摘要
针对脊柱生物力学测量的重要意义,在LabVIEW开发环境中构建基于图像处理技术快速获取脊柱运动范围（ROM）的测量系统。运用LabVIEW中的机器视觉模块对采集到的原始脊柱图像进行预处理后提取标记针角度信息,最终获得脊柱的ROM。选取6具T7-T10节段人体脊柱标本,实施左/右侧弯、前屈、后伸、顺/逆时针扭转6个方向上的加载,利用该系统测量在载荷为1-5N·m时T8-T9节段的ROM。实验结果表明,该系统能够精确、快速地测定脊柱的ROM,为脊柱生物力学研究者提供了操作简便可靠性强的测量工具。
A measurement system based on the image processing technology and developed by LabVIEW was designed to quickly obtain the range of motion （ROM） of spine. NI-Vision module was used to pre-process the original images and calculate the angles of marked needles in order to get ROM data. Six human cadaveric thoracic spine segments T7-T10 were selected to carry out 6 kinds of loads, including left/right lateral bending, flexion, extension, cis/counterclockwise torsion. The system was used to measure the ROM of segment T8-T9 under the loads from 1 N .m to 5 N .m. The experimental results showed that the system is able to measure the ROM of the spine accurately and quickly, which provides a simple and reliable tool for spine biomechanics investigators.
