大间距轴线一致性检测技术进展与分析
|
摘要
多光学传感器轴线一致性是确保武器系统光电任务设备正常工作的重要保证。分析了国内外大间距轴线一致性检测方法与设备研制现状,提出了一种基于非合作目标图像处理技术的轴线一致性检测方法。选择远场中具有典型特征的景物作为非合作目标,通过比较非合作目标在不同图像空间中的位置差异,得到轴线一致性检测结果。该方法避免了其它检测方法体积重量大、对使用环境要求高的缺点,特别适合于大间距平台光电装备野外在线轴线检测,应用前景广阔。
The axis consistency of multiple optical sensors is an important guarantee to ensure the normal operation for photoelectric task equipment of weapon system. The presented status quo of methods and equipment are analyzed for measuring the consistency of large spacing axes. An axis consistency detection method is proposed based on non-cooperative target image processing technology. Specifically, it is available to select scenes with typical characteristics in the far field as non-cooperative targets. Then, the axis consistency detection results are obtained by comparing the position differences of non-cooperative targets in different image spaces. Compared with other detection methods and equipment, our method avoids many disadvantages including huge volume, heavy weight and the limited operation environment. Furthermore, it is especially suitable for axis detection of in field and on-line to large-distance photoelectric equipment, which shows a bright application prospect.
