基于三基色相机的快照式光谱成像研究

Study of Snapshot Spectral Imaging Based on Three Primary Colors of Camera

现实场景瞬时多变,快照式光谱成像仪可以获得瞬变目标场景的光谱信息和空间信息.虽然三基色相机只有RGB三个通道,但是曝光时间短,分辨率高.为此,提出一种基于光谱数据库色度匹配的三基色彩色图像多光谱重建模型.通过对比现实场景采集的实际光谱图和重建光谱图,表明该模型能较好的将三基色彩图重建为窄带多光谱图像.

Real scene change instantly, snapshot spectral imaging can instantly obtain spectral and spatial information of the object. Three primary color camera has only three RGB three channels, but it has the advantage of shorter exposure time, higher resolution. For this, a mode is proposed which based on database and color matching for the reconstruction of multi-spectral imaging form primary three colors of images. Through the comparison of real scene spectrogram and reconstruction spectrogram, the results show that this model can reconstruct narrow band multi spectral image from primary three colors images accurately.
