📝 Week 4 exercises

This week we will learn the basics of artificial intelligence. We will try to connect to the drone through our library, to retrieve coordinates where the AI recognizes a traffic cone and to retrieve a frame from the camera. This week will prepare you for the end assignments.

Exercise 4

In this exercise you have to get a picture from the drone AI through the API. The API is used to get the data from the AI on the raspberry pi. We created a library with all of the functions, so you can just import the library and use the functions. Follow these step to use the API.

Installing the library

First, you have to install the library from the command line, like this:

pip install connectionLibrary

Using the library

Now you can use the functions in the library, we made two different functions. We made a function to retrieve the coordinates on the camera. We also made a second function to get the frame from the camera, as a picture. first you have to import it, like this;

import connectionLibrary

Coordinates

library.getCoords()

This function returns the coordinates from the API. The API gets this data directly from the drone camera and the AI.

Frame

library.getFrame()

This function returns the frame from the video stream. It returns it as a picture, with this picture you can do what you want.
