摘要： Techniques are disclosed for systems and methods to provide passage planning for a mobile structure. A passage planning system includes a logic device configured to communicate with a user interface associated with the mobile structure and at least one operational state sensor mounted to or within the mobile structure. The logic device determines an operational range map based, at least in part, on an operational state of the mobile structure, potential navigational hazards, and/or environmental conditions associated with the mobile structure. Such operational range map and other control signals may be displayed to a user and/or used to generate a planned route and/or adjust a steering actuator, a propulsion system thrust, and/or other operational systems of the mobile structure.

摘要： Techniques are disclosed for systems and methods for video based sensor fusion with respect to mobile structures. A mobile structure may include at least one imaging module and multiple navigational sensors and/or receive navigational data from various sources. A navigational database may be generated that includes data from the imaging module, navigational sensors, and/or other sources. Aspects of the navigational database may then be used to generate an integrated model, forecast weather conditions, warn of dangers, identify hard to spot items, and generally aid in the navigation of the mobile structure.

摘要： Systems and methods to provide wildlife feeding flock detection using a remote sensing imagery system. The system 100 includes a radar 160 assembly mounted to a mobile structure 101 and a coupled logic device. The logic device is configured to receive radar returns corresponding to a detected target, determine a radial velocity spectrum associated with the detected target based, at least in part, on the received radar returns. The process determining a probability the detected target includes a feeding flock based, at least in part, on the determined radial velocity spectrum. The logic device generates radar image data based on the received radar returns, the determined radial velocity spectrum, and/or the probability the detected target includes the feeding flock. Determining the radial velocity spectrum preferably involves determining a centroid range and centroid azimuth relative to the radar assembly and determining an azimuth segmented velocity spectrum and a range segmented velocity spectrum. The determination of the probability the target comprises a feeding flock preferably comprises determining a breadth, differentiation, mean, standard deviation and/or skewness of an azimuth segmented velocity spectrum and/or the range segmented velocity spectrum.

摘要： Techniques are disclosed for systems and methods for providing a fused image that combines image data of a scene received from an imaging system with a chart to aid in the navigation of a mobile structure. Specifically, the fused image may be generated by superimposing various image elements extracted from an image onto various locations on the chart that correlate to the actual positions of the objects within the scene. In some embodiments, one or more non-water objects may be detected within the image, image representations of the non-water objects may be extracted from the image feed, and the extracted image representations may be superimposed onto locations on the chart that are determined to correlate to the actual positions of the non-water objects within the scene.

摘要： A system 100B to provide navigation control and/or docking assist for a marine vessel 101. A user input 120/130 device receives navigation control parameters input by a user, such as a target docking position, track, destination or orientation of a boat 101. A perimeter ranging system 148a,b, which may include sensors such as an ultrasonic sensor array, radar systems, visible spectrum and/or infrared/thermal imaging modules or cameras or LIDAR systems, is used to detect collision hazards within the vicinity of the vessel. A processor receives the user input destination and perimeter sensor data, and outputs control signals to a collision avoidance thruster 172 or steering actuator 150, the control signals manoeuvre the yacht into the desired position whilst evading objects in or on the water that pose a collision risk. Preferably, a 2D map is generated, the map displays areas/regions where a risk of collision has been detected, each area is assigned a thruster or velocity demand to limit the thrust/velocity to minimise a risk of collision. A cost function / linear regression model may be used to determine an optimal thrust/velocity attenuation based on an estimated collision risk. Preferably, voxels / volumetric pixels are used to estimate collision risk, wherein overlapping voxels are assigned a weighting according to set criteria.

摘要： An imaging device (e.g. 360-view camera system and/or an infrared camera) provides images of an environment. An object is detected within the image and a portion of the image associated with the object is superimposed on a chart projected on a surface. A representation of the object (e.g. an icon or image element extracted from the image) is superimposed onto the projected chart at a location corresponding to a geographical position of the object. The resulting fused image corresponds to an area surrounding a mobile structure as viewed from a synthetically elevated viewpoint. A logic device determines a distance between the mobile structure and object and determines the location on the projected chart that describes that geographical position of the object based on the synthetically elevated viewpoint and the camera viewpoint. The logic device may also correct an orientation of the received image.

摘要： Systems and methods for ultrasonic perimeter ranging sensors 448 including a perimeter ranging system having one or more ultrasonic perimeter ranging sensor assemblies connectable to a mobile structure 101. A logic device is configured to communicate with the ranging system and receive perimeter sensor data from each sensor and generate an obstruction map based at least in part on the perimeter sensor data. The logic device may determine a range and/or relative velocity of a navigation hazard 401 within the monitoring perimeter of the ranging system based on the received perimeter sensor data. The logic device may then generate a display map of the perimeter data and determine navigational control signals based on the identified navigation hazard, the control signal may be displayed to a user or used to automatically adjust the mobile structures controls. The system may also identify a portion of the mobile structure in the perimeter sensor data and use this data to determine the relative orientation and/or position of the sensor on the mobile structure using the identified portion.
