Variable rate sprayer system and method of variably applying agrochemicals

A method of variably applying an agrochemical, the method comprising:

• capturing an image;
• processing the image to determine image features by using only a subset of luminance, hue, saturation and intensity image features;
• and
• controlling a variable rate spray nozzle based on the image features to thereby deliver an appropriate amount of the agrochemical.

A non-transitory computer-readable medium comprising instructions in code which when executed by a processor of a computing device cause the computing device to:

• send a signal to digital camera to cause the digital camera to capture an image;
• receive image data from the digital camera;
• process the image to determine image features by using only a subset of luminance, hue, saturation and intensity image features;
• and
• control an agricultural device based on the image features.

A mobile variable rate sprayer system for applying an agrochemical, the system comprising:

• a vehicle for transporting the agrochemical;
• at least one digital camera mounted to the vehicle for capturing an image;
• a processor for processing the image into RGB components and to determine a G ratio by computing a ratio of G to the sum of R, G and B;
• at least one controller for receiving signals from the processor;
• and
• at least one variable rate sprayer mounted on the vehicle, wherein each spray nozzle of the sprayer is controlled by the controller based on the G ratio.
