  • Patent number: 11733041
    Abstract: An apparatus and method are presented comprising one or more sensors or cameras configured to rotate about a central motor. In some examples, the motor is configured to travel at a constant linear speed while the one or more cameras face downward and collect a set of images in a predetermined region of interest. The apparatus and method are configured for image acquisition with non-sequential image overlap. The apparatus and method are configured to eliminate gaps in image detection for fault-proof collection of imagery for an underwater survey. In some examples, long baseline (LBL) is utilized for mapping detected images to a location. In some examples, ultra-short baseline (USBL) is utilized for mapping detected images to a location. The apparatus and method are configured to utilize a simultaneous localization and mapping (SLAM) approach.

  • Patent number: 10183732
    Abstract: Optical detectors and methods of optical detection for unmanned underwater vehicles (UUVs) are disclosed. The disclosed optical detectors and may be used to dynamically position UUVs in both static-dynamic systems (e.g., a fixed light source as a guiding beacon and a UUV) and dynamic-dynamic systems (e.g., a moving light source mounted on the crest of a leader UUV and a follower UUV).

  • Patent number: 9812018
    Abstract: A system and method for optical communication between multiple UUVs, more specifically, for leader-follower formations between UUVs. The system focuses on the characterization and modeling of a 1-dimensional and/or 3-dimensional light field produced from a light source mounted on a Leader UUV, which is detected by one or more follower UUVs. Communication algorithms are used to monitor the UUV's motion and orientation utilizing simulators, look up tables, and the like. A variety of detectors arrays can be used in a variety of wavelengths depending on the desired application.
