Abstract: There is provided a plant stress detection apparatus including a first light source that radiates a reference beam of a first wavelength that has a characteristic of tending not to be absorbed in water toward a plant by optical scanning, a second light source that radiates a measuring beam of a second wavelength that has a characteristic of tending to be absorbed in water toward the plant by optical scanning, and a detector that detects presence or absence of water or undulation of the plant based on reflection light of the reference beam that is reflected at an irradiation position of the plant that has a first irradiation area and reflection light of the measuring beam that is reflected at an irradiation position of the plant that has a second irradiation area that is different from the first irradiation area.

Abstract: The present disclosure accurately detects the position of a shelf label disposed on a display shelf. A shelf label detection device may be provided with a shelf label position correction unit and a shelf label position identification unit. The shelf label position correction unit corrects a manual shelf label position set including a shelf label position that has been set in advance for a reference camera image, using an automatic shelf label position set which includes a shelf label position detected from a monitoring camera image using image recognition, thereby generating a corrected shelf label position set. The shelf label position identification unit uses the corrected shelf label position set to identify the shelf label position in the monitoring camera image.

Abstract: A substance detection sensor includes a first light source, a second light source, and a substance detector. The first light source irradiates a detection area including a plurality of target areas with reference light having a first wavelength through surface irradiation using optical scanning. The second light source irradiates the detection area with first measuring light having a second wavelength different from the first wavelength through the surface irradiation using the optical scanning. The substance detector detects a specific substance in the detection area based on reflection light of the reference light from the first light source and reflection light of the first measuring light from the second light source.

Abstract: A shelf monitoring device may be provided with a detector, a setter, a monitoring section, and an output section. The detector detects shelf labels attached to a display shelve to correspond to articles to be displayed on the display shelves, with video recognition of video data that includes the display shelves. Based on the position of the detected shelf label, the setter sets a monitoring area in which articles to be displayed on the display shelves in video data. The monitoring section monitors the shelving condition of the articles on the display shelves based on a change in video in response to the presence or absence of the article in the monitoring area. The output unit outputs the monitoring results according to the monitoring unit.
