摘　　要：在目前的图像实时采集方法中,对采集到的图像信号的噪声滤波不足,影响采集图像的质量。因此,提出基于计算机技术的高速串行光纤图像实时采集方法设计研究。采用计算机技术中值滤波法,对采集到的图像进行数据滤波去噪。通过Mallat算法将去噪后的图像进行分解并重构小波函数,获得完整的图像数据信号,进一步分析和变换重构后的小波函数。通过链码方式提取图像的轮廓和特征链码,实现图像采集。实验结果显示,设计的图像采集方法采集到的数据受噪声影响更低,信噪比改善因子的均值分别为-5.9762和-4.6691,并且图像质量更好,因此,证明研究方法满足设计目的,有效提高了采集图像的质量。In the current real-time image acquisition methods,the noise filtering of the collected image signal is insufficient,which affects the quality of the collected image.Therefore,the design and research of high-speed serial optical fiber image real-time acquisition method based on computer technology is proposed.The median filtering method of computer technology is used to filter and denoise the collected images.Mallat algorithm was used to decompose the denoised image and reconstruct the wavelet function,so as to obtain the complete image data signal,and further analyze and transform the reconstructed wavelet function.Image acquisition is realized by extracting contour and feature chain code of image by chain code method.The experimental results show that the data collected by the designed image acquisition method is less affected by noise,the mean of SNR improvement factor is-5.9762 and-4.6691,respectively,and the image quality is better.Therefore,it proves that the research method meets the design purpose and effectively improves the quality of the collected image.
