Claim:
1. A method for in-situ precision agriculture calibration of a device during operation of the device within a field, the method comprising: capturing a first image of a first field region with a first camera of the device; setting, by a computer of the device, a target treatment boundary location in the first field region based on the first image, the target treatment boundary location set in the first field region between a first treatment area and a second treatment area; controlling, by the computer, a treatment mechanism of the device to apply the first treatment to the first treatment area; controlling, by the computer, the treatment mechanism of the device to apply the second treatment to the second treatment area at a transition time, wherein the transition time is based on the target treatment boundary location; capturing a second image of a second field region with a second camera of the device after the transition time, wherein the second field region overlaps with at least a portion of the first field region, the overlapped portion including the target treatment boundary location, and at least a portion of the first and second treatment areas, and the second camera being fixed on the device a predetermined separation distance away from the first camera along a traversal axis of the device; determining, by the computer, an actual treatment boundary location based on the second image and a motion of the device, wherein the actual treatment boundary location is a location in the first field region where application of the second treatment begins; and calibrating, by the computer, the device based on the target treatment boundary location and the actual treatment boundary location.
