Abstract: Fatigue driving monitoring, reminding and early-warning method and system based on computer vision are provided. The system includes: a fatigue real-time monitoring system for identifying fatigue characteristic postures of a driver and obtaining a fatigue level according to frequencies of the fatigue characteristic postures and a driving time; a fatigue automatic reminding system for receiving the fatigue level, obtaining a vehicle real-time position information and providing the driver with a corresponding grade of reminder according to the fatigue level; and a fatigue information early-warning system for receiving the fatigue level and the vehicle real-time position information to obtain a fatigue safety index, so that a cloud map of fatigue road conditions is obtained according to the fatigue safety index and shared with traffic management departments and drivers for early-warning. It reduces the situation of fatigue driving on freeway and the hazard of traffic safety accidents caused by fatigue driving.

Abstract: A construction site safety monitoring system based on computer vision is provided. It includes a data acquisition system for collecting video information of personnel and operation platforms on construction site in real time; an information processing system for detecting and distinguishing the personnel and the operation platforms in the video information, intercepting personnel feature images and video of tilted operation platform whose personnel facial temperature and inclination angles after calculation are greater than or equal to preset values as a personnel safety incident and a platform safety incident respectively; and a terminal reminder system for receiving information of at least one the personnel safety incident and the platform safety incidents and providing a reminder.

Abstract: Sunshading louver control system and method based on gesture recognition are provided. Indoor images are collected in real time. Based on the indoor images, an action region of gesture motion is positioned and feature extraction is performed thereon to obtain hand motion parameters. The hand motion parameters are analyzed to obtain gesture information. The gesture information is compared with preset gesture information. When the preset gesture information contains the gesture information, corresponding adjustment is performed on a sunshading louver according to a preset operation logic corresponding to the gesture information. When the preset gesture information does not contain the gesture information, the gesture information is determined to be invalid.

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.

Abstract: An air supply device is provided, which includes a housing with a cavity being formed therein. The air supply device further includes a partition plate, dividing the cavity of the housing into an upper cavity and a lower cavity; a flow equalizing plate, being vertically arranged in the upper cavity to divide the upper cavity into an air inlet cavity and a static pressure cavity, where a first air inlet that is communicated with the air inlet cavity being formed in the housing; an adjustable baffle plate, having a vertical height less than a vertical height of the lower cavity. The adjustable baffle plate divides the lower cavity into an induction cavity and a heat exchange cavity. The adjustable baffle plate and a top of the lower cavity form a first induced air opening. A heat exchanger is arranged in the heat exchange cavity.
