Document Type and Number:
WIPO Patent Application WO/2020/218323
Kind Code:
A1
Abstract:
Provided are a plant imaging device and a plant imaging method that are capable of distinguishing an imaging subject plant 80 positioned inside an area having a prescribed distance L from an imaging means 1 from a non-imaging subject plant 90 at a position more than the prescribed distance L from the imaging means 1, and capturing an image of same, as a result of being characterized by: using, as a target imaging area 33, an area in which a first irradiation area 31 irradiated from one illumination means 3 and a second irradiation area 32 irradiated from another illumination means 3 overlap; using, as outside the target imaging area 33, an area in which the first irradiation area 31 and the second irradiation area 32 do not overlap; generating a light-level difference between the target imaging area 33 and outside the target imaging area 33; using the light-level difference to distinguish the imaging subject plant 80 positioned inside an area at a prescribed distance L from the imaging means 1, from a non-imaging subject plant 90 that is at a position exceeding the prescribed distance L from the imaging means 1; and capturing an image of the imaging subject plant 80.
