Abstract
Disclosed are a method and apparatus for acquiring a three-dimensional image using two cameras. The method includes: acquiring image information of a target object using a first camera, and sending the acquired image information to an image signal processor; acquiring a phase grating image subjected to strip deformation in a picture space with an identical visual angle using a second camera, calculating depth data of the target object, and sending the depth data to the image signal processor; upon receipt of the image information and the depth data, if the image signal processor judges that the depth data is received, directly sending the depth data to a 3D image generating module, and if the image signal processor judges that the image information is received, performing routine image signal processing and sending the image information to the 3D image generating module; and synthesizing the depth data and the image information subjected to the image signal processing using the 3D image generating module to generate a 3D image.
