Abstract

Various embodiments of an apparatus, methods, systems and computer program products described herein are directed to an agricultural observation and treatment system and method of operation. The agricultural treatment system may determine a first real-world geo-spatial location of the treatment system. The system can receive captured images depicting real-world agricultural objects of a geographic scene. The system can associate captured images with the determined geo-spatial location of the treatment system. The treatment system can identify, from a group of mapped and indexed images, images having a second real-word geo-spatial location that is proximate with the first real-world geo-spatial location. The treatment system can compare at least a portion of the identified images with at least a portion of the captured images. The treatment system can determine a target object and emit a fluid projectile at the target object using a treatment device.

First claim

What is claimed is:

1 . A fluid spraying apparatus, comprising:
a first group of one or more image sensors for obtaining digital imagery; one or more illumination devices; a treatment unit configured to emit a projectile fluid; one or more tanks wherein the tanks provide a container for a fluid; an electronically controlled pump fluidly connected to the one or more tanks and the treatment unit; a power supply, the power supply electrically coupled to the one or more image sensors, coupled to the one or more illumination devices, and coupled to the electronically controlled pump; and one or more processors, memory and a non-transitory computer readable storage medium comprising hardware, the one or more processors configured to control operation of the first group of one or more image sensors, control operation of the one or more illumination devices, and control actuation of the electronically controlled pump for spraying the fluid via the treatment unit.

2 . The fluid spraying apparatus of claim 1 , further comprising:
a navigation subsystem for determining geo-spatial locations of the fluid spraying apparatus, the navigation sub-system interconnected to the one or more processors.

3 . The fluid spraying apparatus of claim 1 , further comprising:
a second group of one or more image sensors for obtaining digital imagery of fluid being dispensed onto a target object, wherein the one or more processors are configured to control operation of the second group of one or more image sensors.

4 . The fluid spraying apparatus of claim 1 , wherein the first group of one or more image sensors comprise stereo cameras and the one or more illumination devices comprise light emitting diodes, the stereo cameras and the one or more illumination devices capable of being synchronized at an operating frequency of 240 Hz.

5 . The fluid spraying apparatus of claim 1 , wherein the first group of one or more cameras, the one or more more illumination devices, and the spraying devices form an integrated perch assembly.

6 . The fluid spraying apparatus of claim 5 , wherein the apparatus includes two or more of the integrated perch assemblies.

7 . The fluid spraying apparatus of claim 5 , wherein the integrated perch assembly comprises:
a first bank of one or more illumination devices mounted to a subframe; a second bank of one or more illumination devices mounted to the subframe; a camera bank of one or more of the first group of image sensors disposed between the first and second bank of illumination devices, the camera bank having a right end and a left end; and a first treatment unit disposed at the left end of the camera bank, and a second treatment unit disposed at the right end of the camera bank.

8 . The fluid spraying apparatus of claim 1 , further comprising:
at least one laser source to emit a laser light towards an object, wherein the one or more processors are configured to control operation of the laser light source.

9 . The fluid spraying apparatus of claim 1 , wherein the treatment unit comprises a spraying device with a spraying nozzle, the spraying device mounted to a gimble for adjustment to an orientation of the spraying nozzle.

10 . The fluid spraying apparatus of claim 1 , wherein the fluid spraying apparatus is mounted to a vehicle.
