This page describes the steps to implement a simple frame-grabber script.

** UPDATED for v2.x **

Table of Contents

Overview

The following paragraphs will go through the steps to implement and run a simple frame-grabber script.

We’ll make use of the ssh terminal to:

• create an python test.py file

• use nano to cut / paste a simple python code

• run the script on the MPCam

• view the result using a browser

For reference, the test code is available from github:

• https://github.com/siana-systems/mpcam-simple-demo

Steps

On your local host station:

• open an ssh session to:

  ssh mpcam@mpcam.local

• enter the default password: mpcam (for the mpcam user)

Create the test script

From the ssh terminal:

• create a remote test working folder:

  cd /data mkdir test cd test

• open an empty file:

  nano test.py

• cut / paste the following:

   

• save the file:

  • ctl + x

  • + Y

  • + [ENTER]

Run the test script

From your ssh terminal:

• run the python script

  After a few seconds, you should see in the terminal: >> start webcam server….
  
  

• open your browser on: http://mpcam.local:8080

  Open

  

  in the terminal, you should see: 192.168.1.21 - - [18/Jun/2021 22:03:08] "GET / HTTP/1.1" 200 -
  
  

• click on the “Webcam” link and it’ll open the frame-grabber streaming window:

  Open

  

Congratulation!

While you can develop on the MPCam with most typical Linux frameworks, we like to use Python for most CV & deep-learning tasks. To keep exploring, we recommend that you check out the following pages:

• Using VS Code for remote Python

• PyMPCam our thin module to access onboard features (buttons, IR LEDs, etc…)

• imutils on MPCam a forked imutils to provide convenient CV functions
