中文摘要：

为了解决三维人体建模中人体参数和尺寸提取的问题,提出基于图像的人体特征参数提取方法,进而对人体图像的各特征区域进行定位,并给出计算流程.对采集的图像进行预处理,再对人体正面和侧面图像特征点进行识别,从而识别出人体特征区域,提取出人体特征尺寸.阐述用模型法和参照法计算特征尺寸的方法与原理,推导出由图像像素计算特征尺寸的公式,分析模型法和参照法的优缺点,并结合两者的优点,提出模型参照法特征尺寸计算方法.利用实际采集的图像,根据模型参照法进行人体参数提取,结果表明,该方法能够方便、准确地从用户照片得到人体特征参数.

英文摘要：

A technique for feature point extraction of human body based on image was presented to solve the problem of body feature parameter extraction in three-dimensional human body modeling. Then each part of the human body in picture was distinguished,and the calculating process was given. First,the collected image was preprocessed,and then the front and side body feature points were identified to get body feature district,finally,the body feature sizes were extracted. The method to calculate the body feature sizes was introduced according to the modeling method and the reference method. Then a new method was proposed to improve the accuracy of body feature sizes. Human body feature parameters were obtained from the collected images by the modeling reference method. Results show that the method can accurately extract the feature points and the feature sizes.
