Quick generating method for integral imaging micro image array based on GPU

Abstract

The invention provides a quick generating method for an integral imaging micro image array based on a GPU. The method comprises the process of establishing a virtual camera array to obtain a disparity image array in a Direct3D program and the process of achieving the operation that the disparity image array is quickly converted into a micro image array in a CUDA program. A simplified virtual camera array structure is established based on the computer graphics library Direct3D to carry out rendering on a virtual scene, and the efficiency of generating all the information of the micro image array is improved; the quick generation of the micro image array is completed based on the characteristics of a CUDA parallel computing architecture, data transmission in a CPU and a GPU is barely needed to be carried out through a computer system bus, and therefore the efficiency of generating the micro image array is further improved. Through the method, the speed of generating the integral imaging micro image array is increased by tens of times and even hundreds of times compared with the generation based on the CPU, and the requirements of real-time dynamic integral imaging 3D display are met.

Description

technical field [0001] The present invention relates to integrated imaging 3D (three-dimensional) display technology, and more specifically, the present invention relates to a method for rapidly generating integrated imaging micro-image arrays based on GPU (Graphics Processing Unit). Background technique [0002] Integrated imaging is an important 3D display technology, and viewers can watch stereoscopic images without wearing vision aid glasses. With the rapid development of computer technology, people widely use computer to simulate and process various optical processes, and derive computer integrated imaging technology. The technology first uses 3D modeling software to establish a 3D scene model, and then uses a computer program to establish a camera array to simulate the imaging process of the microlens array, so as to obtain the source of integrated imaging, that is, the microimage array. [0003] Multi-viewpoint rendering computer-integrated imaging is a technology th...

Problems solved by technology

Since the number of lens elements in integrated imaging is huge, and the number of renderings to the 3D virtual scene is equal to the number of lens elements, the computer rendering process will consume a lot of time, and it is difficult to meet the requirements of real-time dynamic computer integrated imaging
