摘要
步枪射击运动立姿状态时人体下半身形态和正常站立形态有明显差异,对其姿态特征进行研究可为射击裤的版型设计提供参考。研究采用无接触式三维扫描仪获取人体模型,用逆向工程软件Rapidform进行测量,分析立姿射击状态时运动员下半身皮肤尺寸变化,结合CorelDRAW测量角度,探究步枪射击运动裤装结构与下肢姿态变化的关系。对围度、长度和角度的变化进行分析,结果表明下半身尺寸变化中,腰围、腹围、臀围呈现增大趋势,男性增大2 cm左右,女性增大依次为3.65、2.22、0.93 cm。左腿内侧和右腿外侧呈缩短趋势,左腿内侧男性缩短2.73 cm、女性缩短4.52 cm;右腿外侧男性缩短3.85 cm,女性缩短2.03 cm。角度变化中,腰围角度变化为8°~9°,右小腿围角度变化为10°~12°,右腿内侧角度变化为8°~10°。
There is a significant difference between the lower body shape of the human body and the normal standing posture during rifle shooting.The study of its posture characteristics can provide references for the design of shooting pants.A non-contact 3D scanner was used to obtain a human body model,and the reverse engineering software Rapidform was used for measurement,combined with CorelDRAW measurement angles.The changes in the skin size of lower body of athletes in standing shooting state were analyzed,and the relationship between the structure of the rifle shooting pants and the posture of the lower limbs was explored.The results showed that the waist circumference,abdominal circumference and hip circumference increased by about 2 cm for men,3.65 cm,2.22 cm and 0.93 cm for women.The inner side of the left leg was shortened by 2.73 cm for males and 4.52 cm for females,and the outer side of the right leg was shortened by 3.85 cm for males and 2.03 cm for females.Among the angle changes,the waist circumference angle changed to 8°~9°,the right calf circumference angle changed to 10°~12°,and the right leg inner angle changed to 8°~10°.
