摘要： A marine vessel management system, comprising: receiving input data comprising at least radar input data indicative of a first field of view and imagery input data indicative of a second field of view being at least partially overlapping with said first field of view. Processing the input data to determine data indicative of reflecting object(s) within an overlapping portion of said first field of view. Determining respective locations(s) within said second field of view, where said reflecting object(s) are identified, and obtaining radar meta-data of said reflecting object(s); processing said input imagery data said respective locations in an overlapping portion of said second field of view. Determining image data piece(s) corresponding with section(s) of said imagery data associated with said reflecting object(s). Using said radar meta-data for generating label data and generating output data comprising said image data section(s) and said label data.

摘要： A method for steering an Autonomous Underwater Vehicle along an object buried below a seabed: the AUV being equipped with at least one acoustic transmitter for generating acoustic signal towards the buried object and the seabed; arranging a first sensor assembly substantially flush with the AUV hull of the starboard side of the AUV for recording reflected acoustic signal from the buried object and the seabed with the first sensor assembly comprising one or more acoustic sensors, arranging a second sensor assembly substantially flush with the AUV hull of the port side of the AUV for recording reflected acoustic signal from the buried object and the seabed with the second sensor assembly comprising one or more acoustic sensors, generating an acoustic signal with a center frequency range between 1 kHz and 24 kHz with the at least one acoustic transmitter, recording reflected energy from the seabed and recording reflected energy from the buried object with the first and second sensors, registering reflected energy from the buried object in the recorded reflected energy data provided by the first and the second sensors and distinguishing the buried object from the seabed as the later arrival of the reflected energy of the seabed and the buried object, determining which of starboard and port side the object lies relative the AUV by determining which sensor assembly receiving the reflected energy data from the buried object first, and navigating the AUV towards the buried object based on which of starboard and port side the object lies relative the AUV.

摘要： In a mobile robot, a control unit performs movement control for moving toward a target direction while remaining in a movable region representing a communicable region without a collision between an own robot and another robot. A movable region calculation unit calculates, from a state of the own robot and a state of the other robot, a first region where the own robot and the other robot do not collide, a second region where the own robot and the other robot are capable of communicating, and the movable region in which the first region and the second region overlap.

摘要： A method of training a machine learning, ML, algorithm to control a watercraft is described. The watercraft is a submarine or a submersible submerged in water. The method is implemented, at least in part, by a computer, comprising a processor and a memory, aboard the watercraft. The method comprises: obtaining training data including respective sets of environmental parameters and corresponding actions of a set of communicatively isolated watercraft, including a first watercraft; and training the ML algorithm comprising determining relationships between the respective sets of environmental parameters and the corresponding actions of the watercraft of the set thereof. A method of controlling a watercraft by a trained ML algorithm is also described.

摘要： A suspended self-balancing self-cruising online water quality monitoring device, an online water quality monitoring method, and an online water quality assessment method are provided. The device includes a suspension cabin main body, a communication and control system, and a suspended carrying platform configured for self-balancing attitude adjustment. Suspension feet configured to drive the suspension cabin main body to implement self-balancing attitude adjustment, cruising, or fixed-point suspension are arranged outside the suspension cabin main body. The communication and control system is configured to plan a W-shaped water-region cruising path and sampling points thereon according to a topography of a water region, control the water sample testing device to test quality of water along the sampling points online, assess water quality of the water region according to an online testing result, and output the water quality of the water region. The device achieves precise positioning and self-cruise monitoring are achieved.
