Infant height automatic measuring method, system and device and storage medium

The invention discloses an automatic infant height measuring method, system and device and a storage medium. The method comprises the steps that image information including an infant and camera parameters for collecting the image information are obtained; detecting skeleton articulation points of the infant according to the color image, judging whether a detection result meets a preset requirement, and if yes, obtaining key skeleton articulation points according to the detection result; acquiring the pixel coordinates of the key skeleton joint points, and acquiring the three-dimensional coordinates of the key skeleton joint points in the first coordinate system according to the pixel coordinates, the camera parameters and the depth image; the first coordinate system is a coordinate system taking the optical center of the camera as an original point; calculating the distance between the nodes according to the three-dimensional coordinates of the key skeleton joint points, and obtaining the height of the baby a
