How to Use Color Tracker for Multi Object Tracking

If you are looking for a simple and intuitive way to track multiple objects based on their colors, look no further than the Color Tracker. This Python package is designed with ease of use in mind and can significantly speed up your object tracking processes. In this guide, we’ll walk you through the installation, configuration, and troubleshooting steps necessary for effectively using the Color Tracker.

Installation of Color Tracker

To get started with the Color Tracker, you need to install it. The installation process is quite simple; just enter the following command in your terminal:

pip install color-tracker

If you want the latest version directly from the GitHub repository, you can use this command:

pip install git+https://github.com/gaborvecsei/Color-Tracker.git

Tracking Objects with Color Tracker

The Color Tracker can track red-ish objects by default. However, if you wish to monitor different colors, a customizable approach is at your fingertips using the hsv_color_detector.py script. Here’s how you can run the sample tracking app:

python examples/tracking.py --help

This command will display options for setting low and high HSV values, which you can tweak according to the color you want to track:

• -low LOW LOW LOW: Sets lower HSV range (default 155, 103, 82).
• -high HIGH HIGH HIGH: Sets upper HSV range (default 178, 255, 255).
• -c CONTOUR_AREA: Minimum contour area for object detection (default 2500).
• -v, –verbose: Enables verbose output.

How the Code Works: An Analogy

Imagine you’re baking a cake, and you need specific ingredients to get the perfect flavor. Here, our cake is the object tracker, and the ingredients are the parameters we use to tell the tracker what to look for.

In the Python script you would write, you first define how many cakes (or objects) you wish to track, just like how you would decide how many cakes you’re baking. Then, you gather your ingredients (i.e., color values) and input them so that the cake can taste just right.

As we bake, we keep an eye on our cake to ensure that it rises just as we like. In coding terms, this is akin to setting a callback function to display the debugging frame. Finally, just like we put the cake in the oven at the right temperature, you ensure that the camera captures the right lighting conditions for tracking.

Using the HSV Color Detector

One fantastic tool included in Color Tracker is the HSV Color Detector, which aids in identifying the proper HSV values for any color you’d like to monitor. This can be executed easily with the command:

python examples/hsv_color_detector.py

Troubleshooting Common Issues

While using the Color Tracker, you may encounter a few issues. Here are some common problems and their solutions:

• If your colors are not being tracked accurately, make sure to adjust your HSV range values. You may need to tweak them to fit the lighting and colors in your environment.
• If the tracker is not detecting objects consistently, consider increasing the contour area parameter. This ensures that smaller objects are filtered out for better tracking.
• In case of unexpected crashes or bugs, ensure that your Python version is compatible with the package. This package works best with Python 3.
