Monthly Reco Usage

July 13, 2019 - 6:53pm #1

Hi, reading about the Basic+Cloud plan and its allowed usage of 10,000 reco's a month and then a charge of .01 per reco. 10,000 recos in an app with multiple targets and a decent userbase would be chewed up very fast i feel. What happens if you need 1,000,000 recos a month? That means a charge of $10,000 a month would be applicable which is not viable.

Can you use a localdatabase and increase the number of targets from the allowed 1000? I cannot see the benefit in using the cloud when the charges could be so high. Is a plan available with more Recos per month as i dont think any developer could risk being charged an unforseen amount of money.

Please advise.

Hello,

his 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:

Thanks,
