Distance measurement

This is a simple distance measurement project using a ESPCAM and Arduino IDE.

Ball Tracking

This project uses OpenCV to track ball movement and measure the distance. The process for tracking is as follows:

• Convert color to HSV
• Create a pixel mask to identify the ball using upper and lower color bounds
• Erode and dilate the mask to reduce noise
• Indentify contours and draw a circle around the ball

Prerequisites

• Python 3
• OpenCV
• Arduino IDE
• ESPCAM

Setup

Script

To install the python libraries run this command:

python3 -m pip install -r requirements.txt
or
pip3 install -r requirements.txt

Arduino IDE

In order to install the ESPCAM library, you need to add the following URL to the Arduino IDE: http://arduino.esp8266.com/stable/package_esp8266com_index.json

Getting Started

Run the ball tracking script:

python3 main.py --video name_of_the_video.mp4
