[Abstract] Objective In order to quickly and accurately determine the varieties of traditional Chinese medicine at low cost, 3D technology is applied to the identification of the true and false of traditional Chinese medicine. Methods As well as depth of field synthesis software, microscope and photographic equipment were used for 3D photographing and identification of common Chinese herbal medicines and their confusions. Results Through 3D technology, the distinction between the authentic and the confusions of traditional Chinese medicine had been completed, and the authenticity of traditional Chinese medicine can be preliminarily identified. Conclusion This method is simple and practical, improves work efficiency and reduces work cost. It is very suitable for popularization at the grass-roots level.

隨着经济的飞速发展和不断改革,我国中药材市场逐渐活跃。据文献报道[1-4],在市场上发现以次充好、以假乱真等现象严重,中药材鉴别手段也逐渐发生改变[5]。3D技术是将3D景深合成技术和3D大图拼接技术相结合的一种技术。3D景深合成是提取变焦非平面物体图像中的相对清晰区域,并进行图像融合得到一张立体、高清的图片。有些仪器具有自动景深合成的功能,也可以通过相关软件如Photoshop[6-8]、Combine ZP[6,9]等实现景深合成。3D大图拼接是将数张3D景深合成图像拼接成一张无缝高清全景图或高分辨率图像。在孙宝惠老师指导下收集临床常用、混淆品较多、肉眼难以鉴别的几类中药材,应用3D技术将细微鉴别特征放大,得到一张全景高清图,从而找其鉴别特征,为临床研究提供参考。
