Step 1: Acquire a Jetson Nano Developer Kit

Purchase: (Step 1: Essential Hardware) .

Connect Peripherals

  • Monitor :
  • HDMI or DisplayPort: Ensure your monitor supports one of these input types and use the appropriate connecting cable.
  • Resolution: If targeting image processing tasks, choose a monitor capable of displaying images at a sufficient resolution.
  • Keyboard and Mouse:
  • USB Ports: Most standard USB keyboards and mice will be compatible.
  • Configuration: Be prepared for potential initial keyboard layout and input configuration steps later on.

Connect Power Supply

  • Locate Power Port:


  • Model Variations: The exact power connector varies between Jetson Nano module versions. Look for either a barrel jack connector or a micro-USB port. (Add a brief note or link indicating the different Jetson Nano module variations.)


  • Plug in: Ensure a secure connection between the power supply and the Jetson Nano's power port.


  • Power on: The Jetson Nano should boot up, signaled by LEDs lighting up and the initial display output on your monitor.


Initial Boot Up (without Network Connection)

  • Verification: The basic boot screen indicates the power supply and boot sequence are functioning as expected. Check the board LEDs refer to your Jetson Nano model's documentation for verification.


  • Network Connection Delay: This step simplifies the initial setup, reducing potential software-related conflicts.

Step 2: Connect Camera

Choose a USB camera from thecompatibility list.

Connect the camera to a USB port on the Jetson Nano.

Verify camera detection in the system settings.

Step 3: Software Installation

Optional

a. Install NVIDIA Jetpack SDK:

  • Download the Jetpack SDK from the NVIDIA website.
  • Select your Jetson Nano version and operating system.
  • Follow the detailed installation instructions.
  • Launch JetPack after installation and choose "Flash OS".

b. Prepare Micro-SD Card:

  • Flash the Micro-SD card with the Jetpack SDK.
  • Insert the Micro-SD card into the Jetson Nano.

c. Install OpenCV and TensorFlow:

3. Face Recognition Implementation:

a. Prepare Dataset:

  • Collect high-resolution images of various faces.
  • Store the images in a folder on the Jetson Nano.

b. Develop Script:

  • Implement a Python script using OpenCV for face recognition.
  • The script should:
  1. Load images.
  2. Preprocess images.
  3. Detect faces.
  4. Extract features.
  5. Compare features with a database.
  6. Output results.

c. Training and Evaluation:

  • Divide the dataset into training and testing sets.
  • Train a face recognition algorithm.
  • Evaluate the model's performance.

d. Optimization and Fine-tuning:

  • Optimize the script and algorithm.
  • Ensure the solution runs in real-time.

4. Integration and Deployment:

a. Develop User Interface:

  • Implement features like live camera capture and user management.

b. Create Package:

  • Package the software and resources into an installation package.
  • Create installation instructions and tutorials.
