting Moving Objects using a Single Camera on a Mobile Robot in an Outdoor Environment
نویسندگان
چکیده
Robust detection of moving objects from a mobile robot is required for safe outdoor navigation, but is not easily achievable since there are two motions involved: the motions of moving objects and the motion of the sensors used to detect the objects. We have experimented with a probabilistic approach for moving object detection from a mobile robot using a single camera in outdoor environments. The ego-motion of the camera is compensated using corresponding feature sets and outlier detection, and the positions of moving objects are estimated using an adaptive particle filter and EM algorithm. The algorithms are implemented and tested on three different robot platforms (robotic helicopter, Segway RMP, and Pioneer2 AT) in an outdoor environment, and the detection results are analyzed.

Motion detection by a moving observer using Kalman filter and neural network in soccer robot
In many autonomous mobile applications, robots must be capable of analyzing motion of moving objects in their environment. Duringmovement of robot the quality of images is affected by quakes of camera which cause high errors in image processing outputs. In thispaper, we propose a novel method to effectively overcome this problem using Neural Networks and Kalman Filtering theory. Thistechnique u...

متن کاملIndoor Positioning System Based on Distributed Camera Sensor Networks for Mobile Robot
An importance of accurate position estimation in the field of mobile robot navigation cannot be overemphasized. In case of an outdoor environment, a global positioning system (GPS) is widely used to measure the position of moving objects. However, the satellite based GPS does not work indoors. In this paper, we propose a novel indoor positioning system (IPS) that uses calibrated camera sensors ...
متن کاملMoving Object Tracking using Single Camera on Aerial Robot
Robust detection of moving objects from an aerial robot is required for safe outdoor navigation, but is not easily achieved because the motion is two fold: motion of the moving object and motion of the robot itself. Our goal is to have the robot identify the actual moving objects from the dynamic camera view space, track the moving objects and give the right command to avoid any potential impac...

This paper presents a system to track moving humans in an indoor environment. We propose a cooperative approach of monocular camera and omnidirectional camera to the problem of finding humans by a mobile robot. A cooperation of fixed and moving platforms is proposed for this approach, which features background subtraction, pixel classification, color blob merging, color blob relation and segmen...
