针对并行彩色共聚焦测量系统在进行三维重构时质心识别效果差,处理效率低等相关问题,本文提出一种高效率高精度的三维重构方法。该方法首先对三维重构实验得到的所有图像进行目标提取和图像拼接,得到待处理的拼接图像;其次,通过MATLAB的regionprops函数和形态学处理提取拼接后各个被测点的质心及质心连通区域,并利用颜色转换算法进行相应的“
H
值-高度”转换;最后,比较并结合插值拟合算法实现物体表面三维形貌的重构。为了验证该算法的可行性,文中针对一元硬币的“N”字和“E”字进行处理。实验结果表明,该系统的轴向测量范围为80 μm,测量精度可达到微米级别。经验证:该算法可以快速有效地实现物体表面三维形貌的还原,且相较于传统方法,处理效率提高5~6倍。
In order to solve the problems of poor centroid recognition and low processing efficiency in 3D reconstruction of parallel chromatic confocal measurement system, a high efficiency and high precision 3D reconstruction method is proposed in this paper. In this algorithm, target extraction and image splicing were performed on all of the experimental images to obtain the spliced images. And using the ‘regionprops’ function in MATLAB, the centroid and its connected area of each measured point were extracted, and then the relationship for H value and height was constructed with the method of color conversion algorithm. Finally, the interpolation fitting algorithm is used to reconstruct the 3D surface topography of the object. In order to verify the feasibility of the algorithm, the letter ’N’ and ‘E’ on the coin of one-yuan was measured in author’s self-built parallel chromatic confocal system. The experimental results showed that the axial measuring range of the system was 80 μm. Therefore, the measurement accuracy can reach micron level, and this algorithm can quickly and effectively reconstruct the 3D surface topography of sample. Compared with the conventional method, the processing efficiency is 5~6 times higher.
