Abstract
Systems and techniques for refined row guidance parameterization with Hough transform are described herein. An electronic representation of a field (ERF) can be received. A steering variable calculation can be performed by executing a cascaded Hough transform on the ERF. An intermediate value used in calculating the steering variable can be selected. A refined intermediate value can be identified from the intermediate value by measuring a difference between the intermediate value and an anchor value. The steering variable calculation can be adjusted using the refined intermediate value
Claims27
A machine-readable medium that is not a transitory propagating signal, the machine-readable medium including instructions that, when executed by a machine, cause the machine to perform operations comprising:
- receiving an electronic representation of a field (ERF);
- performing a steering variable calculation by executing a cascaded Hough transform on the ERF;
- selecting an intermediate value used in calculating the steering variable;
- identifying a refined intermediate value from the intermediate value by measuring a difference between the intermediate value and an anchor value;
- and
- adjusting the steering variable calculation using the refined intermediate value.
A machine-implemented method comprising:
- receiving an electronic representation of a field (ERF);
- performing a steering variable calculation by executing a cascaded Hough transform on the ERF;
- selecting an intermediate value used in calculating the steering variable;
- identifying a refined intermediate value from the intermediate value by measuring a difference between the intermediate value and an anchor value;
- and
- adjusting the steering variable calculation using the refined intermediate value.
A system comprising:
