US 12,217,507 B2 · Vehicle monitoring method and monitoring system

Abstract

Provided are a vehicle monitoring method and a vehicle monitoring system. The vehicle monitoring method includes that: a polarization angle of polarized light in a sky image reflected by a vehicle window in a monitoring scenario is calculated, and a light-filtering polarization angle is calculated according to the polarization angle of the polarized light in the sky image reflected by the vehicle window, where the polarized light in the sky image is formed by scattered sunlight in a sky region corresponding to the sky image; the polarized light in the sky image reflected by the vehicle window in the monitoring scenario is filtered out according to the light-filtering polarization angle; and the monitoring scenario is imaged to form a monitoring image.
