1500 target images on a single database

September 28, 2019 - 12:29am #1

hello

We have a project in which 1500 target images should be identified. Is this possible with the free version of Vuforia license?

And is it basically possible to place 1500 target images on a single database?

Hi @sampro,

The Develop license aka the free one that you can create in the License Manager, should be used to prototype your application. If you want to commercialize the application/game you would need to purchase a paid license.

The topic of how many target images can be stored in a database is described here shortly: 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.

Not possible.
