摘要
设计了一种基于NiosⅡ红外高速图像采集系统。该系统通过NiosⅡ软核处理器实现了基于Sobel算子的图像边缘检测算法,加上外围的红外探测器、SDRAM、高速DAC等器件,完成了高速红外图像采集和显示。其设计方法是基于一种系统级电路,通过QuartusⅡ和SOPC Builder实现对此系统的定制。测试结果表明,此高速红外图像采集系统性能稳定可靠,可以完成红外图像的实时采集、存储和显示。系统可以用在高帧频、数据量大的红外图像实时采集。
A high-speed infrared image acquisition system is designed based on Nios 1I. The algorithm of the image edge detection based on the Sobel arithmetic operators is used by the Nios ]I soft core. With the external infrared detectors,SDRAM and high-speed DAC devices, the algorithm completes a high-speed infrared image acquisition and display. The design approach of this system results from a system-level circuit, which can realize the customization of this system through Quartus 1] and SOPC Builder. According to the experiment result, the system is reliable and it can perform real-time acquisition of infrared image stably. The system can be used in high frame rate, real-time acquisition of infrared images of large volumes of data.
