Problem when create new area target of Vuforia Area Target Generator from LaserScan File

March 1, 2021 - 6:02pm #1

Currently, we using the newest vuforia area target generator application on window to generate a target from .E57 files.

We use the RTC 360 to create point cloud data, then use "Cyclone Register" to export .E57 file (All of this software already register license key). The total file size is around 9gb. When we import the .E57 file to "Area target generator" software and create area target, we have encounter a problem:

Hi @TRUONGKHANH

We just released 9.8.8 which should address the issue you faced.

Could you please give it a try?

Thank you.

You might run out of memory when using the ATG especially with bigger e57 files.

Could you please run it again and whatch out for ram usage? also could you please let us know how big the e57 file is.

Thank you.

Hello,

Thanks for your Reply! I had upgrade version similar yours Version Cyclone Register 2020.1. All of error have resolve. That is amazing.

But When file E57 load to Vuforia Area Generator (9.7.4), meet one problem (in attached image). I have found many Websites about Vuforia and Laser Scan, E57 file format... But I couldn't find any information. 

I notice the upgrade of Vuforia Area Target with Laser Scan file are really useful and potential. Near future, This application will be applicable to a lot of fields, especially the industry factory. 

Thanks for your support!

Hi,

[   FAIL  ] E57 shall contain one or more Image2D structures that have either 'sphericalRepresentation' field or 'pinholeRepresentation' field. indicates that the panoramas are missing. We believe the issue lies with the e57 scan exported from Lyca.

In this article we go over the steps necessary to transfer/ post process the scan: https://library.vuforia.com/area-targets/area-targets-leica-scans

Could you please review this steps for transfer and processing?

Also please make sure to use the cyclone REGISTER360 product and include the panoramas.

Thank you.
