Abstract

A method and apparatus for managing undesired material in an area. A sensor system monitors the area for the undesired material. A number of operations is performed on the area using a vehicle system. The vehicle system comprises a vehicle and a structure connected to the vehicle. A computer system receives data for the area from the sensor system. The computer system identifies a presence of the undesired material along a number of paths in the area using the data to form an identification. The computer system initiates removal of the undesired material based on the identification.

First claim

What is claimed is:

1. A method for managing undesired material in an area, the method comprising:
monitoring the area for the undesired material using a sensor system, wherein a number of operations is performed on the area using a vehicle system, wherein the vehicle system comprises a vehicle and a structure connected to the vehicle;
receiving, by a computer system, data for the area from the sensor system;
identifying, by the computer system, a presence of the undesired material along a number of paths in the area using the data to form an identification, wherein the number of paths are concurrently formed by the structure; and
initiating removal, by the computer system, of the undesired material based on the identification.

2. The method of claim 1 , wherein the initiating the removal of the undesired material based on the identification comprises:
generating an alert indicating that the undesired material is to be removed.

3. The method of claim 2 , wherein the initiating the removal of the undesired material is performed responsive to generating the alert.

4. The method of claim 1 , wherein the initiating the removal of the undesired material based on the identification comprises:
sending a signal to at least one removal member attached to the structure to remove the undesired material.

5. The method of claim 4 , wherein the identifying the presence of the undesired material along the number of paths in the area using the data to form the identification comprises:
identifying the presence of the undesired material along the number paths in the area using the data to form the identification, wherein the identification includes a number of positions for the undesired material along the number of paths in the area.

6. The method of claim 5 , wherein the signal includes the number of positions for the undesired material along the number of paths in the area, and further comprising:
locating the at least one removal member along the structure based on the number of positions for the undesired material along the number of paths in the area.

7. The method of claim 5 further comprising:
identifying the number of positions for the undesired material along the number of paths in the area using the data and a number of locations for a number of objects associated with the structure.

8. The method of claim 1 , wherein the sensor system comprises an imaging system configured to generate imaging data.

9. The method of claim 8 , wherein the imaging data comprises images and wherein the identifying the presence of the undesired material along the number of paths in the area using the data to form the identification comprises:
identifying a number of changes in a number of features between a set of images in the images; and
identifying the presence of the undesired material along the number of paths in the area when a change in the number of changes in the number of features between a first image in the set of images and a second image in the set of images is greater than a selected threshold.

10. The method of claim 8 , wherein the data comprises at least one of the imaging data, structured light data, and laser data; and wherein the imaging data is generated by the imaging system in the sensor system, the structured light data is generated by a structured light sensor system, and the laser data is generated by a laser system in the sensor system.

11. The method of claim 10 , wherein the identifying the presence of the undesired material along the number of paths in the area using the data to form the identification comprises:
selecting at least one of the imaging data, the structured light data, and the laser data using a policy to form selected data; and
identifying the presence of the undesired material along the number of paths in the area using the selected data to form the identification, wherein the identification includes a number of positions for the undesired material along the number of paths in the area.

12. The method of claim 10 , wherein the identifying the presence of the undesired material along the number of paths in the area using the data to form the identification comprises:
applying weighting factors to the at least one of the imaging data, the structured light data, and the laser data to form weighted data; and
identifying the presence of the undesired material along the number of paths in the area using the weighted data to form the identification, wherein the identification includes a number of positions for the undesired material along the number of paths in the area.

13. The method of claim 10 further comprising:
directing a number of beams of light across the number of paths in the area; and
receiving a number of responses to the number of beams of light.

14. The method of claim 13 , wherein the identifying the presence of the undesired material along the number of paths in the area using the data to form the identification comprises:
identifying a change in a desired pattern for the number of responses, wherein the change indicates the presence of the undesired material along the number of paths in the area.

15. The method of claim 1 , further comprising:
monitoring movement of the structure relative to the vehicle using the sensor system.

16. The method of claim 15 , further comprising:
identifying a number of distances from the sensor system associated with the vehicle to a number of objects associated with the structure;
identifying an orientation of the structure relative to the vehicle using the number of distances from the sensor system associated with the vehicle to the number of objects;
determining whether the orientation of the structure meets a number of criteria; and
initiating an operation for the vehicle system in response to an absence of a determination that the orientation meets the number of criteria.

17. An apparatus comprising:
a sensor system configured to monitor an area for undesired material, wherein a number of operations is performed on the area using a vehicle system, wherein the vehicle system comprises a vehicle and a structure connected to the vehicle, and wherein the number of operations includes at least one of tilling, sowing, plowing, planting and seeding;
a computer system configured to receive data for the area from the sensor system, identify a presence of the undesired material along a number of paths in the area using the data to form an identification, and initiate removal of the undesired material based on the identification, wherein the number of paths are concurrently formed by the structure when performing the number of operations.

18. The apparatus of claim 17 further comprising:
at least one removal member connected to the structure and configured to remove the undesired material.

19. The apparatus of claim 18 , wherein in being configured to identify the presence of the undesired material along the number of paths in the area using the data to form the identification, the computer system is configured to identify the presence of the undesired material along the number paths in the area using the data to form the identification, wherein the identification includes a number of positions for the undesired material along the number of paths in the area.

20. The apparatus of claim 19 , wherein the computer system is further configured to send a signal to the at least one removal member to remove the undesired material, wherein the signal includes the number of positions for the undesired material along the number of
