Systems and methods are disclosed for lens water dispersion. For example, an image capture device may include a lens mounted on a body of the image capture device; an image sensor mounted within the body, behind the lens and configured to detect images based on light incident on the image sensor through the lens; and a dispersion structure around a perimeter of the lens on an external surface of the body, wherein the dispersion structure includes gaps sized to cause capillary action to move water away from the lens, from a first edge of the dispersion structure to a second edge of the dispersion structure.

A camera apparatus includes a disk-shaped base portion having a hook portion and fixed to a fixed surface and, an apparatus main body mounting a camera portion and a connector, having a base hinge to be locked to the hook portion, and suspended from the base portion by locking the base hinge to the hook portion, an engagement mechanism engaging the apparatus main body and the base portion such that the apparatus main body and the base portion are not able to be separated from each other in a state that the apparatus main body is rotated in a direction approaching the base portion with the hook portion locking the base hinge as a fulcrum and the apparatus main body is parallel to the base portion, and a dome cover assembly watertightly covering the camera portion and the connector and attached to the apparatus main body.

A sensor unit to be mounted on a vehicle, the sensor unit includes: a LiDAR; a housing configured to accommodate the LiDAR; and a cleaner attached to the housing and including a first nozzle configured to jet air at a first surface to be cleaned corresponding to the LiDAR and a second nozzle configured to jet a cleaning liquid at the first surface to be cleaned. The first nozzle is disposed above the second nozzle, a jetting direction of the air from the first nozzle is a direction that is parallel to a horizontal direction or a direction that is more downward-trending than the horizontal direction, and a jetting direction of the cleaning liquid from the second nozzle is a direction that is more upward-trending than the horizontal direction.

A computerized system of performing fish census which otherwise requires high level of domain knowledge and expertise is described. Divers with minimal knowledge of fish can obtain high quality population and species distribution measurements using a stereo camera rig and fish video analyzer software that was developed. The system has two major components: a camera rig and software for fish size, density and biomass estimation. The camera rig consists of a simple stand on which one to four pairs of stereo cameras are mounted to take videos of the benthic floor for a few minutes. The collected videos are uploaded to a server which performs stereo analysis and image recognition. The software produces video clips containing estimates of fish size, density and species biodiversity and a log report containing information about the individual fishes for further end user analysis.

An on-board sensor cleaning device includes nozzle ports. The on-board sensor cleaning device ejects fluid from the nozzle ports in a predetermined order to clean a sensing surface of an on-board sensor.

A method for removing foreign substances from a camera system is provided. The camera system includes a camera device with a transparent cover having a piezoelectric component. First, a type of the foreign substances is identified based on temperature, an image captured by the camera system, and a voltage change of the piezoelectric component. A sequence of frequencies is applied to the piezoelectric component and a resonant frequency is acquired. Thereafter, the foreign substances are removed from the camera system. A vibration frequency and a vibration time period for the piezoelectric component are determined according to the identified type of the foreign substances. The vibration frequency is based on the resonant frequency. The piezoelectric component is driven with the vibration frequency and the vibration time period, such that at least a portion of the foreign substances are removed from the transparent cover through vibration of the piezoelectric component.

A system and method for displaying elevated, polarized views of water bodies are provided. The system and method of the present disclosure are generally designed to obtain images from a vantage point located at a first location and subsequently transmit and display the same to an individual located at a second location. To this end, the system and method of the present disclosure may comprise a camera, a mounting device, and a display operably connected to the camera. The mounting device may be used to attach the camera in an elevated position on a boat to enable the camera to capture video images of the body of water surrounding the boat. To reduce glare on the body of water, the camera may have a polarized filter. Video images captured by the camera are transmitted to the display for display thereon in real time.
