Design and research of laser medical image acquisition system

为了解决传统FPGA医学图像采集系统存在的偏差高和效率低的问题,设计并实现基于双核OMAP3530处理器的激光医学图像采集系统,分析系统的总体结构,详细说明了图像采集模块、处理器模块以及存储器模块的设计和器件选择。物体被两种不同的激光源照射,反射出的激光射入激光传感器后,获取物体的激光条纹图像,图像采集模块获取物体的激光条纹图像数据,并将图像数据传输到OMAP3530处理器进行处理,处理后的数据存储到MT29CIG24MADLAJA-6IT存储器模块中。系统软件部分分析了图像采集模块以及图像存储模块的实现过程。实验结果说明,所设计图像采集系统具有较高的图像采集效率和精确度。

In order to solve the deviation existed in traditional FPGA medical image acquisition system and the problem of low efficiency,laser medical image acquisition system based on OMAP3530 dual-core processor was designed and implemented. In this paper,the system general structure was analyzed,the designs and components of the image acquisition module,processor module and storage module were elaborated in details. Objects were illuminated by two different kinds of laser sources,and obtained the laser stripe images after the reflected laser incidents into laser sensor. The image acquisition module collected the laser stripe image data of the object,and transmitted to OMAP3530 processor,then,to be stored in MT29 CIG24 MADLAJA-6 IT memory module. System software part analyzed the realization processes of image acquisition module and image storage module. Experiment result shows that the design of image acquisition system has higher image acquisition efficiency and accuracy.
