1results about How to "Accurate navigation information" patented technology

This invention discloses a vehicle navigation system for improving driving safety, comprising a sensor, an optical signal processing device, and a navigation device. The sensor is disposed near a vehicle window, which includes at least the windshield and optionally further includes side windows. The sensor collects optical signals within the window's field of view. The optical signal processing device processes the optical signals to obtain a clear image of the window's field of view after removing the effects of scattered light. The navigation device feeds navigation information to the driver or navigation data to an autonomous driving system based on the information from the image after removing the effects of scattered light. This invention can provide navigation information based on a clear image of the window's field of view in low-visibility environments, thereby improving driving safety in low-visibility conditions.
