Setup

If you are interested in learning how our model was trained and want to try it training it yourself, you can follow these steps.

Prerequisites

Before you begin, you'll need the following:

  • A Snapchat mobile app and account.

  • Lens Studio - Download Lens Studio.

  • FFmpeg - Install FFmpeg. You can use homebrew to install it easily.

    brew install ffmpeg

Use Augmented Reality to generate the imageset

Download the sample Lens Studio project to record the videos we will use to train a custom model.

  1. Open up the sample project in Lens Studio.

Load Project

  1. Duplicate the symbols into 4 objects and place them around the scene.

Duplicate Symbols

  1. Pair your phone to Lens Studio with the Snapchat app and press the "Push Lens To Device" button.

Pair Phone

  1. With the Snapchat app, capture a few 10-second videos in different environments (grass, concrete, etc). You can scale up and down the symbols with "pinch-and-zoom."

  2. Download the videos to your computer and use FFmpeg commands to split the videos into frames. Depending on the length of your video, you will end up with around 100-200 images.

    ffmpeg -i [NAME_OF_YOUR_TRAINING_VIDEO.mp4] -vf fps=4 trainingvideo_out%d.jpg

  3. Next up, we will use the images to train our model.

Train the model

Follow the steps in this tutorial to create the model. Once finished, download the model_web folder to your computer.

Deploy the dashboard

Replace the the model_web folder in the tello-demo/public directory. Afterwards, follow the instructions here to test it out!
