Provided are an apparatus and a method for manipulating depth of a stereoscopic image that enable a user to manipulate depth of a stereoscopic image easily and intuitively. The apparatus may include: a histogram analyzing unit acquiring a depth distribution chart by performing histogram analysis of a disparity map corresponding to an input image; a Gaussian mixture model (GMM) fitting unit acquiring multiple depth layers by performing GMM fitting of the depth distribution chart; a disparity adjusting unit adjusting at least one of a position and a volume of at least one of the multiple depth layers and calculating a disparity mapping function on which a result of the adjustment is reflected in response to a user request; and a disparity map recalculating unit calculating a new disparity map by optimizing the disparity mapping function.

Apparatus and method for depth manipulation of stereoscopic 3D image

Disclosed herein are a stereoscopic image generation method of background terrain scenes, a system using the same, and a recording medium for the same. The stereoscopic image generation method of background terrain scenes includes an initial mesh creation step of creating an initial mesh using terrain geometry based on image sequences, a geometry error correction step of generating a projection map, detecting error regions of the initial mesh using the generated projection map, generating a vector map of the detected error regions, and generating a corrected mesh, error of which is corrected, and a stereo conversion step of generating a stereoscopic image using the corrected mesh. Since the stereoscopic image is generated based on the mesh, the mesh fits the terrain shape even though the geometry is complex. Further, time coherence can be enforced, the mesh can be edited easily, and new elements can be unseamingly composed into the terrain. Thus, it is possible to prevent a viewer who views the stereoscopic image from becoming tired.
