摘要
在分析国内外大间距轴线一致性检测方法的基础上,提出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。该方法任意选择远场中具有典型特征的景物作为非合作目标,利用不同光学传感器获取非合作目标图像,比较非合作目标在图像中的空间位置差异,进而得到轴线一致性检测结果。实验结果表明,该方法可满足大间距轴线一致性检测需求。将CCD成像系统夹持在被测对象机械轴线上,可实现机械轴线与光学传感器轴线间的一致性检测。该方法不受光学传感器工作波段限制,避免了其他检测方法体积重量大、对使用环境要求高等缺点,因此应用前景广阔。
Abstract
On the basis of analyzing the current methods for large spacing axes detection at home and abroad, a method of axial consistency detection based on non-cooperative target image processing technology is proposed, which selects scenes with typical features in far field as non-cooperative targets arbitrarily, utilizes different optical sensors to acquire non-cooperative target images, and obtains axial consistency detection results by comparing the spatial position differences of non-cooperative targets in images. Experimental results show that this method can meet requirement of large spacing axis consistency detection. While the CCD imaging system is reliably clamped on the mechanical axis of the target to be detected, the consistency detection between the mechanical axis and the optical sensor axis can also be achieved. This method is not limited by the optical sensor's working band and avoids the disadvantages of large volume, heavy carrying and high requirements on environment for other detection methods, so it has broad application prospects.
