Error "Bad Frame Quality"

I'm getting the error attached error using Vuforia. After less than a minute with the camera open using Cloud Recognition. You press ok and another one appears, and so on.

using Unity 2018.2.2 and 2018.2.5 as well.

This happened on all the devices we tried, Samsung S8, Moto G4 for example.

This is a log that repeats every frame:

09-03 14:07:13.287: E/Unity(27490): (Filename: ./Runtime/Export/Debug.bindings.h Line: 43)

09-03 14:07:13.391: E/Unity(27490): Cloud Reco - Update Error: UPDATE_ERROR_BAD_FRAME_QUALITY

09-03 14:07:13.391: E/Unity(27490): UPDATE ERROR BAD FRAME QUALITY

09-03 14:07:13.391: E/Unity(27490): Low-frame quality has been continuously observed.

09-03 14:07:13.391: E/Unity(27490): Error Event Received on Frame: 1437

 

Do you see this when you run the Cloud Sample scene in the Core Samples?

 

It happens on the Core Sample when using the targets that I'm getting the error with, not the sample targets.

 

Could you private message me your database's keys so that I can attempt to reproduce locally?

Hey, do you know which Unity version is completely stable with cloud recognition? I can downgrade to it, but I need this to work.

 

Apologies for the delayed response. I just tried the keys you sent me in your message with the Core Samples and had no issues at all. I did not receive the error message you had. I used Unity 2018.2.4f1 with Vuforia 7.2.23 if you'd like to give that combination a try.

Out of curiosity, do you have ARCore support installed on these phones/this project? This could potentially cause the issue you are seeing.

 

ARCore support you mean the libraries on Plugin/Android folder? I do have them there, because I want to use them.

 

The low quality message might be due to this. Vuforia 7.2 currently doesn't have ARCore 1.4 support and therefor does not have autofocus support while using ARCore. I'll do some testing to see if I can reproduce it this way.

In the meantime, could you do me a favor and try testing this on a device without ARCore support and see if you get the same results?

Additionally, ARCore 1.4 support will be included with Vuforia 7.5 which should be available within the week. With this version the issue you are facing here may no longer be present.

 

I have the same error using Unity 2018.2.12f1 and Vuforia 7.5.20 and running on a Samsung Galaxy S8.

I ran the Core Samples with Cloud Example, but change the database. On Editor still not working, but after deploying it is working fine, except about this error reported on first post.

By the last reply I imagine that ARCore is not an issue anymore because I'm using 7.5.20.

 

Hello @Leapmon ,

ARCore 1.4 is supported by Vuforia 7.5.20, but only if the updated ARCore library is installed on the target device and enabled in your project:

https://library.vuforia.com/content/vuforia-library/en/articles/Solution/arcore-with-vuforia.html

If this is still giving you an error, I suggest you verify it is set to continuous autofocus as this will give you the best results in a dynamic environment.

Thanks,
