多頻譜影像系統色彩穩定性之研究

A Color Stability Study on Multi-Spectral Imaging System

摘要


多頻譜影像技術是國際上許多現代化國家,在學術發展上主要的重點,其優勢在於提高每一影像畫素的色彩分析與記錄能力,並且藉由色彩校正程序,可以準確的分析所拍攝之物體的表面光譜反射特性,可以突破一般數位相機色域不足的困境,更可以解決長久以來因同色異譜的現象所造成的問題。而本研究所使用的多頻譜攝像機是國內外少數用於數位內容應用的新科技產品,為了確保未來在多頻譜影像掃描系統上的穩定性,本系統對多頻譜攝像機進行影像色彩品質的評估,在不同掃描速度之色差分析上得到極好的穩定結果。

Spectral imaging technology is gaining much attention in the academic development among many modern countries. Its advantage is to improve the color analysis capability of each image pixel by recording more the R, G, B signals commonly seen in digital camera. The spectral reflectance characteristics of the object is recorded. However, how accurate is the spectral signals? This research explores the stability of a multi-spectral imaging system while using different scanning speed. The results will provide a good reference for multispectral imaging.
