Methods, systems, and computer-readable storage media for identifying a rough depth map in a scene and for determining a stereo-base distance for three-dimensional (3D) content creation

摘要

Methods, systems, and computer program products for determining a depth map in a scene are disclosed herein. According to one aspect, a method includes collecting focus statistical information for a plurality of focus windows. The method may also include determining a focal distance for each window. Further, the method may include determining near, far, and target focus distances. The method may also include calculating a stereo-base and screen plane using the focus distances.

1. Apparatus for determining image capture positions for creating a stereoscopic image of a scene, the apparatus comprising:
at least one processor and memory configured to:
receive image data of a scene captured at a first position by the image capture device;determine distances of predefined areas of the scene by use of focus information of image data corresponding to one or more predetermined areas of the scene;determine one of: a near distance defined as a distance with the smallest value, a far distance defined as a distance with the highest value, and a target distance defined as a focus distance of a target object in the scene;calculate the stereo-base of the scene using one of near distance, far distance, and target distances;determine a second position defined by adding the calculated stereo-base to the first position laterally to the scene;receive image data of a scene captured when image capture device is at the second position;utilize the image data captured at the first position and the second position to create a stereoscopic image; andutilize one of the near distance, the far distance, and the target distance to adjust at least one stereoscopic parameter of the stereoscopic image.
