Abstract

The invention provides a three-dimensional head model construction method, device and system and a storage medium. The three-dimensional head model construction method comprises the following steps: acquiring at least one face image of a user; acquiring facial contour feature points of the user according to the at least one facial image; determining an initial three-dimensional head model of the user according to the facial contour feature points; acquiring facial local feature points of the user according to the at least one facial image; and according to the facial local feature points, correcting the local structure of the initial three-dimensional head model to obtain a personalized three-dimensional head model conforming to the facial features of the user. According to the embodiment of the invention, the three-dimensional head model with a complete structure can be obtained, the matching degree with the head of a real person is higher, more accurate personalized processing can be realized, and the authenticity of the model is improved; and meanwhile, the calculation amount is effectively reduced, the degree of dependence on the server is reduced, and the transmission speed is increased.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular, the present application relates to a construction method, device, system and storage medium of a three-dimensional head model. Background technique [0002] A head model construction method currently available on the market does not match the head model with the actual human head, and usually only models the part rather than the whole, so the model established in this way cannot show the shape of the human head. The overall features have a low degree of matching with the real human body; in addition, the current methods usually construct the points and faces of the model based on the points of the actual human head when modeling. In order to improve the authenticity, the number of faces of the model needs to be increased , and increasing the number of faces needs to involve more head points, due to the large amount of overall data, resulting in a large amount...
