Camera systems using filters and exposure times to detect flickering illuminated objects
First Claim
1. A method comprising:
- capturing images using a first camera and a first exposure time, the first camera being mounted in order to capture images of an environment, the first camera being without an ND filter;
capturing images using a second camera and a second exposure time, the second camera being mounted in order to capture images of the environment, the second exposure time being greater than or equal to the first exposure time and having an ND filter;
using the images captured using the second camera to identify illuminated objects;
using the images captured using the first camera to identify the locations of objects; and
using the identified illuminated objects and identified locations of objects to control a vehicle in an autonomous driving mode.

Abstract
The technology relates to camera systems for vehicles having an autonomous driving mode. An example system includes a first camera mounted on a vehicle in order to capture images of the vehicle'"'"'s environment. The first camera has a first exposure time and being without an ND filter. The system also includes a second camera mounted on the vehicle in order to capture images of the vehicle'"'"'s environment and having an ND filter. The system also includes one or more processors configured to capture images using the first camera and the first exposure time, capture images using the second camera and the second exposure time, use the images captured using the second camera to identify illuminated objects, use the images captured using the first camera to identify the locations of objects, and use the identified illuminated objects and identified locations of objects to control the vehicle in an autonomous driving mode.
