采用红外织网的室内定位技术

提出基于红外织网的室内定位技术，该技术通过使用多对红外发射器和红外接收器交叉组成的探测信号网来覆盖待测空间，而空间中的运动目标无须增加辅助设备，就可实现对其精确定位。经过验证，红外织网的探测距离最大可达30 m，定位误差在0.05 m以内，具有良好的稳定性。当待测空间改变时，与其他室内定位技术相比，该技术无须变动系统的原来结构和工作方式，用户可以根据室内空间的大小来配置红外接收器的数目，其定位精度仍保持良好，较灵活地实现了系统的可扩展性和易部署性。

Indoor object location technology using infrared weaving

We present a new indoor location technology based on infrared weaving.By employing pairs of infared transmitters and receivers weaving signal network to cover the target space,the approach can achieve accurate location.Moving objects need no auxiliary equipment.The maximum distance in infared weaving can reach 30m and the error is below 0.05m.And the system shows good stability.Compared with the other indoor location technologies,users are able to set up the number of infrared receivers without changing the previous structure and operating mode when locating changed space,and the location accuracy remains unchanged.The system shows good flexibility,high stability and nice adaptability.
