不花冤枉钱!免VR头显使用Vive追踪器教程
上周,VR之家曾报道HTC员工在Reddit论坛上表示使用Vive追踪器必须搭配Vive VR头显。这就令部分打算在VR之外的场景使用这个追踪器的玩家感到头疼了,因为Vive头显可比追踪器贵得多了!但实际上,这所谓必须要使用头显只是软件层面不支持单独使用追踪器,并不是这套装置天生无法独立运行。所以,很快就有大神放出了这个免头显使用Vive追踪器的教程。
Valve开发的SteamVR追踪系统虽然是为虚拟现实准备的,但其应用场景绝不只是VR环境。对于开发者、极客、研究人员而言,这套系统带来了廉价、高精度、低延迟的位置追踪系统,而使用HTC新发售的Vive追踪器更是非常方便。我们拒绝仅为了使用单个售价99美元的追踪器而去购买800美元的Vive头显。
Triad半导体曾与Valve合作开发了光电转换IC芯片——TS3633,这款IC应用在SteamVR追踪系统中。供职于Triad半导体北极VR实验室(又名格林湾实验室)的Luke Beno就自行解决了Vive追踪器独立使用的问题。他擅长Python语言,并时常在办公室鼓捣3D打印。
这位极客现在提供了一份指导,帮助人们以最低花费使用SteamVR的追踪系统(235美元)。本指导书使用最新版SteamVR Beta版搭配python 3.6,pyopenvr库和triad_openvr实现。
最低硬件需求(网站后台不支持Markdown,排版可能不够清楚,请见谅):
*一个HTC Vive追踪基站(当然,两个更好)
*如下SteamVR兼容追踪设备(至少有一个):
*Vive追踪器(HTC无线适配器或USB)
*Vive控制器(Steam无线适配器或USB)
*使用SteamVR HDK开发的第三方追踪设备(Steam无线适配器或USB)
*x86 PC一台
软件需求(注意:仅在Windows上测试过,但估计也支持Linux):
*SteamVR软件Beta版
*Python 3.6(推荐Anaconda包)
*pyopenvr,安装命令:pip install pyopenvr
*triad_openvr,请从GitHub中下载(后台自动屏蔽超链接,用关键词在GitHub搜索)
1.下载并安装上述组件
2.定位如下配置文件,用任意文本编辑器打开:[Steam Directory]steamappscommonSteamVRresourcessettingsdefault.vrsettings
3.文本中定位“steamvr”下的“requireHmd”项,将值改为“false”。如图:
4.如果SteamVR正在运行,关闭并重启
5.当SteamVR重启之后,我们会发现现在可以在没有VR头显的情况下连接控制器或者追踪器了(注意:如果出现“Not Ready”字样,请忽略,不会影响这个教程的实施)
6.打开命令提示符,进入triad_openvr解压目录
7.如果你测试的是Vive追踪器,运行脚本:python tracker_test.py
8.如果你测试的是Vive控制器,运行脚本:python controller_text.py
9.脚本执行之后,我们能看到以250Hz频率更新的数字,这些是位置追踪的实时坐标
需要注意的是,本教程只是提供了一个快速的概念验证,证明SteamVR追踪系统并不需要VR头显。
最后,推广一下Python语言,Python是一个扩展性极佳的脚本语言,语法接近自然语言,非常容易理解。本教程中的代码今后也许会成为很多衍生项目的基础内容。这一方法也很容易改编成其他语言版本,例如C,C++或C#。
