Abstract

The invention discloses an augmented reality system and an augmented reality method based on Zynq software and hardware coprocessing. The augmented reality system comprises a Zynq main processor, a USB Camera, a USB control chip, a DDR3SDRAM, an SD card, an SDRAM and a VGA display, and is mainly used for realizing processing and display of the augmented reality system. The augmented reality system is characterized in that: the Zynq main processor comprises a processor system and an FPGA, and the processor system introduces identification images and calculates internal parameters of the USB camera; and the FPGA preprocesses an image acquired by the USB camera, transmits a preprocessing result back to the processor system through an AXI bus, calculates external parameters of the USB camera, subjects a virtual image and a real image to real-time fusion, and displays the fused image on the VGA display. The augmented reality system and the augmented reality method have the beneficial effects of being fast in processing speed, good in real-time performance and high in processing capability, enhancing user experience, being capable of reducing system power consumption, and having universality.

Description

technical field [0001] The invention relates to the field of computer augmented reality, in particular to an augmented reality system and method based on Zynq software and hardware cooperative processing. Background technique [0002] Augmented reality (augmented reality, AR) technology is a new technology that "seamlessly" integrates real world information and virtual world information. , by seamlessly and naturally superimposing virtual 3D information such as computer-generated graphics, text, and annotations into the real-world scenes seen by users, so as to expand human cognition and perception of the world. [0003] The architecture of the traditional embedded augmented reality processing system is as follows: the camera collects real-world images, the ARM processor preprocesses the real-world images, and then performs logo recognition, 3D registration and virtual-real fusion, and finally transmits the rendered images to the display for further processing. real-time di...
