Why computer vision enables intelligent flight in Drone Programming - See It in Action

Why computer vision enables intelligent flight

📖 Scenario: You are programming a drone to fly safely and intelligently. The drone uses computer vision to see obstacles and decide where to go. This helps the drone avoid crashes and navigate well.

🎯 Goal: Build a simple program that uses a list of detected objects from the drone's camera and decides if the drone should stop or keep flying based on the distance to obstacles.

📋 What You'll Learn

Create a list called detected_objects with obstacle names and distances

Create a variable called safe_distance to set the minimum distance to obstacles

Use a for loop with variables obj and dist to check each detected object

Create a list called danger_objects with obstacles closer than safe_distance

Print the danger_objects list to show which obstacles are too close

💡 Why This Matters

🌍 Real World

Drones use computer vision to see their surroundings and avoid obstacles automatically, making flights safer and smarter.

💼 Career

Understanding how to process vision data and make decisions is key for drone programmers and robotics engineers.

1

Create the detected objects list

Create a list called detected_objects with these exact tuples: ("tree", 5), ("building", 12), ("bird", 3), ("pole", 7)

Drone Programming

# Create the detected_objects list with exact tuples
# Your code here

Need a hint?

Use square brackets [] to create a list and parentheses () for each tuple.

2

Set the safe distance

Create a variable called safe_distance and set it to 6

Drone Programming

detected_objects = [("tree", 5), ("building", 12), ("bird", 3), ("pole", 7)]
# Create safe_distance variable and set it to 6
# Your code here

Need a hint?

Just write safe_distance = 6 on a new line.

3

Find obstacles closer than safe distance

Create an empty list called danger_objects. Use a for loop with variables obj and dist to iterate over detected_objects. Inside the loop, if dist is less than safe_distance, add obj to danger_objects.

Drone Programming

detected_objects = [("tree", 5), ("building", 12), ("bird", 3), ("pole", 7)]
safe_distance = 6
# Create danger_objects list and add objects closer than safe_distance
# Your code here

Need a hint?

Remember to create an empty list first, then use a for loop to check each distance.

4

Print the danger objects

Write a print statement to display the danger_objects list.

Drone Programming

detected_objects = [("tree", 5), ("building", 12), ("bird", 3), ("pole", 7)]
safe_distance = 6
danger_objects = []
for obj, dist in detected_objects:
    if dist < safe_distance:
        danger_objects.append(obj)
# Print the danger_objects list
# Your code here

Need a hint?

Use print(danger_objects) to show the list.
