Problems solved by technology
[0005] However, in the prior art, since the captured photos themselves do not carry depth data, the depth data simulated by the superpixel synthesis algorithm is not accurate, resulting in distortion of the synthesized 3D content, which is not a real 3D image

The invention discloses a method and device for realizing a three-dimensional image by using dual cameras. The method includes: using a first camera to obtain image information of a target object and sending it to an image signal processor; using a second camera to collect image information of the same viewing angle The phase grating image with fringe deformation occurs, and the depth of field data of the target object is calculated, and sent to the image signal processor; after the image signal processor receives the image information and the depth of field data, if it is judged to be the depth of field data, the The depth of field data is directly transmitted to the 3D image generation module, and if it is judged to be image information, conventional image signal processing is performed; the depth of field data and the image information after image signal processing are synthesized by the 3D image generation module to generate 3D images, through the present invention, real-time, high-fidelity 3D photos and videos can be realized.
Description
technical field [0001] The invention relates to a method and a device for realizing a three-dimensional image, in particular to a method and a device for realizing a three-dimensional image by using dual cameras. Background technique [0002] With the rapid development of smart phones, the differences between them are getting smaller and smaller. They have similar configurations and similar designs. Therefore, smart phones need some "new features" to attract users' attention again. Through the analysis of users' usage habits, in addition to the basic functions of calling and surfing the Internet, cameras are used more frequently by users. The demand for front or rear dual cameras has begun to be sought after by major smartphone manufacturers and recognized by users. The photos taken by the dual camera have higher resolution, better noise control, better dynamic range, and more accurate depth of field data, which are more favored by users. [0003] Taking 3D (Three Dimensio...
