Step 1, take out a frame from planar video, be referred to as former figure, the length of supposing this frame is X, and wide is Y; Specify the depth value of X * Y pixel on the described former figure, form an image that is called depth map;
Step 2, adopt the rendering intent based on depth map, described former figure and depth map are generated be applicable to that specification is the image at N virtual visual angle of N view three-dimensional display, each image size is X * Y, is called the A image series;
Step 3, generation specification are the 3D rendering of N view, are called the B image series;
Step 4, for the B image series, the mask value of specifying its each pixel is P or Q, P ≠ Q: the pixel value of the point that described 3D model object is covered is labeled as P, and other are labeled as Q; Forming size is the mask image of X * Y, is called the C image series;
Step 5, utilize N road C image series as mask with the B image series A image series that is added to: promptly pixel value is that the point of P is got the pixel value of corresponding points on the B image series on the mask image, otherwise gets the pixel value of corresponding points on the A image series; Obtain N road composograph, be called the D image series, as a frame of 3D video;
Step 6, produce each frame of 3D video, form every frame and have the frame series of N road view, be called the E series of frames with step 1 to the method for step 5;
Step 7, the E series of frames synthesized the 3D video that is applicable to N view three-dimensional display specification.
Described B image series can be a frame of one section specification 3D video that is the N view.
Described B image series can be the image that is generated by following method: adopt computer 3D cartoon technique, make 3D model object; In virtual 3D scene, take pictures with N virtual video camera of coupling N view three-dimensional display parameter, generate the image at N virtual visual angle, each image size is X * Y.
Described B image series can be to be the 3D rendering of N view by the specification that plane picture changes into.
N is the positive integer more than or equal to 2.
Advantage of the present invention is: change at planar video on the basis of 3D video, the 3D video that has superposeed and adopted computer 3D animation to generate makes final synthetic 3D video have good 3D effect.
