Research on interior design system integrating digital processing technologyand image processing technology

为解决室内设计系统中图像去噪及渲染效果较差的问题,提出数字处理技术和图像处理技术相融合的室内设计系统,该系统的数据层将待处理图像传输到逻辑层,由数字处理模块使用新阈值函数的去噪算法对图像能量的分布特点加以考虑,各小波系数与自身大小相同的降噪因子相乘,实现图像去噪;图像处理模块使用双向反射分布函数模型模拟物体漫反射,结合Torrance⁃Sparrow微面元模型模拟物体高光反射,实现图像的渲染。逻辑层将处理完成的室内设计图像传输到应用层,通过PC端或浏览器界面展示室内设计结果。该系统去噪后图像平滑、清晰,边缘分割明显,图像渲染后反射效果和光线效果良好,且图像处理时间短,具有良好的室内设计效果。

An interior design system which integrates digital processing technology and image processing technology is proposed to improve the image denoising and rendering effect in such systems.In the data layer of the system,the image under processing is transferred to the logical layer.The denoising algorithm based on new threshold function is used by the digital processing module to take account of the distribution characteristics of the image energy.Each of the wavelet coefficients are multiplied by the denoising factors with the same size of the corresponding wavelet coefficients to achieve the denoising of the image.The bidirectional reflectance distribution function(BRDF)model is used by the image processing module to simulate the diffuse reflection of the object and also simulate the highlight reflection of the object in combination with the Torrance⁃Sparrow microplane metamodel,so as to realize the rendering of the image.The processed interior design image is transmitted to the application layer by the logic layer.The interior design results is displayed by PC or browser interface.After the application of the designed system,the image after denoising has smooth image,clear edge and distinct segmentation,and the reflection effect and light effect after image rendering are good.In addition,the system can spend short time to complete image processing.Therefore,it has a good interior design effect.
