1. A kernel-level grain monitoring system utilized onboard a combine harvester, the kernel-level grain monitoring system comprising:
a grain camera positioned to capture bulk grain sample images of a currently-harvested grain taken into and processed by the combine harvester;
a moisture sensor configured to generate moisture sensor data indicative of a moisture level of the currently-harvested grain;
a display device having a display screen on which one or more parameters pertaining to the currently-harvested grain are selectively presented; and
a controller architecture coupled to the grain camera, to the moisture sensor, and to the display device, the controller architecture configured to:
analyze the bulk grain sample images, as received from the grain camera, to determine an average per kernel (APK) volume representing an estimated volume of a single average kernel of the currently-harvested grain;
calculate one or more topline harvesting parameters based, at least in part, on the determined APK volume and the moisture sensor data; and
selectively present the topline harvesting parameters on the display device for viewing by an operator of the combine harvester;
wherein the topline harvesting parameters include a kernel weight parameter having a test weight specifying a weight of the currently-harvested grain when packed into a predetermined volume of space; and
wherein the controller architecture is further configured to calculate the test weight utilizing kernel packing data indicating a cumulative void space within the predetermined volume of space.
