摘要: 在三维多模式扫描近景测量系统中,使用彩色线阵CCD(电荷藕合器件)可得到景物的一维线状彩色信息,将连续获得的不同角度上的一维彩色图像拼接起来即可形成全景彩色图像。直接在电脑彩色CRT(cathode ray tube, 阴极射线管)显示器上输出该图像,将发生色度失真,需要进行色度校正。通过光谱法色度校正,使得在电脑彩色CRT显示器上输出的图像和原始景物尽可能地保持色度不失真。

Abstract:In the three dimensional multiple modalities scanning real scene measurement system, a color linear CCD was used to obtain the one dimensional linear color information of the scene. Successive one dimensional color images of different angles were patched to constitute the full view color image. If the color image is displayed directly on the color cathode ray tube (CRT) monitor of a computer, colorimetric distortion will occur. Colorimetric correction is then needed. Through the spectral colorimetric correction, the color image displayed on the color CRT monitor is mauched with the original scene in the colorimetric sense.
