Jetson Xavier NX Lesson 15: Training the Face Recognition Program to Recognize People

In this video lesson we should you a simple method to train our face recognizer on larger data sets. We use the python os.walk command to step through, and train automatically on all the training images in our folder. We then show how to store our training set to our SD card using the pickle utility. This allows us to train once, and use the trained model over and over.

For your convenience, the code below is what we developed to allow training our face recognition model.

Then this is a simple program that loads the trained model, and uses it to recognize people in unknown images.


Robotics Training LESSON 11: Controlling the Elegoo Smart Car With IR Remote

In this lesson we show how you can control a robot with an IR remote. We program the Elegoo Smart Car version 3.0 to respond to  commands to the remote to go forward, backward, left and right.


Jetson Xavier NX Lesson 14: Face Recognition and Identification on NVIDIA Xavier NX

In this video lesson we show you how to train the NVIDIA Jetson Xavier NX to recognize faces, and then demonstrate finding those faces in a new unknown image.  We show step by step instruction in this easy to follow tutorial. We develop two python programs. The first one simply finds the faces in an unknown image, and the second program actually identifies the known faces. For your convenience, the code is included below.

Simple face detection Python code:

This next python program will learn faces, and then recognize them in new images.


Robotics Training LESSON 10: Using the Infrared (IR) Remote to Control Robot

In this lesson we show how to use the IR remote in the Elegoo Smart Car to send signals to the robot. The IR remote sends IR signals to the IR detector on the Electronic Shield sitting on top of the Smart Car. In this lesson we show how to install the IR library, and how to write code to send and detect IR signals. The code we develop in today’s lesson is included below for your convenience.
