摘 要:针对手部掌形的表皮纹理复杂性和弹性易形变等特点,提出了一种以光栅式双目三维视觉技术对手部掌形模型进行重构及实现的方法。首先对左右侧相机的属性参数和相对位置进行标定,并利用多方位光栅扫描的图像作优化拼接,再对海量原始数据点云进行编辑、三角形和曲面片化处理,最后实现手部掌形模型的数控模拟和实际加工验证。试验结果表明,采用高精度的非接触式测量能快速完成逆向实物加工,该方法具有借鉴和应用价值。Aiming at the characteristics of complicated texture epidermis and elasticity deformation of hand and palm form,a reconstruction and implementation method for building the model of hand-shape based on the technology of raster binocular system in vision metrology is proposed.The 3D vision measurement system is employed to calibrate the character parameter,attribute parameters and relative position of cameras in left and right side.Firstly,by two finished calibration cameras performance,we acquire data of photographed multi images from the hand-shape model with raster binocular system and global data optimization registration are accomplished.Then on this basis,the massive original point-clouds data are compiled.Finally,the hand shap model is simulated with numerical control and is also verified by practical processing.The experimental results demonstrate that the reconstruction modelwith non-contact measuring method is of high precision,good practicality and valuable to be referenced and promoted in application.
