Human body modeling method, device and electronic equipment
The invention discloses a human body modeling method, a device and electronic equipment. The method comprises the following steps: at least one human body image is acquired; the original contour of the human body in the human body image is extracted; according to the original contour, a body surface contour of the human body is calculated; and according to the body surface contour, a human body three-dimensional model is built. When the human body modeling method, the device and the electronic equipment are executed, as building of the human body three-dimensional model is from a two-dimensional human body image, human body scanning by using a human body scanner is not needed, and the cost overhead when the human body three-dimensional model is built is thus reduced. Besides, the position of a human body target and the clothing of the human body target are not required in the case of human body image acquisition, the operation threshold in the case of building of the human body three-dimensional model is thus reduced, and the process of building the human body three-dimensional model is more convenient.
