The invention discloses a three-dimensional virtual
human head image generation method, and a method and a device of
human head image motion tracking, and belongs to the field of
image processing. The three-dimensional virtual
human head image generation method comprises collecting a human face picture, obtaining feature points on the human face picture, wherein the feature points are used for showing a
left eyebrow, a
right eyebrow, a
left eye, a right eye, a
nose, the edge contour of a human face and a
forehead portion of the human face; obtaining a personalized three-dimensional human
face model according to the obtained feature points and a preset standard human
face model; and carrying out
texture mapping to the personalized three-dimensional human
face model, and generating a three-dimensional virtual human head image. Due to the facts that the feature points which are used for characterizing feature information of the human face on a single human face picture are obtained, and are applied in the three-dimensional human face model, and the personalized three-dimensional human face model which includes the
forehead portion and is good in third dimension is generated, the three-dimensional virtual human head
image generation method, and the method and the device of the human head
image motion tracking have the advantages of being in no need of manual marking of the feature points, greatly reducing manual
processing amount, being applicable to modeling occasions which require for simpleness and speediness, and being capable of enabling the third dimension of the generated three-dimensional human head image to be greatly improved and to be high in accuracy due to the fact that the feature points include feature points of the
forehead portion of the human face.
