Embodiment Construction

[0034] figure 1 It is the overall block diagram of the omnidirectional visual system based on SOPC technology of the present invention, and its composition comprises: fisheye lens 1, CMOS image sensor 2, SOPC system 3, Nor Flash4, SDRAM5, SD card 6, button 7, LCD display 8, The specific implementation method of the system is as follows:

[0035] 1. Realization of the overall system architecture: the fisheye lens 1 and the CMOS image sensor 2 form a camera module, through which the omnidirectional visual image information larger than the hemispherical field of view (360°x180°) is obtained, and the image data is transferred in a certain time sequence Output to SOPC system 3; SOPC system collects all-round visual distortion images, and performs real-time distortion correction, then outputs the original distorted image data or corrected image data in a certain time sequence, and previews and displays through LCD display 8; Nor Flash4 and SOPC The CFI Flash control pin in system 3...

Abstract

The invention discloses an all-dimensional visual system based on an SOPC. According to the all-dimensional visual system based on the SOPC, (1) a fish-eye lens and a CMOS image sensor are used for obtaining all-dimensional visual image information of a view field larger than a hemisphere; (2) a Nios II/SOPC system is established in an FPGA chip by configuring an IP module based on the SOC technology and FPGA programmable features, and a user-defined IP is designed to achieve system core functions such as real-time collection, distortion correction and display of all-dimensional visual images; (3) a Nor Flash is used for storing FPGA configuration files and system software, an SD card is used for storing image files, and an SDRAM serves as an internal storage device of the system; (4) keys and an LCD displayer serve as a man-machine interaction unit of the system. The all-dimensional visual system solves the problems that the real-time collection, correction, storage and display of images cannot be achieved in small embedded devices through an existing all-dimensional visual system establishing method. The all-dimensional visual system has the advantages of being small in size, low in cost and high in function expandability.

Description

technical field [0001] The present invention relates to the field of machine vision, and more specifically relates to an SOPC-based omnidirectional vision embedded system capable of realizing real-time acquisition, distortion correction, storage and display of omnidirectional vision images. Background technique [0002] Omnidirectional vision refers to obtaining all visual information larger than the hemispheric field of view (360°x180°) at one time, so it is of great significance in all walks of life that rely on visual information to make decisions. At present, there are mainly four construction methods for building an omnidirectional vision system: 1) The method of ordinary vision sensor + rotating pan / tilt. , there is a time delay in the obtained image, which is not suitable for visual information acquisition of fast-moving targets; 2) The method of multi-visual sensor + image stitching uses multiple visual sensors to simultaneously acquire visual images from different a...
