基于FPGA的胶囊内窥镜图像采集系统

Image acquisition system of capsule endoscope based on FPGA

为了提高胶囊内窥镜的图像帧率,研制了一种基于FPGA的胶囊内窥镜图像采集系统。其内部包含了利用FPGA编写JPEG压缩核用于减少图像数据量。它主要由图像胶囊内窥镜,便携式图像接收器和计算机处理软件三部分组成。文中将详细讨论这三部分软硬件设计。本文完成胶囊内窥镜图像采集系统的原型系统搭建,测试结果表明原型系统达到设计要求。

To improve the frame rate of capsule endoscope, the paper develop an image acquisition system of capsule endoscope based on FPGA. The system contain a JPEG Compressor which is used to reduce the image data size. And the system is composed of three parts： image capsule endoscopes, portable picture receiver, Compute Processing software. The paper will discuss the software and hardware design of the three parts in details. The paper complete the image acquisition system prototype, and the test results prove the design is meet the previous requriment.
