Overview

To track the targets, the Track framework requires some information about the target. The VIRNECT Track Target Trainer is a CLI application that generates this trackable data, which fuses the virtual and real objects.

CLI Trainer

Starting the trainer application with no argument, or -h, or -help displays usage instructions.

The following types of targets can be trained with our CLI Trainer application:

• Image targets
• QR Code targets
• CAD targets
• Shape targets

Info

Map targets need to be recorded with the framework itself. See: Map Target Recording.

File Format

All trained targets will be saved in the .track file format. Detail information about the content of a .track file can be extracted using the export function of the trainer:

Exporting detailed target information requires 3 arguments:

• -E to enable export mode
• Output directory
• Input .track target file

This exports the input file, embedded during target training, to the given output directory. It also provides detailed information about the .track file in the console:

• Target name
• Target type
• Target Version
• Internal ID
• Physical dimensions in meter
• Binary file size

Naming Conventions

• Ensure unique target names for all targets used in one application.
• Tracking different targets with the same name is not possible.

• The target name can only consist of the following characters:

  • a-z
  • A-Z
  • 0-9
  • _

• The generated .track file will have the target name as file name.

  Attention

  Do not rename the .track file. Otherwise it can not be loaded.
