3D stereo shooting method for mobile phone

Abstract

The invention discloses a 3D stereo shooting method for a mobile phone. The method comprises: step 1, shooting; after a shooting process is completed, obtaining a preview image P0 at a time t0, an original image Img0, a key point K acquired by a key point extraction module in a region of interest R, and posture information of the mobile phone at the time t0; and step2, performing real-time 3D rendering on two views of a current viewpoint and a viewpoint at the time t0 according to current parallax information output by a parallax estimation module, and displaying the information on a screen; and by a user, adjusting an optimal posture and position of a camera according to a real-time stereo image effect displayed on the screen and OSD prompt information, thereby obtaining an optimal 3D effect picture. According to the 3D stereo shooting method for the mobile phone, by utilizing a 3D display function of the existing mobile phone, one view shot at a previous time and a real-time view of the current view point are processed and then are subject to 3D stereo display, so that the user directly see the final 3D stereo effect; therefore, 'real-time display and real-time shooting' user experience is implemented, and the optimal 3D effect picture is shot.

Description

technical field [0001] The invention belongs to the technical field of 3D photographing, and relates to a photographing method, in particular to a mobile phone 3D stereoscopic photographing method. Background technique [0002] With the development of 3D digital technology, more and more mobile phones with 3D display functions have begun to appear on the market. For example, ZTE Tianji 7MAX and SuperD D1, which were released in 2016, all support naked-eye 3D display; at the same time, more and more VR Glasses can also be combined with ordinary mobile phones to achieve 3D stereoscopic display of 3D content, so 3D photos / pictures will be more and more widely needed. How to adopt existing ordinary mobile phones (single rear camera) to take 3D stereoscopic photos will become more and more important. [0003] The basic principle of 3D stereoscopic photography is mainly to imitate binocular viewing, and shoot the same scene from two viewpoints with slight angle differences on the...

AI Technical Summary

Problems solved by technology

This solution has many assumptions about the angle of view / attitude of the mobile phone camera during the shooting process. At the same time, it has high design requirements for the processing algorithm, and the photo effect is difficult to be satisfactory.
