摘要： Liquid cleaning systems for cleaning AV sensors are disclosed herein. An example liquid cleaning system includes a reservoir storing a liquid. The liquid can flow from the reservoir to a heat exchanger. The heat exchanger can transfer heat generated by a part of the AV to the liquid, thereby improving cleaning efficacy. The part may be battery, motor, engine, sensor (e.g., the sensor to be cleaned with the liquid or another sensor), etc. The heat may be an unintended product of an operation of the part. The heat exchanger can use the heat to warm up the liquid and cool down the part. Additionally or alternatively, the liquid can be heated by another heat exchanger or a heater. The heater can generate heat intended for heating the liquid. The heater may be local to the sensor to be cleaned, e.g., the heater is closer to the sensor than the reservoir.

摘要： Methods and systems are provided for preserving dynamic range in images. In some aspects, a process can include steps for receiving, at an autonomous vehicle system, image data from an image sensor, generating, by the autonomous vehicle system, a high dynamic range (HDR) output by performing HDR processing on the image data from the image sensor, generating, by the autonomous vehicle system, a least significant bit (LSB) output by performing LSB processing on the image data from the image sensor, and generating, by the autonomous vehicle system, an 8-bit output by performing a buffer process on the HDR output and the LSB output of the image sensor.

摘要： Systems and methods are provided for a baffle assembly for an optical sensor. In one aspect, the baffle assembly is coupled to an optical sensor that is mounted on an autonomous vehicle. The baffle assembly can include a baffle housing coupled to the optical sensor at a proximal edge, and configured to at least partially enclose a field of view of the optical sensor. Additionally, the baffle assembly may include one or more nozzles that are configured to project fluid toward a surface of a lens of the optical sensor.
