A method for identifying route-related hazards using image data obtained from a camera unit on an aerial device. | 06-11-2015 |
20150235094 | VEHICLE IMAGING SYSTEM AND METHOD - An imaging system and method generate image data within a field of view that includes a cab of the vehicle and a portion of a route being traveled on and/or wayside devices disposed along the route. The cab includes a space where an operator of the vehicle is located. The image data generated by the camera is examined to identify route damage, a deteriorating condition of the route, and/or a condition of the wayside devices. The condition of the wayside devices can include damage to the wayside devices, a missing wayside device, deterioration of the wayside devices, or a change in terrain. | 08-20-2015 |
20150269722 | OPTICAL ROUTE EXAMINATION SYSTEM AND METHOD - Optical route examination systems and methods described herein obtain image data of a field of view of a camera disposed onboard a first vehicle as the first vehicle moves along a first route, and autonomously examine the image data onboard the first vehicle to identify one or more of a feature of interest or a designated object. | 09-24-2015 |
20160039436 | AERIAL CAMERA SYSTEM AND METHOD FOR DETERMINING SIZE PARAMETERS OF VEHICLE SYSTEMS - An aerial system and method use a distance sensor to measure spatial distances between the distance sensor and plural vehicles in a vehicle system formed from the vehicles operably coupled with each other during relative movement between the distance sensor and the vehicle system. The spatial distances measured by the distance sensor are used to determine a size parameter of the vehicle system based on the spatial distances that are measured. | 02-11-2016 |
