【STM32MP135F-DK】5- Evaluation on artificial intelligence - object recognition [Copy link]

After having a basic understanding of openSTLinux, we found that this system can run some artificial intelligence applications. In this evaluation, we will evaluate the performance of this board in artificial intelligence. X-LINUX-AI is a free open source software package dedicated to AI. It is a complete ecosystem that allows developers using OpenSTLinux to create AI-based applications very easily. The following is the ecosystem of openSTLinux.

The following is the overall framework of X-LINUX-AI

Specifically, X-LINUX-AI is a software package that allows developers to easily run some AI applications on their systems, so we need to build the environment for this AI software package.

We first connect our development board to the router with an Ethernet cable and configure it with an IP address in the same network segment as the router, so that our development board can access the Internet. For information on setting up the network environment, you can read my third review.

We can ping Baidu to see if our environment is set up. After the network environment is set up, we can download the software package.

First execute the following command in the console to configure the AI OpenSTLinux package repository

cd /var/cache/apt/archives
wget http://extra.packages.openstlinux.st.com/AI/5.0/pool/config/a/apt-openstlinux-ai/apt-openstlinux-ai_1.0_armhf.deb
apt-get install ./apt-openstlinux-ai_1.0_armhf.deb
 apt-get update

Then install all the X-LINUX-AI packages, I have already installed them here

apt-get install packagegroup-x-linux-ai

Restart the demo launcher to update the system interface

 systemctl restart weston-graphical-session.service

At this point the AI environment has been installed.

We enter the following command in the terminal to see the version of the AI environment

x-linux-ai -v

At this point, our interface has several more AI examples, as shown below:

When we click the two arrows, the interface will jump to the next page. There are two examples of photo classification and object recognition. Let's install the camera and run the object recognition example.

It feels like the accuracy is not very high, and the frame rate shown next to it is not very high either.

However, for the 1GHZ mp135, it is still quite capable of running artificial intelligence applications, after all, it is an entry-level SOC chip.

Summary: stm32mp135 can run AI-related applications, but its performance is limited, and its accuracy and recognition speed are poor.

Does this require some learning? Nowadays, small supermarkets use image recognition for cashier weighing.

This speed is fast enough. 15fps is completely suitable for civilian use - this is how I understand it

Is this recognition offline or online? If it is online, the scope of application is not that large.

Offline, online related programs are not written yet, I still don't know how to do it for the time being, I still need to study

I always feel that the screen is stuck when recognizing, especially when I turn the direction

Yes, you still have to train the model yourself. I'll give you a lesson when I have time.

--After the installation, several new icons appeared, for target detection. I don’t know what each one is used for and what is the difference between them?
