摘要:

临床医学实践中,存留的人体异物会给病人身心带来严重的伤害。因此,快速、准确地对人体内异物进行三维定位,具有重要的研究意义和广泛的应用前景。文中对异物图像预处理、几何校正以及人体异物定位测量等关键技术进行了深入分析和研究,并设计开发了基于Matlab GUI的人体异物图像测量分析软件。该软件系统能实现对医学图像的预处理以及对人体内异物平面位置和深度信息的定量描述,实验结果表明,系统测量误差不超过0.21 mm。

关键词: 图像处理, 几何校正, 系统标定, 异物定位, 采点测距

Abstract:

In the clinical medical practice, small foreign object in the human body has brings to the patient a great impact of the physical and mental. Therefore quickly and accurately to three- dimensional location the foreign object in human body, has significant research value and application prospect. This paper focused on image preprocessing, geometric correction and human body localization carried on the thorough analysis and research,and designed the foreign object measurement and analysis software based on GUI MATLAB. The software system can realize the pretreatment of medical image and the quantitative description of the plane position and depth information of the foreign object. The experimental results show that the system measurement error less than 0.21mm.

Key words: image processing, geometric correction, system calibration, foreign object localization, ranging
