Abstract: In a mobile equipment with an articulated front portion having a worktool, a fisheye camera with a wide field of view, containing the front portion, is often mounted in a fixed direction on a rear portion of the mobile equipment. Thus, when the front portion moves (e.g., rotates) relative to the rear portion, a view around the front portion may be compromised due to inherent cropping in fisheye-distortion correction. Digital panning of panoramic video is disclosed that rotates a projection surface, in accordance with movement of the front portion, and generates a projected video on the projection surface, utilizing information that may have otherwise been cropped, to expand the visible area around the worktool. The digital panning in the projected video may mimic an operator turning their head to look down the longitudinal axis of the front portion while using the worktool.

Abstract: The present disclosure is directed to systems and methods for managing on-site communications of a machine with a latency-dependent application installed. The method includes, for example, (i) receiving geographical information associated with a work site; (ii) receiving historical communications information associated with the work site; (iii) analyzing the historical communications information and the geographical information; (iv) generating an instruction for implementing the latency-dependent application of the machine based on a latency requirement of the latency-dependent application; and (v) implementing the latency-dependent application of the machine based on the instruction. The historical communications information includes a communications event, a duration of the communications event, and a frequency of the communications event.
