摘要

分析研究了空中侦察序列图像连续拼接产生误差的原因，连续拼接中的误差累积与传播往往导致拼接图像质量难以接受甚至拼接过程失败，而拼接获取大视野战场毁伤全景图像具有重要军事应用价值；针对空中飘弋平台运动姿态复杂，成像模型难以建立的特点，提出了一种在连续拼接过程中变换基准图的拼接策略以消除累积误差的产生，通过对空中飘弋平台实拍序列图像和模拟仿真的序列图像进行拼接的实验结果表明，基准图的变换可大大减弱拼接过程中的累计误差影响，同时多次变换也会造成局部边缘的失真，但不影响后续的处理和使用，该策略的提出可为类似视点变化复杂的成像拼接提供误差消除方法和有效手段。

Abstract

In this paper we analyzed and researched the cause of the error during the aerial detection sequence continuous image stitching.The stitching of large visual battlefield damage panoramic image is important in military

but the accumulation of the error usually results in awful image quality or stitching process’s failure.Aiming at the character of complicated movement pose of floating aerial platform and the difficulties to establishing imaging model

in the paper presents a method which can avoid accumulated errors by transforming the base image in the continuous stitching process.The experiment with the floating aerial platform real time serial images and the simulated serial images proves that the transform of base image can obviously weaken the accumulation of error in stitching

and repetitious transform can induce the local edge’s distortion

but it does not have infection to the past processing and application.We present an effective method to avoid errors in image stitching under the situations like complicated vision transform.
