VISIBILITY IMPROVEMENT IN BAD WEATHER USING ENCHANCED REALITY
First Claim
1. A method for improving driver visibility during poor driving conditions, said method comprising:
- determining an orientation and a location of a vehicle;
retrieving data indicative of stationary objects that are anticipated to be detectable at a current orientation and location of said vehicle; and
comparing a captured scene with said data retrieved from said database using said information regarding said orientation and said location of said vehicle such that a matching scene thereof indicates where objects are expected to appear in said captured scene to generate at least one detected object and improve driver visibility with respect to said vehicle during poor driving conditions.

Abstract
Methods and systems for improving driver visibility during bad weather and/or poor lighting for objects such as road signs, road lines, road markings, etc. The disclosed approach can enhance the captured images by exploiting priori knowledge about the scene and the objects that are stored in a database. In general, the orientation and location of a vehicle can be determined, and data can be retrieved which is indicative of stationary objects that are anticipated to be detectable at a current orientation and location of the vehicle. A captured scene is compared to data retrieved from the database using the information regarding the orientation and the location of the vehicle such that a matching scene indicates where objects are expected to appear in the captured scene and improve driver visibility with respect to the vehicle during poor driving conditions.

9. A system for improving driver visibility during poor driving conditions, said system comprising:
-
a processor; a data bus coupled to said processor; and a computer-usable medium embodying computer program code, said computer-usable medium being coupled to said data bus, said computer program code comprising instructions executable by said processor and configured for; determining an orientation and a location of a vehicle; retrieving data indicative of stationary objects that are anticipated to be detectable at a current orientation and location of said vehicle; and comparing a captured scene with said data retrieved from said database using said information regarding said orientation and said location of said vehicle, such that a matching scene thereof indicates where objects are expected to appear in said captured scene to generate at least one detected object and improve driver visibility with respect to said vehicle during poor driving conditions. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)

17. A processor-readable medium storing code representing instructions to cause a process to improve driver visibility during poor driving conditions, said code comprising code to:
-
determine an orientation and a location of a vehicle; retrieve data indicative of stationary objects that are anticipated to be detectable at a current orientation and location of said vehicle; and compare a captured scene with said data retrieved from said database using said information regarding said orientation and said location of said vehicle such that a matching scene thereof indicates where objects are expected to appear in said captured scene to generate at least one detected object and improve driver visibility with respect to said vehicle during poor driving conditions. - View Dependent Claims (18, 19, 20)
