Visualization of the Detection Results together with the Ground-truth

This Python script allows you to compare the detection results with the ground-truth (GT) by visualizing them side by side.

The source code of this sample can be found in <install-prefix>/share/metavision/sdk/ml/python_samples/vizu_gt_det when installing Metavision SDK from installer or packages. For other deployment methods, check the page Path of Samples.

Expected Output

A video which shows the detected Bbox and the labeled Bbox.

Setup & requirements

To run the script, you will need to provide the following input:

  • a recording file ( --record_file): an event-based input file in RAW or DAT format.

  • GT Bbox: a NPY file containing GT Bbox.

  • Detection Bbox: a NPY file containing detection Bbox.

Note:

  1. Both the GT and the detection Bbox should be encoded in EventBbox format.

  2. Type “q” to quit the simulated video.

How to start

To run the script on a RAW file:

python vizu_gt_det.py --record_file file.raw --gt /path/to/gt.npy --det /path/to/det.npy

To find the full list of options, run:

python vizu_gt_det.py -h
