The invention relates to a human eye tracking method and device for a naked-eye 3D device. A human eye tracking method for a naked-eye 3D device, comprising acquiring a user's face image, obtaining the coordinates of the midpoint of the eyes in the face image; determining that the coordinates of the midpoint of the eyes fall outside the preset target area in the image, and setting the target area Between the preset 3D left view area and 3D right view area in the image; rotate the naked-eye 3D device so that the coordinates of the midpoint of both eyes fall into the target area. To solve the problem that it is difficult for users to find and keep their eyes in the best viewing angle range when using naked-eye 3D devices, so that users do not need to deliberately find or maintain viewing angles within the range of visual distance, and get rid of dizziness and serious crosstalk experience the ideal 3D effect easily.

The invention provides a method for converting a two-dimensional video into a three-dimensional video automatically. The method comprises the following steps of: firstly, performing Gauss modeling on the background of a static scene with a mobile object to reestablish a static background and segment an approximate foreground region out; secondly, performing geometrical classification on each pixel of a background image by using monocular geometrical information and a classifying studying algorithm and obtaining a depth map according to a classification result; segmenting the image of the foreground region by using a mean shift algorithm; performing edge detection, edge connection and endpoint elimination on the image to obtain a precise foreground region; and fusing the precise foregroundregion with the depth map of the background to obtain the depth map of each frame.
