Scouting systems
Embodiments include a ground scout having an ability to identify the location of rows of crops and the end of the rows so that it can navigate, but in other embodiments, the ground scout can also rely more on an aerial drone to navigate, to act as a communication relay system, and so on. A buddy system including a ground scout and an air scout (e.g. drone) communicate their findings with each other.
1. An agricultural scouting system comprising:
a ground vehicle having a perception sensor, a motion sensor and a computer, wherein the ground vehicle is autonomous;
wherein the computer receives motion information from the motion sensor as the ground vehicle moves;
wherein the computer having instructions to ascertain from the perception sensor a position of the ground vehicle in a coordinate system of the ground vehicle, forming an occupancy grid based on a strength associated with cells of the occupancy grid; and the computer to transform the coordinate system to a second coordinate system;
wherein the second coordinate system includes a global motion of the ground vehicle and surrounding objects to generate candidate crop lanes, and wherein generating the candidate crop lanes includes identifying and classifying one or more non-crop plant in-lier objects arranged within the candidate crop lanes; a row model, wherein the candidate crop lanes are compared to the row model; and a vehicle path that the ground vehicle drives, wherein the vehicle path is based on a best scorer among the candidate crop lanes; and
wherein the computer is configured to generate an output signal received by an external vehicle to cause the external vehicle to perform a task when the one or more non-crop plant in-lier objects are identified within the candidate crop lanes.
2. The agricultural scouting system of claim 1 , wherein the best scorer is determined from a number of perception sensor readings that fall in a region where plants are expected.
3. The agricultural scouting system of claim 1 , wherein the row model is parameterized by at least one of a row width, a row length and a lane heading direction of a farm field.
4. The agricultural scouting system of claim 1 , wherein the vehicle path is derived without use of a GPS.
5. The agricultural scouting system of claim 1 , wherein the ground vehicle is sized approximately 15 to 20 inches in width, and wherein a height of the ground vehicle is less than a height of a mature crop canopy that includes corn.
6. The agricultural scouting system of claim 1 , wherein the second coordinate system comprises a farm field coordinates or an Earth coordinates.
7. The agricultural scouting system of claim 1 , wherein the ground vehicle travels with and is in communication with a tractor or a sprayer vehicle to monitor spraying or to guide spraying.
8. The agricultural scouting system of claim 1 , wherein the ground vehicle is in communication with an aerial drone to share agricultural monitoring tasks.
9. The agricultural scouting system of claim 8 , wherein the ground vehicle and the aerial drone are docked together on an agricultural vehicle that provides a power source to the ground vehicle and to the aerial drone.
10. The agricultural scouting system of claim 8 , wherein the ground vehicle receives GPS information from the aerial drone.
