gaplan / deep-diver-following Goto Github PK

This is a container for an autonomous diver-following project. Deep object detection models are used for diver (and other objects such as ROV) detection. A simplified version of that is utilized for autonomous tracking (and following) of a single diver by an underwater robot. The ROS version, tested on Aqua-8 robot, is provided in the diver_following_cnn folder.

• Dataset information: https://onlinelibrary.wiley.com/doi/full/10.1002/rob.21837
• Frozen graph of a trained (SSD MobileNet) model: provided in model_data folder
• Weights for the CNN-based model proposed in the paper: available on request
• Important packages: Python 2.7, OpenCV 3, TensorFlow 1.11.0 (with object detection API)

Use the test_detector.py file for testing detection performances on individual images.

Single diver	Multiple divers	Divers and ROVs

For testing diver-tracking on a video or sequences of images, use the test_diver_tracker.py file. A couple of videos and image sequences are provided in the test_data folder. Change the argument values to test other files.
