Beginner - How to code Machine Vision and check on video? (Linux/Mac)

Question

Hi,

I would appreciate some help with getting my JeVois up and running so I can code my capstone project. I am interested in creating an algorithm that captures the face, saves and exports it so processing can be done on the iPhone app/Android.

I am struggling to access the "Coding IDE" on the JeVois. I have a VirtualBox with Ubuntu installed, but I can't seem to find where I can code and have the vision camera reflect my coding. Any help would be greatly appreciated!

Also, I have the microSD card with version 1, how do I upgrade my Jevois to 1.6?

Answer 1

The programmer tutorials here will take you through the process step by step:

http://jevois.org/tutorials/

There is no specific IDE for JeVois. You just edit source code files using your preferred IDE (either plain editor like emacs, or eclipse, etc) and then scripts are provided to compile C++ modules, flash them to microSD, etc

If you want to program in Python + OpenCV, you should indeed flash the latest microSD image to your SD card, and then check out this tutorial: http://jevois.org/tutorials/ProgrammerPythonLive.html

For C++, see that one: http://jevois.org/tutorials/ProgrammerSetup.html and then http://jevois.org/tutorials/ProgrammerHello.html

As part of the C++ build process, you will reflash your microSD card with the latest JeVois version from github and your new module.

Alright thank you!

I am currently stuck at trying to access the microSD card. I bought the JeVois with the microSD card having the software flashed, so I did not need to do that step.

But whenever I use the "jevois-usbsd start" command, I get errors. Currently, I am getting a "Timeout communicating with JeVois -- ABORT". I also receive "Cannot access /dev/ttyAMC0 -- is JeVois plugged in? -- ABORT". I am not sure how to proceed. I figured if I am able to access the microSD's contents, I can then program using Python and build my machine vision algorithm there.

Any ideas as to why these errors come up and how to fix them?
