## 2.2 SteamVR的配置
正常来说SteamVR的启动必须需要头显才能启动所以需要对SteamVR的部分配置文件进行修改以得到无头显启动的目的。
正常来说SteamVR的启动必须需要头显才能启动。所以采取的方式有两种第一种是绕过头盔启动。第二种方式是把控制器的虚拟为头盔。
#### 2.2.1 查看SteamVR的log
既然是设备是通过steamVR来驱动链接的那么在steamVR启动的时候肯定就要做设备初始化等等的工作那么设备加载初始化的时候到底是加载了那些文件了导致非要加载头显HMD。我们可以通过查看log来查看SteamVR到底加载了那些驱动和设置。查看log的方式如下图所示
<center>
<img src="./Image/SteamVR Log Setting.png" alt="image-20231130113103087" style="zoom:100%;" >
</center>
#### 2.2.2 配置文件的修改——绕过头盔启动
在找到SteamVR的log后(log文件`vrserver.txt`)我们可以对log进行分析
```shell
... [Settings] Load Default Json Settings from ...\common\SteamVR\drivers\htc\resources\settings\default.vrsettings
... [Settings] Load Default Json Settings from ...\common\SteamVR\drivers\lighthouse\resources\settings\default.vrsettings
... [Settings] Load Default Json Settings from ...\common\SteamVR\drivers\null\resources\settings\default.vrsettings
... [Settings] Load Default Json Settings from ...\common\SteamVR\resources\settings\default.vrsettings
... [Settings] Load Json Settings from C:\Program Files (x86)\Steam\config\steamvr.vrsettings
```
实际经过发现,**只需要修改2个文件就可以实现绕过头显启动分别为上面的第3和第4个文件**。
一般来说SteamVR的驱动路径为`C:\Program Files (x86)\Steam\steamapps\common\SteamVR`如果找不到也可以在Steam平台上找到SteamVR然后选择`右键->管理->浏览本地文件`。
找到并修改`Resource\Settings\default.vrsettings`:
```json
// requireHmd == false可以使得SteamVR面板的头盔图标亮起, 但是一会儿就处于休眠状态
"requireHmd" : false
// 强制驱动为null driver, null driver是steamvr的一个空驱动
"forcedDriver" : "null"
// 强制多个驱动估计是增加可以激活lighthouse的控制器
"activateMultipleDrivers" : true
```
找到`drivers\null\resources\settings\default.vrsettings`进行修改:
```json
{
"driver_null" : {
// 由false修改为ture
"enable" : true,
"serialNumber" : "Null Serial Number",
"modelNumber" : "Null Model Number",
"windowX" : 0,
"windowY" : 0,
"windowWidth" : 2160,
"windowHeight" : 1200,
"renderWidth" : 1512,
"renderHeight" : 1680,
"secondsFromVsyncToPhotons" : 0.01111111,
"displayFrequency" : 90.0
}
}
```
#### 2.2.3 配置文件的修改——控制器的虚拟为头盔
配置文件完整样例在:`Code\steamvr_config`下,下面是修改的原理介绍以及实际修改方法。
**要将控制器虚拟为头盔操作和2.2.2的配置一致,但是需要额外添加配置**。通过SteamVR的选项`菜单->设备->管理追踪器->管理定位器`即可看到控制器的ID信息。如下图所示本机的定位ID为LHR-FFA35F47
<center>
<img src="./Image/控制器ID查看.png" style="zoom: 100%;" >
</center>
对应的修改配置文件我们在配置文件接近结尾处添加Json的键值对`TrackingOverrides`, 将控制器的路径映射到头显。值得注意的是,控制器的路径和设备有关,需要根据实际设备的信息调整,不能盲目修改。
```json
{
// 上方省略
// 这个地方添加了追踪映射
"TrackingOverrides" : {
// 注意LHR-FFA35F47一般是控制器设备的信息根据实际设备进行填写
"/devices/htc/vive_trackerLHR-FFA35F47" : "/user/head"
},
// 以下不用修改
"version": "1",
"jsonid": "vrsettings"
}
```
## 三、问题和解决方案
### 3.1 此设备目前不在定位,请确认其在一个定位器的定位范围内。
上述问题在SteamVR的面板显示如下图所示。这种问题产生的原因是因为基站的位置放置错误。两个基站放置的太近了一般两个基站需要相距1米以上。
