摘要： In some examples, a processor may receive images from a camera mounted on a vehicle. The processor may generate a disparity image based on features in at least one of the images. In addition, the processor may determine at least one region in a first image of the received images that has a brightness that exceeds a brightness threshold. Further, the processor may determine at least one region in the disparity image having a level of disparity information below a disparity information threshold. The processor may determine a region of light interference based on an overlap between at least one region in the first image and at least one region in the disparity image, and may perform at least one action based on the region of light interference.

摘要： In some examples, a first electronic control unit (ECU) receives zone sensor data of a plurality of zones associated with a vehicle. For instance, a respective second ECU and a respective set of zone sensors is associated with each respective zone of the plurality of zones. Based on an indicated driving mode of the vehicle, the first ECU may perform recognition on the zone sensor data from a first zone of the plurality of zones to determine first recognition information. The first ECU receives second recognition information from the respective second ECUs of the respective zones. For instance, the respective second ECUs are configured to perform recognition processing on respective zone sensor data from the set of zone sensors of the respective zones. Based on the first recognition information and the second recognition information, the first ECU sends at least one control signal to at least one vehicle actuator.

摘要： A system for dynamic image compression in autonomous vehicles with multiple cameras. The cameras of a vehicle may be prioritized based on various features, and different image compression techniques may be assigned to different cameras in the vehicle, based on the priorities of the cameras, to reduce overall processing load of the vehicle.
