基于CCD图像的空间目标识别技术

Space Target Recognition Technology Based on CCD Image

空间交会对接是空间机动技术的一个重要发展阶段。近距离对接需要对航天器进行精确识别。在此介绍了基于星载CCD图像的一种证据组合规则应用于序列图像目标识别算法。该算法以修正的Hu不变矩为图像特征,利用数据融合思想对来自目标的序列图像进行时间域融合处理。由BP神经网络对目标初步识别结果构造基本置信指派函数,用该组合规则进行决策级数据融合。

Rendezvous docking is an important stage in the space maneuver technology.A combination rule in evidence theory is introduced, which is applied to target recognition of sequential images.In this algorithm,modified Hu invariant moments is used as the feature of the image, and BP neural network is applied to identify the target.Then, basic belief assignment function is constructed through the output of the BP neural network, and afterwards the new combination rule is used to finish the decision data fusion.
