Abstract
A system is provided to monitor targeted pest populations, disease, presence of transgenic and non-transgenic plants, or targeted pest population in a transgenic crop using remote imagery to discern differences in crops along with pest infestation in all crop varieties. The system relies on the fact that plant leaves are known to change color based on stress, herbivory, and other environmental factors. The system provides a special camera that can see reflected light energy across the visible and near infrared (about 400-1000 nm) to identify these effects.
Claims20
A method of determining a characteristic of a plant said characteristic selected from the group consisting of growth stage disease state, infestation and effects from soil deficiencies or dehydration, comprising:
- collecting reflected solar energy from a plant surface of unidentified genetic composition;
- forming the collected solar energy into a multiband image, and;
- analyzing the multiband image.
A method of determining a characteristic of a plant wherein said characteristic is selected from the group consisting of genetic composition, growth state, disease state, infestation and effects from soil deficiencies or dehydration, comprising:
- collecting reflected solar energy from a surface of a plant of unidentified genetic composition;
- forming the collected solar energy into a multiband image, and;
- analyzing the multiband image comprising at least one of comparing a first portion of the multiband image with a second portion of the multiband image, reducing at least a portion of the multiband image to a proportionate value referring to the comparison of datasets derived from one or more images, and comparing the proportionate value to a reference value, and comparing at least a portion of the multiband image with a reference multiband image.
A method of determining whether a plant of unidentified genetic composition is a transgenic plant or a non-transgenic plant for plants of, comprising:
- collecting reflected solar energy from a surface of a plant of unidentified genetic composition;
- forming the collected solar energy into a multiband image, and;
- analyzing the multiband image.
