    • A method for automatically estimating the spatial positions between cameras in a camera network utilizes unique identifying signals, such as RFID signals, transmitting between nearby cameras to estimate the relative distances or positions between cameras from received signal strength (RSS), time of arrival (TOA), or time difference of arrival (TDOA) measurements to thereby determine the neighboring relationship among the cameras. A discover-locate process can be used to discover, from the estimated relative distances, unknown cameras in the vicinity of at least three cameras at known locations. Absolute locations of the discovered unknown cameras can then be calculated using a geometric calculation. The discover-locate process can be cascaded throughout the network to discover and locate all unknown cameras automatically using previously discovered and located cameras. Such methods can be implemented in systems having cameras with transceivers integrated therein and a controller operably linked to the cameras.
    • 用于自动估计摄像机网络中的摄像机之间的空间位置的方法利用诸如RFID信号之类的唯一识别信号,在邻近摄像机之间传输,以从接收信号强度(RSS),到达时间(TOA)估计摄像机之间的相对距离或位置 )或到达时间差(TDOA)测量,从而确定相机之间的相邻关系。 可以使用发现定位过程从估计的相对距离中发现在已知位置处的至少三个相机附近的未知摄像机。 然后可以使用几何计算来计算发现的未知摄像机的绝对位置。 发现定位过程可以在整个网络中级联,以使用先前发现和定位的相机自动发现和定位所有未知摄像机。 这样的方法可以在具有集成有收发器的相机的系统中实现,以及可操作地连接到相机的控制器。
