Comparing with the traditional mono-energy X-ray imaging inspection system, dual-energy X-ray transmission imaging system has the ability of simple object identification. It can automatically classify the materials into organic, inorganic and mixture signing with different colors. In order to enhance the object identification ability of dual-energy imaging system, HSB color model was applied in pseudo dual-energy X-ray transmission imaging system and the special method of color mapping was used for signing pixel colour in this paper. The experiments on 1/3 scale system show that the object identification ability is improved by using HSB color model.%与传统的单能X射线成像安检设备相比,双能透射成像系统具有简单的物质识别功能,可将被检物品自动分为有机物、无机物和混合物3大类,并分别赋予不同的颜色.为提高双能系统的物质识别能力,本文将HSB色彩模式应用于伪双能X射线透射成像系统中,采用特定的颜色映射方法给像素点配色.在1/3规模样机上进行的实验结果表明,HSB色彩模式可提高双能成像系统的物质识别能力.
