Abstract: A method of instance segmentation in an image and a system for instance segmentation of images. The method includes identifying, with a processor, a starting pixel associated with an object in an image, the image having a plurality of rows of pixels, the starting pixel located in a row of the plurality of rows; identifying, with the processor, at least one pixel located in an adjacent row to the row in which the starting pixel is located, the at least one pixel being part of the same object as the starting pixel; iterating the previous two identification steps using the at least one identified adjacent row pixel as a start pixel for the next iteration; and connecting, with the processor, the at least one identified adjacent row pixels to form polylines representing the object.

Abstract: Systems and methods for estimating a length of at least a portion of a trailer that is carried by a tractor. The tractor has a fifth wheel coupling that is configured to be connected to a kingpin of the trailer. The height of the fifth wheel coupling is adjustable by adjustment of an angle of a boom that carries the fifth wheel coupling. The angle of the boom is determined by a sensor. The angle of the trailer is determined by a sensor. The length of at least a portion of the trailer is calculated based on the boom length, the determined boom angle, and the determined trailer angle.

Abstract: A system and method for automatically coupling at least one of an air line or an electrical line of a tractor to a trailer that is configured to be pulled by the tractor. A moveable arm is mounted to the tractor and is configured to exhibit at least one degree of freedom (DOF) of motion relative to the tractor. The moveable arm carries at least one of an air line connector or an electrical connector. A trailer coupling head is mounted to the trailer and carries at least one of an air line connector or an electrical connector that are configured to be connected to the at least one of an air line connector or an electrical connector of the tractor. The trailer coupling head can be moved in at least a vertical DOF relative to the ground by the automatic coupling system.
