Error in Area Target Generator

November 4, 2021 - 2:42am #1

Hi, 

 

We have a set of E57 scan data that I am trying to create an area target from using the windows tool but we are getting the following error.

Starting E57 processing "BEL-THER-PCS-GN-001_Structured.e57"

E57 processing: Validation of the E57 file failed. Check the validation report for details.

[ SUCCESS ] 'isColorInvalid' field in PointRecord structure must not be defined.

[   FAIL  ] E57 shall contain one or more Image2D structures that have either 'sphericalRepresentation' field or 'pinholeRepresentation' field.

[ SUCCESS ] 'pose' field in Image2D structure shall be defined.

[ SUCCESS ] Spherical images shall have minimal resolution of 4096x2048 and their width = 2 * height. Pinhole images shall have minimal resolution of 1024x1024 and must be square (width = height).

 

I am not sure on what scanner the E57 file is from. Does the Target generator only support the mentioned scanners on the developer page? My understanding was that the E57 file is a generic file and therfore it shouldn't matter?

 

Any help appreciated thanks

Hello,

It is correct that the Area Target Generator only supports the scanners listed here: https://library.vuforia.com/environments/area-targets

Unfortunately, E57 may be a generic format, but our experience is what is exported into those files by scanner OEMs can differ significantly. Thus, we have documented specific recipes and/or provide conversion scripts for each:

The Area Targets feature has specific export requirements, including including panoramic images.

Thanks,

Vuforia Engine Support
