摘要
色彩处理是卫星影像处理应用过程中的重要环节,大区域的资源一号02C影像处理的难点在于真彩色模拟和色彩一致性处理。通过分析02C影像特点及大区域色彩处理的主要影响因素,提出基于最小二乘拟合的02C卫星影像真彩色合成方法和面向多时相大区域02C卫星影像的色彩一致性处理技术。在保证色彩真实的前提下,兼顾了大范围影像色彩的局部差异和合理过渡,从而使图面效果达到最佳。通过甘南地区的生产实验,表明提出的色彩处理技术的可靠性得到充分验证。
Color processing is an important part of the application process of satellite image processing.The difficulties of CBERS-1 02C image processing in large regions are true color simulation and processing of color consistency.This article proposes the true color synthesis method of 02C satellite image based on least square fitting and a processing technology of color consistency that serves for multi-temporal 02C satellite image in large regions by analyzing the 02C image characteristics and the main factors of color processing in large regions.By balancing the local difference with appropriate transition of image color while maintaining true color, the drawing effect reaches the best result.The reliability of color processing technology in this article is verified sufficiently by the production test in Gannan area.
