【摘要】 本文提出了一种用于测量运动物体三维面形的频闪结构光照明系统。使用该系统的位置监测装置自动跟踪检测旋转物体的转动信息,用该信息同步控制光源发光和摄像系统同时工作,记录下闪光时刻旋转物体的瞬间图像。该系统成功运用到家用电风扇叶片的三维面形实时测量研究中,能够准确地获得旋转叶片的瞬间静止图像,重建旋转叶片每个瞬间时刻的三维面形。同时,该系统还具备人工设定光源发光频率的功能,可以拓宽应用到无重复特征信号的高速运动物体的瞬间三维面形的测量。更多还原

【Abstract】 A stroboflash structured illumination system, which can be used in measurement for 3Dshape and deformation of high-speed motion object, is proposed and verified by experiments. Thesystem, present in this paper, can automatically detect the position of high speed moving object andsynchronized control the LED flash and the image grabber acquiring an image of motion object, alsocan create a signal artificial setting to synchronized control the LED flash and image grabber. We successful acquire a serial of sharp and clear images of rotation blade of electric fan and reconstruct its 3D shapes in difference revolutions.更多还原
