Embodiment Construction

[0035] A camera mounting structure for a vehicle is disclosed that attaches the camera to the vehicle at a mounting point, isolates the camera from vehicle vibrations, and accommodates thermal expansion and contraction of the mounting structure relative to the vehicle. The position of each camera and the angle at which each camera is pointed (eg, azimuth and elevation) affect the images collected by the cameras, and any changes will affect the images captured by the cameras. These changes should be accounted for or corrected for under all operating conditions, including a wide range of temperatures, shocks, and vibrations. For example, in autonomous driving applications, pictures collected by vehicle-mounted cameras are used by various driving and safety algorithms, and thus changes in the images can affect vehicle safety. The vehicle may vibrate in one or more dimensions (such as laterally from side to side, laterally from front to rear, and vertically up and down). Some veh...

Abstract

Disclosed is a camera mounting apparatus for a vehicle that attaches the camera to the vehicle, isolates the camera from vibration at the mounting points, and accommodates thermal expansion and contraction of the vehicle and the mounting structure. The apparatus includes a camera mounting beam coupled to the camera, and one or more elastomeric vibration isolators coupled to an attachment device and coupled to the camera mounting beam. The apparatus also includes a spherical bearing coupled to the attachment device, wherein the spherical bearing is configured to accommodate misalignment of theattachment device, and one or more spring washers to generate a force holding the one or more elastomeric vibration isolators and spherical bearing in positions.

Description

technical field [0001] This document relates to camera housings for vehicles such as autonomous trucks. Background technique [0002] Vehicles may include attached cameras. For example, cameras can be attached for safety purposes, as a driving aid or to facilitate autonomous driving. Vehicles vibrate due to engine vibration, road, air turbulence, and wind vibrations. These vehicle vibrations can be introduced into camera images, resulting in image degradation. Additionally, thermal effects can cause the camera mounting system to change where the camera is pointed as temperature changes. Existing technologies are expensive and inefficient. In order to reduce the cost and improve the stability of the vehicle mounted camera mounting structure, new technologies are required. Contents of the invention [0003] An apparatus, system, and method for mounting one or more cameras to a vehicle that maintains the pointing angle of the cameras and reduces vehicle-induced camera vi...
