基于LiDAR系统RCD105影像的匀光方法研究

Research on Dodging Methods of RCD105 Aerial Images in LiDAR System

针对机载激光雷达系统ALS50平台中RCD105影像特点,分析出该类影像的匀光重点。探讨了典型的匀光方法,分析了传统方法的优点与不足,提出了一种改进的匀光方法。通过实验,利用调制传递函数体系评价了不同方法处理前后的影像质量,证明了改进匀光方法的可行性与有效性。

According to the features of RCD105 images in ALS50-LiDAR system, we summed up the key point of dodging methods, discussed the typical method, and analyzed the advantages and disadvantages of traditional method in this paper.And then, we proposed an improved method. Finally, through the experiment, we used the MTF method to evaluate images' quality, and proved the feasibility and effectiveness of the improved method.
