Python module bindings for SORT algorithm (Simple, Online, and Realtime Tracking) implemented in C++, with the goal of being fast and easy to use. Tracker is based on this repo.
Before you can install the package, you need to install the following dependencies:
$ sudo apt install libopencv-dev $ sudo apt install libeigen3-dev
Make sure pip is upgraded to last version:
$ pip install pip --upgrade
Then you can install the package using:
$ pip install sort-tracker
$ git clone https://github.com/MrGolden1/sort-python.git $ cd sort-python $ pip install .
import sort # Create a tracker with max_coast_cycles = 5 and min_hits = 3 # Default values are max_coast_cycles = 3 and min_hits = 1 tracker = sort.SORT(5,3)
Two main methods are available named
get_tracks and you can specify format of input and output bounding boxes as follows:
# format (int): # 0: [xmin, ymin, w, h] # 1: [xcenter, ycenter, w, h] # 2: [xmin, ymin, xmax, ymax]
defaulf format is 0.
run method takes an array of bounding boxes and format, and then performs tracking.
# Input: # bounding_boxes: a numpy array of bounding boxes [n, 4] # format: format of bounding boxes (int) import numpy as np bounding_boxes = np.array([[10, 10, 20, 20], [30, 30, 40, 40]]) tracker.run(bounding_boxes, 0)
get_tracks method returns a array of tracks.
# Input: # format: format of bounding boxes (int) # Output: # tracks: a numpy array of tracks [n, 5] where n is the number of tracks # and 5 is (id, ..., ..., ..., ...) where id is the track id and ... is the bounding box in the specified format tracks = tracker.get_tracks(0)
