摘要
为了测量具有高反射率表面的物体,提出了一种高动态范围三维测量方法,利用彩色相机红(R)、绿(G)、蓝(B)三通道光强不同的特性,融合获取高动态范围(HDR)条纹图片。利用π相移背景归一化傅里叶变换轮廓术去除环境光的干扰,减小物体表面反射率的影响,获取三维形貌。实验表明本方法能有效测量具有高反射率表面的物体。与其他方法相比,本方法投影的条纹较少,测量效率较高。
In order to measure objects with high reflectivity surface,a high dynamic range 3D measurement method is proposed in this paper,which can fuse and obtain high dynamic range(HDR)fringe images by taking advantage of the different light intensity characteristics of red(R),green(G)and blue(B)channels of color camera.The interference of ambient light was removed byπphase-shifting background normalized Fourier transform profusion,the influence of surface reflectance was reduced,and the three-dimensional morphology was obtained.Experiments show that this method can effectively measure objects with high reflectivity surfaces.Compared with other methods,this method has fewer projected fringes and higher measurement efficiency.
