摘要
为避免图像失真,研究基于三维激光视觉技术的平面设计图像增强和优化方法。采集平面设计图像数据,将三维激光映射至平面设计图像表面形成信息图,利用该信息与局部复杂度加权处理,构建平面设计图像直方图,扫描以及灰度值变换,消除平面设计图像噪声,采用分块局部增强方法分割图像直方图,实现平面设计图像的增强优化。实验表明,不同噪声标准差下,研究方法的峰值信噪比的平均值为36.62 dB,结构相似度平均值为0.9526。且该方法去噪效果较好;可有效增强平面设计图像的视觉效果,增强人眼甄别平面设计图像信息的能力。
In order to avoid image distortion,the image enhancement and optimization method of graphic design based on three-dimensional laser vision technology is studied.Collect the graphic design image data,map the threedimensional laser to the surface of the graphic design image to form an information map,use this information and local complexity weighting processing to construct the graphic design image histogram,scan and gray value transformation to eliminate the noise of the graphic design image,and use the block local enhancement method to segment the image histogram to realize the enhancement and optimization of the graphic design image.Experiments show that under different noise standard deviations,the average peak signal-to-noise ratio of the research method is 36.62dB and the average structural similarity is 0.9526.And this method has good denoising effect;it can more effectively enhance the visual effect of graphic design images and enhance the ability of human eyes to distinguish graphic design image information.
