TRAFFIC LIGHT DETECTING SYSTEM AND METHOD
First Claim
1. A method of identifying a traffic light status, where the status comprises at least one of a color illumination status and a sign status of a traffic light, the method comprising:
- receiving, at a user device, geolocation data associated with the traffic light and the user device, the user device geolocation data including a location of the user device, and the traffic light geolocation data including a location of the traffic light;
detecting an elevation and a direction of the user device;
generating, with the user device, one or more instructions to orient the user device to face the traffic light based on the geolocation data associated with the traffic light and the user device, and on the elevation, the direction and an orientation of the user device;
capturing one or more images of the traffic light by an image capture device of the user device;
performing with the user device image processing on the captured images to determine a status of the traffic light; and
communicating the status to a user of the user device.

Abstract
Systems and methods are provided for determining the status of traffic lights through a mobile device and communicating the status to the user of the device. The mobile device detects its geographical location, direction and elevation. The mobile device also receives information related to traffic lights, such as location and type. The device calculates positional deviation from the device to the traffic light and generates one or more prompts in the form of audible or tactile cues that progressively guide the user to point the device at the traffic light. The mobile device detects the image and color of the traffic light and determines the illumination and sign status of the traffic light. Then the mobile device communicates the traffic light status to the user.

11. A device for identifying a traffic light status of a traffic light, the device comprising:
-
memory for storing geolocation data of the traffic light, geolocation data of the device, and direction information and elevation information for the device; and a processor coupled to the memory, the processor being configured to execute a set of instructions stored in the memory to; receive the geolocation data of the traffic light and the device; determine a current elevation and a current direction of the device; determine with the device one or more instructions to orient the device to face the traffic light based on the received geolocation data, the current elevation, the current direction and an orientation of the device; receive light signals from a plurality of light sources, where one of the light sources comprises the traffic light; filter light signals for frequency ranges emitted by the traffic light, the status including at least one of a color illumination status and a sign status; and communicate the status to a user of the device. - View Dependent Claims (12, 14, 16, 17, 18, 19, 20)
