Method, system, and medium having stored thereon instructions that cause a processor to execute a method for obtaining image information of an organism comprising a set of optical data

A device comprising:

• at least one processor configured to:
• receive a subject image including agricultural produce, the subject image including red (R) image data and near-infrared ray (NIR) image data;
• specify a target region in the subject image corresponding to the agricultural produce
• based on:
• (a) an index calculated from reflectance of R light and NIR light derived from the R image data and the NIR image data, and
• (b) a pattern of the target region extracted from at least the R image data;
• and
• estimate a growth situation of the agricultural produce based on the target region in the subject image corresponding to the agricultural produce, and
• wherein the at least one image sensor is installed at an angle to capture, in the subject image, R light intensity and NIR light intensity of incident light that is not reflected from the agricultural produce and light intensity of light that is reflected from the agricultural produce and wherein the at least one processor is further configured to calculate the index based on measured R light intensity and NIR light intensity of the incident light that is not reflected from the agricultural produce and the light intensity of light that is reflected from the agricultural produce in the target region.

A method of producing agricultural products, comprising:

• growing agricultural produce,
• capturing, by at least one image sensor, a subject image including the agricultural produce, the subject image including red (R) image data and near-infrared ray (NIR) image data, wherein the at least one image sensor is installed at an angle to capture, in the subject image, R light intensity and NIR light intensity of incident light that is not reflected from the agricultural produce and light intensity of light that is reflected from the agricultural produce;
• specifying, by at least one processor, a target region in the subject image corresponding to the agricultural produce;
• calculating a reflectance of R light and NIR light based on (i) the R image data and the NIR image data of the agricultural produce, and (ii) R light intensity and NIR light intensity of incident light that is not reflected from the agricultural produce,
• monitoring a growth situation of the agricultural produce based on the reflectance in the target region in the subject image corresponding to the agricultural produce;
• and
• harvesting the agricultural produce at a proper harvest timing.
