Exporting Metadata from existing .track files

Exporting basic metadata

The trainer has a built-in utility function to inspect an existing .track file, and extract some metadata from it. This can be helpful to identify .track files.

The properties that are extracted for all files are:

• Name of the target
• Target type of the target (such as Object3D)
• Physical dimensions of the target

Exporting an image of the target

Optionally, by providing the --output command-line argument, an image of the target can be extracted. The exact relation of the image to the target depends on the target type:

• For Image targets, the fixed-resolution grayscale version of the training image is extracted
• For QR Code targets, the QR code image is extracted
• For Shape targets, a camera view of the target is extracted
• For CAD targets, this function is not supported

Usage
