AUTOMATED DETECTION OF SPECULAR REFLECTING ROAD SURFACES USING POLARIMETRIC IMAGE DATA - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240300518 titled 'AUTOMATED DETECTION OF SPECULAR REFLECTING ROAD SURFACES USING POLARIMETRIC IMAGE DATA
The patent application describes a detection system for a host vehicle that utilizes a camera, GPS receiver, compass, and electronic control unit (ECU) to detect specular reflecting areas on the road surface.
- Camera collects polarimetric image data of the road surface illuminated by the sun.
- GPS receiver provides the present location of the vehicle as a date-and-time-stamped coordinate set.
- Compass gives the directional heading of the vehicle.
- ECU determines the sun's location relative to the vehicle and camera using input data.
- ECU detects specular reflecting areas on the road surface using polarimetric image data and sun's location.
- ECU executes a control action aboard the host vehicle in response to the detected specular reflecting areas.
Potential Applications: - Autonomous driving systems - Road safety applications - Traffic management systems
Problems Solved: - Detection of specular reflecting areas on the road surface - Enhancing vehicle control and safety measures
Benefits: - Improved road surface detection - Enhanced vehicle control in varying lighting conditions - Increased safety for drivers and pedestrians
Commercial Applications: Title: Advanced Road Surface Detection System for Autonomous Vehicles This technology can be used in autonomous vehicles, road maintenance vehicles, and traffic monitoring systems to improve road safety and efficiency.
Questions about the technology: 1. How does the system differentiate between specular reflecting areas and regular road surfaces? 2. What are the potential limitations of this detection system in adverse weather conditions?
Original Abstract Submitted
a detection system for a host vehicle includes a camera, global positioning system (“gps”) receiver, compass, and electronic control unit (“ecu”). the camera collects polarimetric image data forming an imaged drive scene inclusive of a road surface illuminated by the sun. the gps receiver outputs a present location of the vehicle as a date-and-time-stamped coordinate set. the compass provides a directional heading of the vehicle. the ecu determines the sun's location relative to the vehicle and camera using an input data set, including the present location and directional heading. the ecu also detects a specular reflecting area or areas on the road surface using the polarimetric image data and sun's location, with the specular reflecting area(s) forming an output data set. the ecu then executes a control action aboard the host vehicle in response to the output data set.
