A method and system provide road and obstacle detection in navigating an autonomous vehicle. The method comprises scanning a distance ahead of the autonomous vehicle to obtain a current range scan, and obtaining navigation data, including dynamics, position, and orientation measurements of the autonomous vehicle. The current range scan is transformed to world coordinates with respect to a reference location based on the navigation data, and the transformed current range scan is input into a distance-based accumulator. The transformed current range scan is added to a variable size buffer when the autonomous vehicle is deemed to be non-stationary. A ground plane is estimated from the transformed current range scan and prior range scans stored in the variable size buffer. The estimated ground plane is represented as a constrained quadratic surface, which is classified into one or more of a traversable area, a non-traversable area, or an obstacle area for navigation of the autonomous vehicle.

Laser ranging process for road and obstacle detection in navigating an autonomous vehicle

A system and method for providing information for autonomous vehicle navigation are disclosed. The system comprises at least one laser scanner configured to perform one or more range and intensity scans of an area around the autonomous vehicle, and a geo-location unit comprising one or more global positioning system sensors and inertial navigation system sensors. The system also includes at least one processor in operative communication with the laser scanner and the geo-location unit. The processor is configured to execute one or more program modules comprising a ground plane-based processing module configured to receive range scan data transformed into world coordinates, and output ground plane-based classification data; a range-based processing module configured to receive data from a single range scan, and output range-based classification data; an intensity-based processing module configured to receive intensity scan data, and output intensity-based classification data; and a classification fusion module configured to receive the classification data from each of the processing modules, and output range bin classification data.

System and method for navigating an autonomous vehicle using laser detection and ranging

A computer/computer network security alert management system aggregates information from multiple intrusion detectors. Utilizing reports from multiple intrusion detectors reduces the high false alarm rate experienced by individual detectors while also improving detection of coordinated attacks involving a series of seemingly harmless operations. An internal representation of a protected enclave is utilized, and intrusion detection system (IDS) information is correlated to accurately prioritize alerts. In one embodiment, the system is capable of utilizing data from most existing IDS products, with flexibility to add further IDS products.
