| 针对自适应条纹投影方法需要多个投影图案确定最佳投影强度，效率较低的问题，提出了一种高效的自适应条纹投影方法，该方法仅需一张全白图像和一张亮度较低的图像，即可自动确定最佳投影强度。根据物体表面像素之间的灰度值变化量化物体表面的反射率，自适应地确定最佳投影强度。实验结果表明，所提方法能够有效避免饱和像素生成，实现高反射物体的精确测量，在效率方面具有性能优势，与传统条纹投影方法相比，测量均方根（root mean square，RMS）降低了47%，显著提高了测量精度。 |

| Aiming at the problem that the adaptive fringe projection method requires multiple projection patterns to determine the optimal projection intensity, resulting in low efficiency, an efficient adaptive fringe projection method is proposed. This method only requires one all-white image and one image with lower brightness to automatically determine the optimal projection intensity. According to the change in grayscale values between pixels on the object surface, the reflectivity of the object surface is quantified, and the optimal projection intensity is determined. Experimental results show that the proposed method can effectively avoid the generation of saturated pixels and achieve accurate measurement of highly reflective objects. It has performance advantages in terms of efficiency. Compared with the traditional fringe projection method, the root mean square is reduced by 47%, significantly enhancing measurement accuracy. |
