Audio detection of moving vehicles

1997 IEEE International Conference on Systems, Man, and Cybernetics. Computational Cybernetics and Simulation, 2002
The purpose of the paper is to present some simple but effective techniques for detecting vehicles in motion based on the energy radiated from the axles. These techniques can be applied to the implementation of vehicle counters and detectors for traffic management control.

Moving Vehicles Detection in Airborne Video

2008 International Symposium on Information Science and Engineering, 2008
A method to detect moving vehicles in airborne video is proposed in this paper. In order to deal with moving object detection in non-stationary background, the global motion of background is estimated frame by frame according to the correspondence control points extracted by Harris feature point extraction algorithm.

Acoustic Detection of Moving Vehicles

2018
This chapter outlines a robust algorithm to detect the arrival of a vehicle of arbitrary type when other noises are present. It is done via analysis of its acoustic signature against an existing database of recorded and processed acoustic signals. To achieve it with minimum number of false alarms, a construction of a training database of acoustic ...

Detecting and tracking moving humans from a moving vehicle

SPIE Proceedings, 2008
In September 2007 the Army Research Laboratory (ARL) Robotics Collaborative Technology Alliance (CTA) conducted an assessment of multiple pedestrian detection algorithms based upon LADAR or video sensor data. Eight detection algorithms developed by the Robotics CTA member organizations, including ARL, were assessed in an experiment conducted by the ...

Vision-based side vehicle detection from a moving vehicle

2010 International Conference on System Science and Engineering, 2010
In this paper, a side vehicle detection system with real-time on-board vision is proposed. The system employs camera vision to detect side moving vehicles, and provides necessary warning to drivers and passengers when the vehicle is making lane change.

Vision-Based Lane Marking Detection and Moving Vehicle Detection

2016 8th International Conference on Intelligent Human-Machine Systems and Cybernetics (IHMSC), 2016
Due to the fast augment of vehicles, traffic accidents become more and more frequent. People's safety is threatened seriously. Vision-based lane marking detection and moving vehicle detection are of great importance to the driving safety. In this paper, we propose a constraint between Sobel operator and Shen Jun edge operator to detect the lane marking

Moving cast shadow suppression for vehicle detection

SPIE Proceedings, 2005
Vehicle detection is critical to traffic surveillance and management systems. In real outdoor daylight scenes, shadows cast by moving vehicles are often detected as a part of the moving vehicles since shadows move in accordance with the movement of vehicles, which will heavily affects accuracy of vehicle detection.

Moving Vehicle Detection for Automatic Traffic Monitoring

IEEE Transactions on Vehicular Technology, 2007
A video-based traffic monitoring system must be capable of working in various weather and illumination conditions. In this paper, we will propose an example-based algorithm for moving vehicle detection. Different from previous works, this algorithm learns from examples and does not rely on any a priori model for vehicles.

Detection of text marks on moving vehicles

Seventh International Conference on Document Analysis and Recognition, 2003. Proceedings., 2004
Vehicle text marks are unique features which are useful for identifying vehicles in video surveillance applications. We propose a method for finding such text marks. An existing text detection algorithm is modified such that detection is increased and made more robust to outdoor conditions.

Obstacle Detection from a Moving Vehicle

1995
In this paper a method to compute a reliable optical flow from image sequences and detect static and moving obstacles during ego-motion is presented. The method consists of two phases: an off-line calibration phase during which a reference optical flow relative to the ground plane and a given camera velocity is computed; a fast on-line procedure to ...
