一种用于POCT的嵌入式实时图像采集处理系统

本文设计并构建了一种基于带有数字处理模块FPGA的实时图像采集处理系统，介绍了该系统的软硬件设计和构建流程。调试结果表明该系统能在TFT显示屏上实时显示130万像素，15fps的视频图像。该系统可用于POCT（Point-of-care Test）中生化分析结果中图像信号的采集和处理，为POCT仪器提供了一种新的硬件平台。实验结果表明，该系统提供的高分辨率的彩色图像能够满足生化分析中图像信号的检测工作。

A Novel Real Time Image Collection System for Point-of-care Test

This article designs a real time imaging collection system based on CMOS+FPGA devices embedded with digital processing model, and illustrates the hardware and software design of this imaging system. Experiments show that the produced sample succeeds in displaying 1.3 mega-pixel, up to 15 frames per second (FPS) video in real time on the TFT screen of the system. The system can be utilized for collection and processing in the area of biomedical analysis, and supplies a new hardware platform for POCT devices. Experiments combined with biochemical analysis support that image inspection in biochemical analysis can be done after obtaining high definition colorful image data from this system.
