电视经纬仪中的图像采集和序列图像中目标的自动检测定位是跟踪的关键。本文用VC平台设计实现了基于VFW的经纬仪图像采集系统,在自定义回调函数中对图像序列进行了实时处理。并根据跟踪气象用气球的应用要求设计了基于特征的目标自动检测算法。然后通过VC平台实现了算法的模拟实验。实验结果表明,本文算法可实现具有特定特征目标的自动检测,在此基础上分析了算法的优缺点,为以后的跟踪测量打下良好的基础。

Image acquisition and automatic detection of object in TV theodolite is the key to track of the object. This text use VC platform to design the image acquisition system based on VFW for TV theodolite,and process real-time picture array in self-defining callback function. Design the automatic detection algorithm based on the object＇s characteristic according to requirements of the application.Then realize the simulation experiment of the algorithm through VC platform. The experimental result indicates that the algorithm can realize the automatic detection of goal which have particular characteristics,and have analyzed the pluses and minuses of the algorithm and lay a good foundation for the later track of the goal.
