Embodiment Construction

[0013] The present invention increases the situational awareness of the user of the bio-optical device by detecting events when the telephoto lens is used based on in-vehicle monitoring of the driver state monitoring camera. When the use of the telephoto lens is detected, the gaze of the eye viewed through the one or more telescopic lenses is analyzed to determine the direction of the gaze. The gaze direction points to a region of interest far outside the vehicle. Remote sensors in the vehicle (eg, forward-looking cameras) identify the surrounding scene. Known methods such as pattern recognition and image analysis are used to automatically identify specific objects and / or key driving indicators (eg, traffic signs, such as the color of traffic lights or traffic signs). HMI interfaces (audio and / or visual) provide situational awareness by communicating driving indicators to the driver. To improve the robustness of detection of telescopic lens usage and gaze direction based on ...

Abstract

The present disclosure provides a driver assistance system for a driver using a bio-optical lens. Assistance is provided to a driver of a road vehicle using bio-optical eyewear having a carrier lens and a telephoto lens. It is detected that a driver wears bio-optical glasses while driving a vehicle. A spatial location of a driver wearing bio-optical glasses is tracked to identify a telephoto event that the driver is viewing through a telephoto lens. A gaze direction through a telephoto lens is detected during a telephoto event. Remote sensing data covering the region of interest corresponding to the projection of the gaze direction is collected. An object is detected within the region of interest. A driving indicator is identified from the object. The driving indicators are presented to the driver as supplemental information to highlight key driving indicators, such as indicia and the color of traffic lights.

Description

technical field [0001] The present invention relates generally to a driver assistance system, and more particularly to providing enhanced driver information based on a region of interest examined by the driver through the telephoto portion of a bio-optical vision device. Background technique [0002] Low vision drivers can use bio-optic glasses to assist them while driving. These specialized bio-optic glasses have a normal carrier lens and a telephoto lens mounted on or near the carrier lens above the eye. The driver looks primarily (eg, 95% of the time) through the carrier lens to monitor the wide field of view. To spot distant objects and / or other aspects of the environment, the driver briefly looks through a telephoto lens. Bio-optical glasses may generally include a frame holding left and right bearing lenses. There may be telescopic elements on one or both carriers, and the telescopic portion may be binocular or monocular. [0003] To use the telephoto portion, the ...
