Abstract
Presented herein are systems and methods for automatically determining liquid coverage on plant surfaces. More particularly, in certain embodiments, presented herein is a system for receiving an image depicting one or more plant surfaces, automatically identifying the plant surfaces in the image and distinguishing portions covered by liquid, and automatically determining a liquid coverage value. In some embodiments, the system determines changes to liquid spraying parameters to achieve desired liquid coverage values. In some embodiments, the system uses two cameras to cooperatively conduct background removal in images and determination of liquid coverage.
Claims39
A system for automatically quantifying liquid coverage on plant surfaces, the system comprising:
- a processor of a computing device;
- and
- a memory having instructions stored thereon, wherein the instructions, when executed by the processor, cause the processor to:
- receive an image comprising a region of interest corresponding to one or more plant surfaces;
- automatically identify one or more portions of the region of interest corresponding to liquid;
- and
- use (i) one or more pre-spray images corresponding to a field of view comprising the one or more plant surfaces prior to spraying with a liquid and (ii) one or more post-spray images corresponding to the field of view comprising the one or more plant surfaces after spraying with the liquid
- to automatically identify a liquid coverage value for the plant surfaces by:
- (i) removing background pixels in the one or more pre-spray images so that leaves remain;
- (ii) removing background pixels in the one or more post-spray images so that leaves remain;
- and
- (iii) calculating the liquid coverage value based on pixels corresponding to leaves and sprayed liquid in the one or more pre-spray images and the one or more post-spray images.
A method for automatically quantifying liquid coverage on plant surfaces, the method comprising:
- receiving, by a processor of a computing device, an image comprising a region of interest corresponding to one or more plant surfaces;
- automatically identifying, by the processor, one or more portions of the region of interest corresponding to liquid;
- and
- using (i) one or more pre-spray images corresponding to a field of view comprising the one or more plant surfaces prior to spraying with a liquid and (ii) one or more post-spray images corresponding to the field of view comprising the one or more plant surfaces after spraying with the liquid
- to automatically identify a liquid coverage value for the plant surfaces by:
- (i) removing background pixels in the one or more pre-spray images so that leaves remain;
- (ii) removing background pixels in the one or more post-spray images so that leaves remain;
- and
- (iii) calculating the liquid coverage value based on pixels corresponding to leaves and sprayed liquid in the one or more pre-spray images and the one or more post-spray images.
