摘要
提出了一种对激光光斑的CCD数字图像进行预处理的方法。借助于目前广泛使用的计算机软件MAT-LAB和Origin,利用MATLAB的图像处理工具箱对激光光斑的原始CCD图像进行去噪,并使用Origin软件的曲线拟合和FFT平滑功能对光强分布曲线进行了平滑处理。实验结果表明,进行图像预处理后的原图像噪声被有效地抑制和消除,光强分布较为平滑。
A method to preprocess the CCD digital image of laser spot is proposed. Using the image processing toolbox of MATLAB, the noise removing treatment on original CCD image of laser spot is performed. And the smoothing treatment on intensity distribution curve is achieved by using the curve fitting and FFT smoothing functions of Origin software. The experimental results show that,the noise of original image is effectively suppressed and ridded after the preprocessing treatment, and the intensity distribution is comparatively smooth.
