    Abstract: A method for tracking workers at a worksite is disclosed. The method includes acquiring a video of the worksite and detecting a movement of objects in the video. Each object is represented by a plurality of pixels. The method includes identifying an item associated with at least one object by clustering a set of pixels of the plurality of pixels based on a color of the set of pixels. Next, the method includes determining the item as a hard hat based on at least a shape of the set of pixels, and identifying the object as a specific worker based on the color of the set of pixels. The method also includes generating a movement data associated with the specific worker based on a tracking of the hard hat.

    Abstract: A method for loading a payload carrier of a machine includes receiving, from a camera on the machine, a two-dimensional image of an interior of the payload carrier as material is loaded into the payload carrier. The method further includes filtering the image to identify a contour of the loaded material and determining an area of the contour. The method further includes controlling a display device indicate the determined area.

    Abstract: A wear estimation system for a component of a machine includes a geolocation unit, a non-transitory computer-readable medium bearing a component wear estimate program, a controller, and an interface device. The geolocation unit is configured to generate a location signal indicative of a location of the machine. The controller is in operable communication with the geolocation unit to receive the location signal therefrom and is configured to execute the component wear estimate program. The interface device is configured to display a graphical user interface of the component wear estimate program. The component wear estimate program is configured to determine an estimated part life for the component based upon an environmental characteristic of the location; to track an actual usage amount for the component; and to indicate, through the graphical user interface, when the usage amount of the component exceeds a threshold percentage of the estimated part life.

    Abstract: A method for loading a payload carrier of a machine includes receiving, from a camera on the machine, a two-dimensional image of an interior of the payload carrier as material is loaded into the payload carrier. The method further includes sectioning the two-dimensional image into a plurality of regions, and determining, for individual of the regions, whether the region includes a representative of fill material. The method may also include determining a fill volume based on the regions having fill and those not having fill.
