Field: Measurement (Instruments)
Classification: CPC A  G | IPC A  G

Claim 0:
1. A system for guiding an agricultural vehicle comprising:
at least one distance sensor configured for coupling with the agricultural vehicle, the at least one distance sensor configured to conduct scans, each scan includes a plurality of scan lines and a distance measurement along each scan line of the plurality of scan lines to monitor a plurality of distances of at least one crop row, the at least one crop row including:
a first edge of the at least one crop row; and
a second edge of the at least one crop row; and

a controller in communication with the at least one distance sensor, the controller includes:
a comparator module configured to compare values corresponding to the monitored plurality of distances of the at least one crop row from the plurality of scan lines of each scan, comparing values includes:
generating an array of standard deviations based on the plurality of distances including one or more standard deviation couplets, each standard deviation couplet having a first standard deviation of a first subset of the plurality of distances and a second standard deviation of a second subset of the plurality of distances;

an identification module configured to identify the first and second edges of the at least one crop row based on the compared values; and
a navigation module configured to guide the agricultural vehicle according to one or more of the identified first or second edges of the at least one crop row.
