【摘要】：最近几年,嵌入式技术在集成电路大规模发展的带动下发展迅速,在工业控制、智能控制、医疗、电子等方面都发挥着重要的作用。近年来,嵌入式产品在医疗卫生方面的应用日渐广泛。研究嵌入式在医疗方面的研究对推动医疗的发展有着重要的意义。目前在医学界图像采集已经基本处于成熟阶段,但在牙科设备中,对牙的图像采集还采用利用X射线装置来生成胶片的手段。这种方法由于技术成熟、工艺稳定的优点而备受牙科医生的推崇和肯定。但这种方法不仅浪费资源,而且不便于图像的精确查看和保存。本设计利用ARM处理器设计的图像采集设备,并且将采集的图像实时的在显示屏上可以直接显示出来,而且可以对图像做相关的处理。这不仅成功的解决现存的问题,而且使嵌入式先进技术更好的应用到牙医设备中。医生通过操作此牙医手持终端,可以将患者的牙齿图片拍摄出来,并且对图片做相应的放大缩小图片,便于更好的查看病情。对于更好的了解患者的牙齿状况,作出更好的治疗有着实际意义。论文的主要研究内容主要包括U-boot的设计、Linux的移植、文件系统的挂载和软件的实现几个部分。硬件采用了QQ2440开发板,QQ2440开发板上的处理器是S3C2440,触摸屏为NEC的TFT液晶屏。软件部分主要是介绍U-boot的改写和移植,Linux内核的裁剪和移植,文件系统的挂载和驱动和软件的编写几大部分。通过CCD专业设备来采集牙齿的图像数据,然后将相关的数据传输到处理器,处理器通过处理将图像数据显示在触摸屏上。医生通过操作触摸屏,便可以对图片做相应的处理。
[Abstract]:In recent years, rapid development of embedded technology in the development of large-scale integrated circuit driven, in industrial control, intelligent control, medical, electronic and other aspects have played an important role. In recent years, the embedded products are widely used in the health sector. The research of embedded in the medical field has important significance for promote the development of health care.
Image acquisition in the medical profession has been basically in the mature stage, but in dental equipment, dental image acquisition by using X ray device to generate the film. Since this method is a mature technology, has the advantages of stable technology and highly respected dentist and recognition. But this method is not only a waste of resources, but also not easy see the image exactly and saved. This design uses the image acquisition equipment ARM processor design, and real-time acquisition of images on the display can be displayed, and image related processing. It not only solve the existing problems, and the application of advanced embedded technology to better dental equipment. The doctor through the operation of this dentist handheld terminal, can the patient's teeth image capture, and the pictures do the corresponding picture zoom, better check It is of practical significance to better understand the tooth status of the patient and to make better treatment.
The main contents of this paper include the design of U-boot, Linux transplantation, several parts of the file system mount and software. The hardware used the QQ2440 development board, QQ2440 development board is S3C2440 processor, a TFT LCD touch screen NEC. The software part mainly introduces the rewriting of the U-boot and Linux kernel transplantation. The cutting and transplantation, file system mount and drive and software to write a few parts. Image data through the CCD professional equipment to capture the teeth, and then the data transmission to the processor, the processor by processing the image data displayed on the touch screen. The doctor through the operation of the touch screen, and can do corresponding processing to the picture.
