Device Database Info & Reco Limit

December 5, 2019 - 10:43pm #1

Hi,

 

I am creating an app where i am creating 100 device database

each database contain 200 images

so total 200x100 = 20000 images

When my app user scan, we check in only 1 database at a time based on user selection out of 100 database (it means at a particular point only single database of 200 images load)

So i am planning to go for Basic Plan

My queries:

1. is there any limit on database creation in single Basic Plan account

2. Is there any reco limit on device database as device database work on smartphone itself. I mean in basic plan unlimited user can scan unlimited times in our databases.

3. Is there any plan where we can pay monthly instead of complete year

 

Looking for your response

 

Regards

Sachin

Hi,

Please take the unlimited part with a grain of salt. I am not aware of any limitation however creating unlimited is definitely not possible/feasible.

In regards to your second question, Yes, app downloads are not a criteria for the Basic License.

Coming to your third questions, No, image search uses the device resources.

FYI- I deleted the duplicate post regarding the same issue.

Thank you.

Hi,

Answers below

1. No

2. No

3. Unfortuantely I am not aware of this possibility, please reach out to our Sales Department/ Billing department. https://engine.vuforia.com/contact/contact-sales or https://developer.vuforia.com/support/contact/billing

In regards to the number of databases, please review below:

This topic is briefly touched on in the following article: https://library.vuforia.com/articles/Solution/How-To-Work-with-Device-Databases.html

Vuforia's recommendation is a maximum of 1000 Image Targets in a single device database. However, there is no hard limit to the number that can be included.

That being said, you should be mindful of the amount of memory and CPU that your application will use when loading a large device databases. Vuforia adds each target in the device database to a dynamic search tree in your app's memory. Dynamic loading and unloading of device databases can be utilized to optimize memory usage (see DataSet APIs below). This technique can also help with CPU utilization during detection and tracking as Vuforia will require additional processing when attempting to detect large numbers of Image Targets in each camera frame. This is especially true for target detection, which is more CPU intensive than tracking.

Here are pointers to the DataSet APIs:

https://library.vuforia.com/content/vuforia-library/en/reference/cpp/classVuforia_1_1DataSet.html

https://library.vuforia.com/content/vuforia-library/en/reference/java/classcom_1_1vuforia_1_1DataSet.html

https://library.vuforia.com/content/vuforia-library/en/reference/unity/classVuforia_1_1DataSet.html

If you are attempting to utilize more than 1000 trackables, then we normally recommend our CloudReco products: https://library.vuforia.com/content/vuforia-library/en/articles/Training/Cloud-Recognition-Guide.html. There are two 'flavors': SDK APIs and Web APIs. Upon successful recognition, SDK APIs will return a single Image Target trackable (based upon the closest match) for 6DoF tracking experiences. Web APIs will return a prioritized list of target IDs, in match confidence order, but do not support 6DoF tracking experiences.

Thank you.
