Abstract: This disclosure relates to a system for scanning crops. A line scan distance sensor measures a distance of the crops from the sensor and generates distance data indicative of the distance of the crops from the sensor at a measurement angle. A mover system moves the line scan distance sensor or the crops perpendicular to the distance of the crops from the sensor. A rotary encoder associated with the mover system generates movement data indicative of a movement of the distance sensor or the crops perpendicular to the distance of the crops from the sensor. A data collector associates the distance data from the distance sensor with relative positioning data based on the movement data from the rotary encoder and stores the distance data associated with the relative positioning data on a data store. The system allows accurate relative spatial alignment of sequential line scans. As a result, an extremely high resolution in the direction of movement can be achieved.
