Abstract: Techniques are disclosed for systems and methods for water non-water segmentation of navigational imagery to assist in the autonomous navigation of mobile structures. An imagery based navigation system includes a logic device configured to communicate with an imaging module coupled to a mobile structure and/or configured to capture images of an environment about the mobile structure. The logic device may be configured to receive at least one image from the imaging module; determine a water/non-water segmented image based, at least in part, on the received at least one image, and generate a range chart corresponding to the environment about the mobile structure based, at least in part, on the determined water/non-water segmented image and/or the received at least one image.

Abstract: Bird's eye view (BEV) semantic mapping systems and methods are provided. A method includes receiving an image captured by a monocular camera having a first point of view (POV) of an environment including a plurality of features. The method further includes processing, by an artificial neural network (ANN), the captured image to generate a semantic map for the captured image, the semantic map associated with a second POV different from the first POV. The features exhibit a uniform scale in the semantic map. Additional methods and associated systems are also provided.

Abstract: Techniques are disclosed for systems and methods to provide extrinsic sensor calibration for mobile structures. A sensor calibration system includes first and second sensors coupled to a mobile structure and a logic device. The logic device is configured to receive first and second series of pose measurements corresponding to sensor data provided by the respective first and second sensors, determine a set of intermediate calibration transformation estimates corresponding to the first and second sensors based, at least in part, on a scale-dependent calibration error function and/or the first and second series of pose measurements, and determine an ongoing calibration transformation estimate corresponding to the first and second sensors based, at least in part, on the determined set of intermediate calibration transformation estimates.

Abstract: A wrapping paper for a roll having two opposed roll ends, the wrapping paper includes: a paper layer; and at least one exposed strip having adhesive properties. The at least one exposed strip is proximate to a side edge of the paper layer and covers at least a portion of one of the roll ends when wrapped around the roll. A method for wrapping a roll having a pair of spaced roll ends and an outer roll surface extending between the roll ends.
