【摘要】 介绍了在肠道内窥镜形状重建系统中的32通道USB数据采集卡的设计与应用。该采集卡采用通用串行总线(USB)接口方式,通过12位A/D转换芯片及多通道模拟开关,采集经过转换、放大的内窥镜镜体形变信号。在实验中,该数据采集卡达到了预期的设计要求,实时重建出了镜体形状。更多还原

【Abstract】 This paper presents the design and application of 32-channel data collection board based on USB in the shape reconstruction system of endoscope body. The board communicate with computer through the Universal Serial Bus (USB),and utilize 12-Bit A/D Converter and 16-Channel Analog Multiplexers to collect amplified analog signals.In the experiment, the data collection board meet the functional requirement ,and can reconstruct the real-time shape of endoscope body.更多还原
