Experiment with a color detection algorithm using Model Composer

4 Sep 2019

A couple months back, I decided to buy an Avnet Ultra96 V2 board and make something interesting. The Ultra96 is a compact, inexpensive platform with some amazing capabilities.

I decided to use a tool called Model Composer which allowed me to work with an example application, simulate it and verify performance all within an easy-to-use graphical environment. I did this mostly to learn all the individual steps myself.

I keep reading about self driving cars so I picked a color detection example that processes streaming input data and detects street signs. To show just how easy it is to work with Model Composer and target an Avnet Ultra96 board, I made a 4-part video series.

After going through some of the documentation, I was able to get my system working and picking out road signs with good repeatability. Of course, the output from this project is a functional block that is running on Ultra96 hardware. In a real-world system I would need to by a camera and a display too.

Nonetheless, it was an interesting project and I look forward to doing more work with image processing.

Hi Clem, I think for $250 the Avnet Ultra96 board is pretty good. It has all the basics and some good interfaces for various IoT things and artificial Intelligence. Plus and there are a lot of helpful…

I have a Honda Insight that uses a camera to get speed signs. But once in a while it gets odd numbers or picks up the sign on the high speed toll lane. I will have to investigate this. How do you like your Avnet Ultra96 V2 board jpitrus ?
Thanks for the blog,
Clem
