Abstract: A lighting system includes a plurality of lighting devices and a control device. The plurality of lighting devices are installed in a facility. The control device controls the plurality of lighting devices. The control device controls lighting light projected by at least one lighting device, belonging to the plurality of lighting devices, into colored lighting light, of which a color is different from a color white, to give, upon acquiring information about an event in question, a sign depending on the event in question.

Abstract: A weight estimation system includes: an image capturer that captures an image of an inside of a poultry house; a calculator that calculates a flocking behavior feature quantity of chickens in the poultry house by performing image processing on the image captured by the image capturer; and an estimator that estimates a weight for each chicken in the poultry house, based on the flocking behavior feature quantity calculated.

Abstract: A livestock house monitoring method includes: capturing a moving image of an inside of a poultry house; converting a plurality of images included in the moving image captured into black-and-white images; and generating an image for monitoring purposes showing a distribution of chickens inside the poultry house by performing statistical processing on the plurality of images converted into the black-and-white images. The poultry house is an example of a livestock house, and chickens are an example of livestock.

Abstract: A poultry raising system (10) includes: an imager (21) that captures an image of an inside of a poultry house; a monitor (32a) that monitors a feature quantity of chickens in the poultry house, the feature quantity being obtained by performing image processing on the image captured by the imager (21); and a calculator (32b) that calculates, based on information indicating a state of growth of the chickens in the poultry house, a threshold used for providing a notification about the chickens in the poultry house, the notification being provided based on the feature quantity.

Abstract: A water supply apparatus is arranged inside a house body and includes a watering apparatus that performs watering to a cluster of plants from above. The watering apparatus supplies water to the plants and controls an ambient temperature of the plants due to heat transfer utilizing vaporization heat by watering. A control apparatus acquires an environment information including the ambient temperature of the plants from an environment sensor, and performs the watering by driving the water supply apparatus in a watering period determined according to the environment information, and prohibits the watering by the water supply apparatus in an idle period that is set after the watering period so as to obtain a temperature and a humidity appropriate for growth of the plants.

Abstract: An installation evaluation apparatus 10 for a greenhouse includes an input device 11, an insolation evaluation unit 12, and a presentation device 13. The input device 11 is configured to receive input of position information relating to a planned location for installing the greenhouse. The insolation evaluation unit 12 is configured to determine variation, according to the date and time, in an insolation amount in the planned location by performing a computer simulation using the position information input into the input device 11. The presentation device 13 is configured to visualize and present the variation in the insolation amount according to the date and time, determined by the insolation evaluation unit 12.
