项目摘要

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.

提出了一种同时测量物体表面光谱反射率和三维形貌的方法。光谱反射率从多波段图像获得。通过对这些多波段图像的立体匹配来估计形状。立体匹配的精度取决于模板匹配对立体图像中对应点的精确检测。该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立体匹配相比，多波段立体匹配具有更高的精度。
