 ## 地图拼接
 
-固定定位标签
\ No newline at end of file
+子地图最小部署单元以4个定位标签为一组（标签间的距离<20m），如使用环境面积较大，可以搭建多个子地图，将子地图拼接在一起，形成一个大地图。
+
+准备工作：
+* 固定标签6个
+* Dashboard软件
+
+## 一、打开标签电源，摆放标签
+
+以下摆放位置为例：
+3 10 7
+4 11 8
+
+### 1、先建立submap0
+3 10
+4 11
+
+### 2、然后建立 submap1
+10 7
+11 8
+
+
+## 二、进入dashboard
+
+### 1、建立submap0
+
+勾选并激活 标签3、4、10、11 
+
+![](./imgs/advanced1.png)
+
+标签的实际摆放位置：
+3 10
+4 11
+
+顺时针数的顺序是3->10->11>4>3，Dashboard中顺时针的是3->4->11->10->3，软件与实际环境不符，进行地图翻转操作。
+

+
+翻转后，确认无误，freeze submap锁定地图 
+

+
+### 2、建立submap1
+
+#### 1）点击 + ，新增submap1，此时地图中无标签
+
+![](./imgs/advanced4.png)
+
+#### 2）勾选并激活 标签7、8，7和8加入地图中
+
+![](./imgs/advanced5.png)
+
+#### 3）	分别右键选择10、11，选择 add to current submap
+
+![](./imgs/advanced6.png)
+
+![](./imgs/advanced7.png)
+
+待7、8、10、11都加入地图后，检查标签顺时针顺序
+Submap1：10->7->8->11->10
+10 7
+11 8
+
+![](./imgs/advanced8.png)
+
+软件是10->11->8->7->10，继续做翻转，freeze submap锁定submap1
+
+![](./imgs/advanced9.png)
+
+此时dashboard地图与目标地图一致，地图拼接完毕
+3 10 7
+4 11 8
