Example Embodiment

[0030]下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。

[0031]本发明的目的是提供一种适用于隧道环境下的定位跟踪系统及方法，能够适应任意长度不规则形状的隧道。

[0032]为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。

[0033]图1为本发明所提供的一种适用于隧道环境下的定位跟踪系统结构示意图，如图1所示，本发明所提供的一种适用于隧道环境下的定位跟踪系统，包括：服务器、定位标签、多个定位基站以及多个球机；球机能够实现水平旋转360°，上下旋转90°。

[0034]所述定位标签设置成多种通信模式，用于与定位基站进行单工通信或者半双工通信。

[0035]所述服务器分别与多个定位基站以及多个球机连接；

[0036]所述定位基站均匀的设置在隧道一侧；在隧道另一侧，在与定位基站对应的位置，将定位基站和球机交替设置；

[0037]所述服务器可采用到达时间差法或飞行时间测距法确定定位标签的位置。所述服务器在采用到达时间差法时，根据定位标签的所在区域确定待同步的定位基站的IP以及待同步的同步基站的IP；所述服务器在采用飞行时间测距法时，根据定位标签的所在区域确定待通信的定位基站的IP；并利用粒子滤波算法得到定位标签的最优估计位置，进而将定位标签的最优估计位置发送至标签所在域的球机；所述球机根据定位标签的最优估计位置进行跟踪。

[0038]所述定位基站与所述定位标签的IP地址不同。

[0039]所述定位基站包块：第一天线、第一UWB接发模块以及第一时钟模块。利用第一UWB接发模块发送和接收时间戳；

[0040]所述定位标签包括：第二天线、第二UWB接发模块以及第二时钟模块。利用第二UWB接发模块发送和接收时间戳

[0041]本发明所提供的一种适用于隧道环境下的定位跟踪系统，还包括：交换机；

[0042]所述交换机用于将所述服务器与多个定位基站以及多个球机进行连接。

[0043]本发明的基于超宽带和视频联合的定位跟踪系统，并能够依据图1获得定位基站和球机准确位置坐标信息。服务器采集从定位基站的时间戳，定位算法得到当前时刻的量测位...

Abstract

The invention relates to a positioning and tracking system and method suitable for a tunnel environment. In the system, a positioning tag is set into different communication modes to realize simplex communication or half-duplex communication with a positioning base station; the positioning base stations are uniformly arranged on one side of the tunnel; on the other side of the tunnel, the positioning base stations and the ball machines are alternately arranged at the positions corresponding to the positioning base stations; the position of the positioning tag can be determined by adopting a time difference of arrival method or a time-of-flight ranging method; obtaining an optimal estimation position of the positioning tag by using a particle filtering algorithm; and the dome camera performs tracking according to the optimal estimation position. According to the invention, positioning and tracking of the tunnel with any length and irregular shape can be realized.
