摘　　要：实时图的仿真生成是景像匹配仿真研究中的重要内容之一。系统研究了实时图仿真中的各种畸变模型的建立问题。分析了实时图与基准图之间存在的主要差异,设计了包括噪声干扰、几何畸变、灰度畸变等形式的十种畸变模型,给出了相应的实验结果。通过匹配仿真实验验证了这些模型在匹配算法性能评估及基准图可匹配性检验中的实用意义。Simulation production of real-time image is very significance to the research of scene matching simulation.The problem of distortion model establishment for real-time image simulation is systematically studied in this paper.The main difference between the real-time image and the reference image is analyzed, 10 distortion model including noise disturbance,geo- metric distortion,grayscale distortion,and so on styles are designed,meanwhile,the corresponding experimental results are given.Finally,the scene matching simulation indicates the practicability and efficiency of the distortion models,while it be used in the performance evaluation of matching algorithm and the matching ability test of reference image.
