Study for simultaneous measurement of spectral reflectance and three dimensional shape of object surface

提出了一种同时测量光谱反射率和物体表面三维形状的方法。光谱反射率是从多波段图像获得的。通过对这些多波段图像进行立体匹配来估计形状。立体匹配的精度依赖于通过模板匹配在一对立体图像中精确地检测对应点。这种方法的优点是可以在多波段图像中检测到RGB图像中丢失的低对比度颜色纹理。实验结果表明，与RGB立体声匹配相比，多频段立体声匹配具有更高的精度。

A method for simultaneous measurement of spectral reflectance and three dimensional shape of object surface is proposed. Spectral reflectance is obtained from multiband images. The shape is estimated by stereo matching of these multiband images. The accuracy of stereo matching depends on precise detection of corresponding points in a pair of stereo images by template matching. This method has the advantage that low contrast color textures that are lost in RGB images could be detected in the multiband images. Experimental results show that multiband stereo matching is accurate in comparing with RGB stereo matching.
