ADSN多传感器定位的古民居自动绘图体系

ADSN Multi-Sensor for Positioning to Automatic Plotting System of the Ancient Dwellings

便携快捷的无损绘图是ADSN(Ancient Dwellings Sensor Network)的重要功能.通过ADSN携带定位传感器与节点通信RSSI功能,完成对不同角色节点之间精确定位与测距,形成距离可知的拓扑.RSSI信号散度测距与红外传感器的点到点精度定位校正近距离RSSI精度,与远程超声点对点精确测距形成远程RSSI校正,通过测距拟合使得RSSI测距在50米范围达到10CM的精度.通过部署功能性节点(ID)完成对民居的功能性区域采样,形成对不同功能区域定位;形成拓扑后,使用标准功能图样库进行匹配与修正,完成对古民居的实景绘图.实际应用证明了方法的实用性.

Portable and efficient lossless drawing is an important function of the ADSN(Ancient Dwellings Sensor Network). Through the function of the ADSN localization sensor with node communication RSSI to complete the accurate positioning and ranging between the different roles to form a topology which distance can get to know. Using the RSSI signal divergence ranging and the point-to-point precision positioning of the infrared sensor to correct the RSSI's accuracy of the close range, and with remote ultrasonic point-to-point precision ranging to form a remote RSSI correction together, make the accuracy reach to 10 cm in the range of 50 meters by the range fitting. deploy functional nodes(ID) to corresponding functional areas of residential sampling, define different functional areas; the topology formation, using the standard functions pattern library to matching, complete the real drawing of the ancient dwellings. The practical application proven the usefulness of this method.
