A system includes a processor and a memory. The memory stores instructions executable by the processor to detect an occlusion on a surface in a vehicle sensor optical path based on a segmentation of sensor image data, and to select a cleaning plan for the surface based on the detected occlusion, map data, and vehicle route data.

A sensor having a positive temperature coefficient shroud is described, as well as a computing system to control actuation of the positive temperature coefficient shroud. According to one example, the computing system executes a method that actuates the positive temperature coefficient shroud of the sensor based on a transmittance parameter of the sensor.

An occluded area on a vehicle sensor is identified by localizing the vehicle in space. A discrepancy between historic image data and real-time image data from the sensor is determined, and a cleaning actuator is actuated based on the determined discrepancy.

A system mounted on a vehicle for detecting an obstruction on a surface of a window of the vehicle, a primary camera is mounted inside the vehicle behind the window. The primary camera is configured to acquire images of the environment through the window. A secondary camera is focused on an external surface of the window, and operates to image the obstruction. A portion of the window, i.e. window region is subtended respectively by the field of view of the primary camera and the field of view of the secondary camera. A processor processes respective sequences of image data from both the primary camera and the secondary camera.

An apparatus includes a camera lens assembly and a printed circuit board attached to said camera lens assembly. The camera lens assembly may be configured to provide a forward view through a windshield of a vehicle. The printed circuit board generally comprises an antenna, a ground plane, and an image sensor. The antenna is generally disposed on a front surface of the printed circuit board. The ground plane may be disposed either on the front surface or within a layer of the printed circuit board. The image sensor is generally mounted on a back surface of the printed circuit board. The camera lens assembly is generally configured to focus an image of the forward view through the windshield on the image sensor.

The present disclosure relates to a speckles detection system for detecting one or more speckles on a surface of an optical element of an image capturing device. The system comprises: one or more light sources configured to emit a light beam towards the optical element, the optical element being configured to reflect light from the light sources when speckles are located on the surface of the optical element. The system further comprises one or more light receivers configured to receive the light beam reflected by the optical elements such that speckles on the surface of the optical elements are detected. Methods for detecting one or more speckles on a surface of an optical element of an image capturing device are also provided.

A vehicle includes: a front camera configured to capture an image in front of the vehicle through a windshield of the vehicle; a front visibility recognition unit configured to recognize a degree of deterioration of front visibility through the windshield based on captured image of the front camera; a foreign object removing unit configured to remove a surface abnormality of a rear window that deteriorates rear visibility through the rear window of the vehicle; and a rear visibility control unit configured to operate the foreign object removing unit to remove the surface abnormality of the rear window based on the degree of deterioration of the front visibility.

An apparatus includes an interface and a processor. The interface may be configured to receive video frames comprising at least one of a vehicle or an outdoor environment near the vehicle and a correction signal. The processor may be configured to perform video operations on the video frames to detect objects, predict a state of the vehicle based on the objects detected in the video frames and generate the correction signal. The correction signal may be configured to apply a corrective measure based on the predicted state of the vehicle. The state of the vehicle may be predicted when the vehicle is parked in the outdoor environment. The state of the vehicle may comprise factors that prevent driving the vehicle.

A system includes a computer programmed to receive image data of an exterior of a vehicle from an external image device. The computer is further programmed to, upon determining that a difference between the received image data and stored baseline image data exceeds a threshold, actuate the vehicle to navigate to a car wash location.
