全景相机与PTZ相机联动监控系统及位置关联模型

A COMBINED MONITORING SYSTEM AND POSITION CORRELATION MODEL OF CATADIOPTRIC CAMERA AND PTZ CAMERA

为实现大范围监视和指定区域精细观测与分析,提出一种全景相机与PTZ相机组合的联合监控系统。通过分析两相机安装的各种位置关系,建立起了统一位置关联模型。利用所建立的位置关联模型可方便地对监视场景的目标位置从全景图像到PTZ相机图像转换,为实现场景目标的联合监控奠定基础。实验结果表明,利用该模型所计算的水平、俯仰坐标相对于其实际测量值的平均误差均小于云台相机的实际控制误差,满足系统的联动控制要求。

In order to realize large-scale monitoring and fine observation and analysis in designated areas,a combined monitoring system including a catadioptric camera and a PTZ camera is proposed.By analyzing the various positions of the two cameras,a unified position correlation model was established.The established location correlation model could be used to convert the location of the target in the monitoring scene from the panoramic image to the PTZ camera image easily,which lays a foundation for the unified monitoring.The experiments show that the average errors of the Pan and the Tilt values calculated by our model are smaller than the minimum scale of spin in PTZ camera,satisfying the requirements of a coordinated control system.
