The invention discloses a nose adjusting method based on a human face surface three-dimensional grid and application thereof. The objective of the invention is to realize the overall shape change of the face surface and ensure the continuity of the changed face surface by continuously adjusting the geometric control point parameters of the nose in the three-dimensional grid of the face surface. The embodiment of the invention relates to a nose adjusting method and device based on a human face surface three-dimensional grid. The method comprises the following steps: firstly, positioning controlpoints of a nose, sequentially determining control points of a nose height line, a nose profile, a nose side line and a nose bottom line, and secondly, respectively adjusting the nose height, the nose wings and the nose bottom. According to the embodiment of the invention, the nose can be adjusted at any face angle.
