Detection device, assistance device and assistance method
A detection device according to an aspect of the present disclosure includes a detection portion that contains a substance that emits fluorescence in a case of being irradiated with light when reacting with a plant hormone.
1. A detection device comprising:
a detection portion that contains a substance that emits fluorescence in a case of being irradiated with light when reacting with a plant hormone.
2. The detection device according to claim 1 , wherein
the substance emits the fluorescence with an intensity that is in proportion to an amount of the reacted plant hormone.
3. The detection device according to claim 1 , further comprising:
a reference portion that contains the substance; and
a shielding portion that is detachable and shields the reference portion from outside air.
4. The detection device according to claim 1 , further comprising:
an identification information portion that holds identification information in a readable manner.
5. The detection device according to claim 1 , wherein
the substance includes at least one of a boron-oxygen compound having a structure represented by General Formula (1) as a receptor that selectively recognizes methyl salicylate, a rare earth compound as a receptor that selectively recognizes methyl salicylate, a zinc compound as a receptor that selectively recognizes methyl salicylate, or a hydrazine derivative as a receptor that selectively recognizes methyl jasmonate
6. An assistance device comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
generate position information of a plant infected with a disease based on a captured image of a detection portion irradiated with light and a position of the detection portion, the detection portion containing a substance that emits fluorescence in a case of being irradiated with the light when reacting with a plant hormone; and
output the generated position information.
7. The assistance device according to claim 6 , wherein
the captured image includes a region of the detection portion and a region of a reference portion that is imaged in a state where a shielding portion that is detachable and shields the reference portion containing the substance from outside air is removed from the reference portion, and
the at least one processor is further configured to generate the position information based on an amount of change in difference between a brightness of the detection portion and a brightness of the reference portion in the captured image.
8. The assistance device according to claim 6 , wherein
the at least one processor is further configured to generate, as the position information, a distribution of a degree of possibility that a plant infected with a disease exists in a place in which the detection portion is disposed.
9. The assistance device according to claim 6 , wherein
the substance includes at least one of a boron-oxygen compound having a structure represented by General Formula (1) as a receptor that selectively recognizes methyl salicylate, a rare earth compound as a receptor that selectively recognizes methyl salicylate, a zinc compound as a receptor that selectively recognizes methyl salicylate, or a hydrazine derivative as a receptor that selectively recognizes methyl jasmonate.
10. An assistance system including the assistance device according to claim 6 , comprising:
a detection device including the detection portion;
an imaging device that captures the captured image; and
a terminal device that receives the position information and displays the position information.
11. An assistance method comprising:
generating position information of a plant infected with a disease based on a captured image of a detection portion irradiated with light and a position of the detection portion, the detection portion containing a substance that emits fluorescence in a case of being irradiated with the light when reacting with a plant hormone; and
outputting the generated position information.
12. The assistance method according to claim 11 , wherein
the captured image includes a region of the detection portion and a region of a reference portion that is imaged in a state where a shielding portion that is detachable and shields the reference portion containing the substance from outside air is removed from the reference portion, and
the assistance method further comprises generating the position information based on an amount of change in difference between a brightness of the detection portion and a brightness of the reference portion in the captured image.
13. The assistance method according to claim 11 , further comprising
generating, as the position information, a distribution of a degree of possibility that a plant infected with a disease exists in a place in which the detection portion is disposed.
14. The assistance method according to claim 11 , wherein
the substance includes at least one of a boron-oxygen compound having a structure represented by General Formula (1) as a receptor that selectively recognizes methyl salicylate, a rare earth compound as a receptor that selectively recognizes methyl salicylate, a zinc compound as a receptor that selectively recognizes methyl salicylate, or a hydrazine derivative as a receptor that selectively recognizes methyl jasmonate.
15. The assistance method according to claim 11 , further comprising:
capturing, using an imaging device, the captured image of the detection portion included in a detection device;
receiving, using a terminal device, the position information; and
displaying, using the terminal device, the position information.
