Hi,
I read about "Monthly Reco Usage" that A "reco" occurs when your app recognizes an image or object. Deployment plans include a certain number of recos per month of all users of your app. But I don't know it is offline reco or cloud-based reco?!
Our project doesn't use cloud service, but we want to remove the watermark. So, please tell us the best choice of plans for our project.
Thank you!
Hi,
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
