Real time Computer vision with odroid

Unread post by ht_97 » Fri Jul 12, 2019 8:23 am

I'm doing a project on Computer vision for an autonomous pesticide sprayer. I'm using using a raspberry Pi 3b with a camera for detection of plants on which it needs to spray.
My first question is that, Is odroid XU4 or any other model a better alternative for my application?
If yes
1. Can it be done on OpenCV?
2. since i'm using simple relays and drivers for motor controlling. They require a 5v input signal as a high input. Can it also be done with the odroid?
3. if both 1 and 2 are possible, which os and libraries should i install and from where?

PS: Sorry if my questions seem stupid. I'm new to the whole engineering thing and this is my first somewhat big project.

Thanks in advance for your help

We are not familiar with OpenCV programming much.
But GPU accelerated OpenCL + OpenCV solution might be interesting. XU4 and N2 are supporting the OpenCL acceleration.

What is the computer vision for an autonomous pesticide sprayer??
It is difficult to know which hardware is suitable for which application.

Since XU4 voltage level is 1.8v, a level shifter like https://www.hardkernel.com/shop/xu4-shifter-shield/ is required. A voltage level of many other SoC is 3.3v, a level shifter is required anyway.

Motor drivers mostly use the PWM signal, so an I2C PWM controller may be needed.

If you are beginner, use OS used by many people like Ubuntu.
There are many ways to install each library, so it is difficult to answer how to install libraries.
