Foresight Gets Notice of U.S. Patent Allowance for All Weather and Lighting Conditions Vision System

The granted patent is for a multi-spectral system for generating pre-collision alarms that incorporates stereo data fusion and self-calibrating modules.

FREMONT, CA: Foresight Autonomous Holdings Ltd., a pioneer in automotive vision systems, declares that the United States Patent and Trademark Office has granted the Company's patent application, 16/960,452, for a "multi-spectral vehicular system for generating pre-collision notifications."

The patented technique consists of a multi-spectral automotive vision system composed of two stereoscopic infrared and two stereoscopic visible-light sensors. The device has a data fusion module that combines data collected via infrared and visible-light channels to enable accurate obstacle identification and distance estimation. Additionally, integrating the two stereoscopic channels handles edge-case scenarios, particularly in adverse weather and lighting, while minimizing false alarms. The automatic calibration module of the system is designed to maintain the calibration of stereo cameras regardless of their configuration or position, resulting in accurate and continuous depth perception.

Sensor fusion allows the accurate detection of obstacles in adverse weather and lighting situations.

This patent serves as the foundation for the Company's main product, the QuadSight® vehicle vision system. QuadSight® combines reflected light from visible-light cameras with thermal energy acquired by long-wave infrared cameras to provide robust, precise object detection in all weather and lighting circumstances, including total darkness, rain, haze, fog, and glare. Foresight’s four-camera vision system is ideal for semi-autonomous and autonomous cars.
