A camera calibration tool for calibrating one or more cameras of a mobile machine comprising calibration targets and a net. Each of the calibration targets comprises identifiable indicia. The net is adapted to be coupled to the mobile machine. The net has one or more configurations that define predetermined target locations, with location markers, in a predetermined layout. The calibration targets are positioned respectively at the predetermined target locations in the predetermined layout to calibrate the one or more cameras by use of the calibration targets.

Camera calibration tool

An upper point cloud estimator is configured to estimate a three-dimensional representation of the crop canopy based on collected stereo vision image data. A lower point cloud estimator is configured to estimate a ground three-dimensional representation or lower point of the ground based on the determined average. The electronic data processor is configured to determine one or more differences between the upper point cloud (or upper surface) of the crop canopy and a lower point cloud of the ground, where each difference is associated with a cell within a grid defined by the front region. The electronic data processor is capable of providing the differences to a data processing system to estimate a yield or differential yield for the front region, among other things.

Method for controlling a vehicle for harvesting agricultural material

A computer-implemented method includes obtaining harvest data indicative of a prior harvesting operation on a field, identifying a region of the field having already-harvested crop plants based on the harvest data, detecting a characteristic of crop plants in a field in a path of an agricultural harvesting machine in a direction of travel, generating, based on the detected characteristic, a height metric representing a height of the crop plants on a particular area of the field, and generating a control signal to control the agricultural harvesting machine based on the height metric and the identified region.
