由于投射到物体表面的激光条纹因被调制在条纹不同位置处其宽度也各不相同。因此不能确定合适的拟合数据使得高斯拟合法的提取精度较低。针对此情况，提出了改进的高斯拟合法来进行激光条纹中心线提取，当激光条纹宽度发生变化时，通过边缘增强，图像分割，去噪处理后获得合适的拟合数据长度。实验结果表明：这种改进的高斯分布的曲线拟合算法在测量中更具有可行性，且提取精度得到提高，更适合于光条中心线提取。

A The laser strips projected to object surface show different laser strip widths at different laser strip positions .Laser strip center line extraction with Gaussian fitting has low accuracy because choosing correct fitting data are difficult. In this paper, a new method for extracting laser strip center line has been proposed . When the laser stripes width is changed, through the edge enhance, image segmentation, noise filter gain the suitable fitting data length. Experiments show that ： this improvement of the Gaussian distribution curve fitting method is more feasible, and extraction accuracy is improved, and more suitable for eenterline article light extraction in the measurement.
