System and method for determining characteristic information of an object positioned adjacent to a route
First Claim
1. A system for determining one of an active status and a color of a light signal positioned adjacent to a route, said system comprising:
- a thermal camera configured to collect infrared spectral data of said light signal, said first camera being attached to an exterior surface of a powered system traveling along said route;
a video camera configured to collect visible spectral data of said light signal, said video camera being attached to the exterior surface of the powered system; and
a controller coupled to said thermal camera and said video camera, said controller being configured to determine said one of the active status and color of the light signal based on said infrared spectral data and said visible spectral data of said light signal;
wherein said controller includes a memory to store a minimum active temperature required to activate the light signal, and wherein said controller is configured to determine said active status of said light signal, based upon;
said infrared spectral data including a light signal temperature greater than the minimum active temperature, andsaid visible spectral data having an overlap ratio with said infrared spectral data which exceeds a predetermined overlap ratio stored in the memory.

Abstract
A system is provided for determining characteristic information of an object positioned adjacent to a route. The system includes a first camera configured to collect a first set of spectral data of the object. The system further includes a second camera configured to collect a second set of spectral data of the object. The first and second cameras are attached to a powered system traveling along the route. The system further includes a controller coupled to the first camera and the second camera. The controller is configured to determine the characteristic information of the object based on the first set of spectral data and the second set of spectral data of the object. Additionally, a method is provided for determining characteristic information of the object positioned adjust to the route.

12. A method for determining one of an active status and a color of a light signal positioned adjacent to a route, said method comprising:
-
collecting a infrared set of spectral data of said light signal; collecting a visible set of spectral data of said light signal; and determining said one of the active status and the color of said light signal based on said infrared set of spectral data and said visible set of spectral data of said light signal; storing a minimum active temperature required to activate the light signal; determining said active status of said light signal, based on the steps of; determining if a light signal temperature of said infrared set of spectral data exceeds the minimum active temperature, and determining if an overlap ratio of said visible data of said light signal with said infrared spectral data of said light signal exceeds a predetermined overlap ratio stored in the memory. - View Dependent Claims (13)
