三维重建中真实感纹理再现的一种有效方法

结合颜色视觉理论的发展以及影像匀光技术,分析成像对象在光照下的表面光学现象,依据颜色视觉的感知过程建立简单的数学模型描述成像时刻光照环境对影像色调的影响、模拟视觉亮度和色度恒常机制,通过计算获得色度均匀、自然的环境散射光照射下的纹理影像,为三维重建中真实感纹理再现提供了一种简单、有效、快速的方法。并通过两组实验数据进行了验证。

Effective Method on Realistic Texture Rendition in Three Dimension Reconstruction

Combined with the development of color vision theory and image dodging technology, the surface reflection of imaging object in illumination is analyzed, a simple arithmetic model is constructed to illustrate the effect on image tone in the illumination environment at the imaging time based on the perception process of color vision. The model simulates vision light and chromatic constancy mechanism, a texture image with uniform chromatic and light, nature appearance can be obtained through calculation. Two sets of data are processed by such algorithm and the result shows that it's a simple, effective, fast way for realistic texture rendition in three dimension reconstruction.
