A method and mobile terminal for taking 3D photos

Abstract

An embodiment of the invention discloses a method for shooting 3D (three dimensional) images and a mobile terminal. The position of a photosensitive component remains unchanged in a shooting process. The method comprises the following steps: focusing a first point group of a target object and acquiring a first image, wherein the first point group is located in a first plane; focusing a second point group of the target object and acquiring a second image, wherein the second point group is located in a second plane, and the first plane and the second plane are non-coplanar; calculating position information of the first point group according to the first image and calculating position information of the second point group according to the second image, wherein the position information comprises direction information of points, distances between the planes in which the point groups located and the plane in which the photosensitive component located, and central distances between the points and centers of the images; and establishing a 3D model of the target object according to the position information of the first point group and the second point group. Through the method for shooting 3D images and the mobile terminal, a user can acquire the 3D images of the target object without changing a shooting position; the requirements on the user are low; the shooting process is simple.

Description

technical field

[0001] The invention relates to the field of 3D photographing, in particular to a method for photographing 3D photographs and a mobile terminal. Background technique

[0002] Pioneers in the field of photography have been working to create more realistic photos, ie 3D photos capable of presenting 3D images. 3D refers to the three dimensions of space, and 3D images refer to images with a three-dimensional effect. Generally, you need to use 3D glasses to experience the 3D effect. With the rapid development of virtual reality VR, 3D images are currently being used more and more. At present, there are many schemes to take pictures of the subject through the shooting module of the mobile terminal, and form a 3D picture of the target object through post-processing.

[0003] At present, users need to hold a mobile terminal to rotate around the subject, take pictures of the subject from different shooting directions, and obtain the 3D point cloud of the subject fro...
