Abstract
The invention provides an autonomous vehicle with a video camera that merges images taken a different light levels by replacing saturated parts of an image with corresponding parts of a lower-light image to stream a video with a dynamic range that extends to include very low-light and very intensely lit parts of a scene. The high dynamic range (HDR) camera streams the HDR video to a HDR system in real time—as the vehicle operates. As pixel values are provided by the camera's image sensors, those values are streamed directly through a pipeline processing operation and on to the HDR system without any requirement to wait and collect entire images, or frames, before using the video information.
Claims15
An HDR system comprising:
- an HDR camera operable to produce a real-time HDR video;
- and
- a processing system configured to communicate with the HDR camera and a control system of a vehicle, wherein the processing system is operable to determine, based on the HDR video, a characteristic of a feature in the vehicle's environment and to issue to the control system an instruction that directs a change in the operation of the vehicle based on the characteristic.
