本文利用ＣＴ成像技术和计算机数字化图像处理系统的图像分析功能，对２５例男性（１８岁～２３岁）样本进行全身ＣＴ横断层扫描。将获得的断层图像依次输入ＩＭＧ２型图像处理系统中。根据图像中各组织的灰度以及各种组织的比重值，对其进行处理、分析和测算，综合计算出每例样本整体及各体段的质量和质心位置等惯性参数。再经对比、验证和统计学检验，确立其准确性和可靠性，为建立中国人体惯性参数模型提供了重要数据。也为体育项目训练提供了可靠的依据。
In this study, CT scan was performed in 25 male (18-23 years old) samples using CT imaging and image analysis of computerized digital image processing system. The obtained tomographic images are sequentially input to an IMG2 type image processing system. According to the grayscale of each tissue in the image and the proportion values of various tissues, it is processed, analyzed and measured. The inertial parameters such as mass and centroid position of each sample are calculated. And then by comparison, verification and statistical tests to establish its accuracy and reliability, to provide China’s body inertia parameter model provides important data. It also provides a reliable basis for sports training.
