Infant sleep monitoring system and method thereof

Abstract

The invention discloses an infant sleep monitoring system and a method thereof, and relates to the computer vision monitoring field. An infrared laser and a digital CCD camera compose a vision sensing system, and the infrared laser is fixed below the CCD camera through a sensor support; an infant sleep bed is provided with a bedding, line laser projected by the infrared laser is projected on the bedding, the line laser is positioned at the lower part of the body of an infant, and the direction of the line laser is vertical to the direction of the body of the infant; the infrared laser projects onto the bedding to form a laser band, and the laser band is acquired by the digital CCD camera to form an image; the pitching angle of the CCD camera can be adjusted on the sensor support to make the narrow and long laser band appear in the center of the visual field of the CCD camera; and the digital image of the narrow and long band captured by the CCD camera is transmitted to a computer through 1394 image acquisition cards by a transmission cable to complete information processing in order to determine whether the infant kicks the bedding or not, that is, vision measuring software is utilized to detect the laser band and determine whether the infant kicks the bedding or not.

Description

technical field [0001] The invention relates to the field of computer vision monitoring, designs an infant sleep monitoring system device based on the principle of infrared structured light vision, and realizes a monitoring method based on the device. Background technique [0002] Computer vision technology is the use of computers to realize human visual functions—the perception, recognition and understanding of three-dimensional scenes in the objective world. It is widely used in the fields of national economy, scientific research and national defense construction. The biggest advantage of visual technology is that it has no contact with the observed object, so it will not cause any damage to the observer or the observed person; in addition, with the help of infrared, microwave, ultrasonic and other visual methods, it can detect the range that cannot be observed by human eyes , thus greatly expanding the limitations of human vision.

AI Technical Summary

Problems solved by technology

[0006] Aiming at the problem of infants and young children pushing on the quilt due to turning over, temporary temperature discomfort and other reasons during the sleep process, the present invention proposes a monitoring device and monitoring method based on infrared structured light vision. In the absence of visible light at night, it can effectively detect whether the bedding of infants and young children is well covered
