Abstract: A control system and a control method of refrigeration in a closed space based on computer vision are provided. An image of a food, temperature and humidity information in the closed space are collected, and a type of the food is identified according to the image. The image is processed through Euler video amplification when food is not packaged to obtain surface color distribution information of the food, a state of the food is determined according to the surface color distribution information and a historical learning result, and a state prompt corresponding to the state of the food is provided to a user. Temperature and humidity in the closed space are regulated according to the state of the food. The state of the food is determined according to storage time and a known quality guarantee period when the food is packaged, and another state prompt is provided to the user.

Abstract: A control system and a control method for individual thermal comfort based on computer visual monitoring are provided. The control system may include a data acquisition device, an information processing device, an intelligent voice inquiry device, a terminal control device including a terminal controller connected to an external equipment and a biological real-time device connected to the data acquisition device and a human thermal sensation predictor. The data acquisition device includes a semi-contact measurement instrument and a contact-less measurement instrument. The contact-less measurement instrument includes an infrared sensor and a camera built with a skeletal node recognizer and an Euler video amplifier. The information processing device may include a memory, the human thermal sensation predictor for obtaining the predicted thermal sensation value and a comparator connected to the intelligent voice inquiry device. It solves the problem that the prior art cannot meet the thermal comfort.

Abstract: Temperature-controlled mattress control system and method based on sleep posture detection are provided. The control system includes an information collecting unit, an information processor and an output instruction unit. The information collecting unit is used to collect a temperature parameter of a human body during sleeping, video information, and a temperature parameter of a temperature-controlled mattress. The information processing unit receives information collected by the information collecting unit, calculates a sleep posture value K, a thermal sensation value P and a facial skin thermal value Q to obtain a final estimated thermal sensation, and determines setting temperature variation of the temperature-controlled mattress based on the temperature parameter of the temperature-controlled mattress.
