ACRV Robotic Vision Challenge 1 Evaluation Program

Evaluation code for the ACRV Robotic Vision Challenge 1, see https://competitions.codalab.org/competitions/20940

This is the code that will be used to evaluate all submissions. For the starter kit, see: https://github.com/jskinn/rvchallenge-starter-kit

For extra PDQ functionality including visualisation tools, extra evaluation measures, and COCO evaluation capability see: https://github.com/david2611/pdq_evaluation

Dependencies

The code is written using Python 3.5, and requires the following additional modules, installed using pip:

  • numpy
  • scipy
  • opencv

While not tested, it is also expected to work under python 2.7.

The docker image for all workers used to perform the evaluation can be found at https://hub.docker.com/r/jskinn/rvchallenge-codalab-worker/

Structure

This code is structured as a CodaLab scoring program.

To run code as done within codalab, run evaluate_codalab.py, which takes an input directory and output directory as command-line arguments. The input directory must contain a submission in a folder called 'res', which is read by the submission loader (submission_loader.py), and the ground truth information in a folder called 'ref', which is read by the ground truth loader (gt_loader.py). The resulting intermediate objects are defined in data_holders.py, and are passed to pdq.py to perform the evaluation.

Tests

Unit tests are contained in the tests subdirectory. Some of these tests (particularly the integration tests in test_integration.py) will fail to run without access to the ground truth.

Probability-Based Detection Quality

The key metric used for this challenge is the probability-based detection quality (PDQ) measure described in this paper: http://arxiv.org/abs/1811.10800, and explained in more detail on the competition page, here:

https://competitions.codalab.org/competitions/20940#learn_the_details-evaluation

This metric is implemented in pdq.py

Evaluating Results

Evaluating detections for a set of sequences can be done running evaluate.py.

This can be run from the command line with the following arguments:

--gt_folder - this is the directory which contains all ground-truth sub-folders to be evaluated against (one for each sequence).

--det_folder - this is the directory which contains all detection .json files to be evaluated (one for each sequence with filenames matching corresponding ground-truth sub-folder)

--save_folder - this is the directory where your final scores will be saved. If the folder does not already exist it shall be created.
