Abstract
A work machine includes a frame, a linkage assembly, a work implement connected to the linkage assembly, and a grade control calibration system. The grade control calibration system includes a vision processing system, which includes a sensor fixed to the linkage assembly and a first controller. The vision processing system is configured to measure a length of a cutting portion of the work implement, and to transmit the length of the cutting portion of the work implement. The grade control calibration system also includes a grade control system in communication with the vision processing system and the linkage assembly. The grade control system includes a second controller configured to receive the length of the cutting portion of the work implement from the first controller, and to calibrate a position of the work implement based on the received length of the cutting portion of the work implement.
