Embodiment 1

[0031] At present, when smartphones take photos, the working parameters of the camera involve two resolutions. One is the resolution of the preview image displayed in real time on the screen of the mobile phone, and the other is the shooting resolution of the photo (hereinafter referred to as the original image) stored after the photo is taken. The preview resolution is much lower than the shooting resolution. For example, the shooting resolution of a mobile phone can reach 4160x2336 pixels (10M), and the preview resolution is 1280x720 pixels; and the shooting resolution has various sizes for users to choose.

[0032] The mobile phone aimed at in the present invention is a mobile phone with a single rear camera, and the scene of 3D stereoscopic photography is also aimed at a static scene. In the present invention, according to the process of 3D stereoscopic photography, it is divided into two stages. The first stage is similar to the ordinary 2D photographing process, such as...

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...
