摘要
多光谱遥感器彩色图像合成是直接提取多光谱图像中R、G、B 波段合成,由于多光谱成像探测器光谱响应特性与国际照明委员会(CIE)颜色匹配函数严重不匹配,合成的彩色图像出现严重的颜色失真,需进行颜色校正。针对目前传统的白平衡法和色度学合成法的不足,提出了基于发光二级管(LED)光谱可调积分球光源的多光谱相机多点改进型色度合成校正方法。该方法既考虑了地物的光谱特性而且实现简单。实验表明,采用白平衡法校正,目标色品误差最大为0.15,而采用该方法能够将目标色品误差限制在0.05 以内。
Abstract
Multi spectral remote sensor image synthesis is directly extracted from R, G, B bands of the multispectral images. Because of the mismatch between the spectral response characteristics of multi spectral imaging detector and international commission on illumination (CIE) color matching functions, color images appear serious color distortion. In order to correct the color distortion, color correction is needed. Aiming at the shortcoming of traditional white balance method and color synthesis method, improved multi point color synthesis method based on spectral tunable light emitting diode (LED) integrating sphere is proposed. This method not only contains the spectral features of the objects but also is easy to realize. It is proved that the color chromaticity error of the target can reach 0.15 corrected by white balance. However the color chromaticity error of the target can be limited less than 0.05 when the method is used to correct the color distortion.
