Hololens2和Vuforia连用之unity2019平台_hololens2 集成vuforia

 此平台的组合为：unity2019+vuforia9.8

建议用2020+vuforia10.2平台，不要用此平台。因当前最新的vuforia10.2不支持unity2019。可vuforia10.2确实是最好用的，包括比例设置和稳定性。

所以本文就大概写一下，详细的还是参看2020那篇。

1. Create a new Unity Project. 
2. Switch build platform to UWP.
3. Click the Player Settings -> XR Plugin Management, and install the latest XR Management package and enable the Windows Mixed Reality under Plug-in Providers.
4. Import MRTK and Vuforia 
   1. Download the *.unitypackage for the MRTK here. Select the Microsoft.MixedReality.Toolkit.Unity.Foundation. The other packages are optional.
   2. Download the *.unitypackage for the Vuforia Engine here. 
5. Go to Assets -> Import Package -> Custom Package and import the MRTK and Vuforia packages. 
6. In the File menu, select Build Settings.
7. Select Player Settings and expand the Publishing Settings section.
   • Under Capabilities ensure that Internet Client, WebCam, Microphone, and SpatialPerception are selected.
     NOTE: SpatialPerception should only be selected if you intend to use the Surface Observer API.
   • Under Supported Device Families, ensure that Holographic is selected. 
8. Expand the Resolution and Presentation section.
   • Disable Run in Background so that Vuforia pauses when the app is put into the background and can access the camera again when the app is resumed.
   • In the Default Orientation dropdown, ensure that Landscape Left is selected.
9. Close the Project Settings window.
10. Add the MRTK to each scene using Mixed Reality Toolkit > Add to Scene and Configure
11. In the MixedRealityToolkit GameObject, in each scene, set the configuration profile to the DefaultHoloLens2ConfigurationProfile.
12. Select the Main Camera found as a child of the MixedRealityPlaySpace GameObject and add the VuforiaBehaviour component to it.
13. Vuforia engine安装好的菜单位置

Vuforia engine版本安装后的确认 

Main camera方式 

Camera中Open Vuforia engine configuration 

 Vuforia上传image尺寸设置0.21

 Vuforia上传image成功后

Image target选择后的默认比例（不能改，width事关x，改此一个其它会立马自动全改的，为何我传的是0.21这里调入后确实0.3263，还不能改动，否则识别不正常，这样会影响我对最终位置关系的判断，这是我放弃此组合的原因。）Cube设置

 因比例连城的关系，方块眼镜中看到的实际大小为0.5*0.3263，位置关系不变，在纸张的表面。
