Abstract: Methods, systems, apparatus, and articles of manufacture for camera calibration are disclosed. An example apparatus includes memory, instructions, and programmable circuitry to execute the instructions to detect, based on video frames captured by a camera positioned on a vehicle, a ground plane of the vehicle, determine, based on the ground plane, a first position parameter of the camera with respect to a coordinate system of the vehicle, track a plurality of features between ones of the video frames, and determine, based on the plurality of features, a second position parameter of the camera with respect to the coordinate system of the vehicle, the first position parameter different from the second position parameter.

Abstract: An agricultural material application machine includes a material reservoir that holds a material to be applied to a field, an orifice defining an opening through which material is to pass to be applied to the field, an optical sensor that captures an image of a portion of the field, and a n image processor that processes the image and identifies a target in the image. The agricultural material application machine further includes a confidence level generator that generates a confidence level based on confidence data and a controller that generates a control signal to control the agricultural material application machine based on the confidence level.

Abstract: An agricultural applicator, that applies material to an agricultural field, includes an on-board, real-time image sensor that senses targets for the material to be applied. A controller controls applicators, such as nozzles or other applicators, to apply the material to the sensed targets.
