摘要
车辆载体的随机振动影响摄像系统的成像质量,后续系统诸如目标跟踪和侦察预警系统的精度和稳定性。通过分析随机振动的特点及其产生的原因,可知随机振动受路面不平度、车辆载体类型和载体运动速度等因素的影响。根据采集的实际动态图像序列,分析摄像系统在不同影响因素下随机振动的特点。实验结果表明,车辆载体运动引起的图像帧间模糊和帧内模糊必须分别进行处理,电子稳像系统和算法应根据具体应用场景和实际系统要求进行选取。
The random vibration of vehicular motion influence the imaging quality of camera system, accuracy and stability of follow-up system, such as target tracking and detected pre-warning system. Through analyzing the reason for random vibration production and its characteristics, the roughness, vehicular type and speed have influence on random vibration. In the light of captured dynamic image series, the imaging system＇s features in different influencing factors were analysed. The experiments indicated that intra-frame and inter-frame blur produced by vehicular motion must be coped with separately. Electronic image stabilization system and algorithm are supposed to be chosen basing on specific application scenes and actual system requirement.
