EasyAR Common Technical Problems

We often confront technical problems in EasyAR developing. Here I sum up problems encountered in AR developing.

1.Language Support in EasyAR Developing


(1)Set up camera

Camera Focus

3.Model shaking

First, your target texture must be complicated.

(1)Solution onerecreate an ARCamera to render the target, copy its position and angle to make Vector3.Slerp move slowly.

We will sum up solutions in a tutorial later.

4.Model displaying without targets


5.Screen-recording Project

EasyAR Developing Skills----Screenshot ----

7.SightPlus App Scanning for special effect

Our solution is to use Unity camera filter.

8.Targets tracked by EasyAR

EasyAR doesn’t limit targets tracking quantity. The quantity lies in hardware performance and target size in the scene. It can track over 10 targets in PC while in popular smart phones, it can track 4 to 6 targets. But we suggest not to track many targets, which will influence user’s experience.

9.iOS Run and EasyAR Scene Out

Add rights in info.plist


If you have any questions, leave your commets.

    Hi. I'm trying to build my Unity Project with EasyAR SDK for IOS. At first i had got black screen, but all targets was recognized. Then i had tryed the solution from FAQ with replacing AppController with but Xcode returns me an error:

    Undefined symbols for architecture arm64:
      "_MMTUnityRenderEvent", referenced from:
          _ezarUnityRenderEventMerge in EasyARAppController.o
      "_MMTUnitySetGraphicsDevice", referenced from:
          _ezarUnitySetGraphicsDeviceMerge in EasyARAppController.o
    ld: symbol(s) not found for architecture arm64
    clang: error: linker command failed with exit code 1 (use -v to see invocation)

    I also had included GameKit and some other frameworks in Unity EasyARAppController settings, but it didn't help.
    Maybe you can help me to solve this issue, or direct me where to dig?
    Great thanks.

    but the camera on the phone is all black. Help me please.

    Keto Fuel But you do not have 12 weeks to shed that final layer of frame fat this is stopping you from revealing the ones abdominals which you have labored so tough for in the health club every day.The answer for your fat loss prayers might also come in the shape of the CKD or Cyclical Ketogenic food regimen! Now even though this eating regimen has prolonged durations of "Low Carb" with quick periodic refeeds scheduled in, it in no manner is making an attempt to present the belief that carbs are terrible.

    Supreme Test X Consume healthier, exercise, drink masses of water and ensure that you burn extra energy than you're taking in normal.Please study that last declaration again as you could shed 52lbs of fat this yr with out even hitting the health club. While some of you may no longer want to lose that plenty weight I just need you to begin thinking on how this is even feasible.

    当未检测到摄像头时,应用出现卡死的现像,理论只应当出现“fail to build AR”而不应该卡死,望解决(优化)

    When the camera is not found, the application of stuck phenomenon, the should return "fail to build AR" and should not be stuck, hope to solve (or optimization)
