Cone-textured glare shield for enhanced camera vision

Abstract

The present disclosure pertains to a glare shield designed to enhance the performance of vehicle camera systems, particularly those used in autonomous and semi-autonomous vehicles. The glare shield features a textured surface composed of an array of micro-cones, or cone-shaped formations, which serve to scatter incident light in various directions, thereby reducing glare and improving camera vision. The micro-cones are optimized in size, angle, and orientation to minimize Total Hemispherical Reflectance (THR) and reflection penalty, enhancing the camera's ability to accurately interpret visual data. Additionally, the glare shield may include an electromechanical system for dynamic orientation adjustment in response to the position of external light sources, such as the sun. The manufacturing process of the glare shield utilizes a sintered tool steel insert, facilitating venting during molding and ensuring the precision of the cone-shaped texture.
