Digital human body construction method and device, storage medium and program product

The invention provides a digital human body construction method and device, a computer readable storage medium, a program product and a digital human body system. The construction method comprises the following steps: acquiring a real-time dynamic image of a to-be-detected human body; extracting the dynamic image frame by frame to generate a plurality of static images; identifying a plurality of body key points of the to-be-detected human body in the plurality of static images, and obtaining coordinates of the plurality of body key points; generating a 3D model of the at least one internal organ; superposing the 3D model of the at least one internal organ on the at least one static image based on the coordinates of the plurality of body key points and the 3D model of the at least one internal organ to form at least one superposed image; and synthesizing the at least one superimposed image and other static images except the at least one static image in the plurality of static images frame by frame to form a synthesized dynamic image.
