- Testing: Evaluate the system's performance under various scenarios.

- Integration: Deploy the model into the simulation for autonomous navigation.

4. Technical Implementation

Step 1: Install Required Tools


# Example: Carla
pip install carla

# Example: DonkeyCar
pip install donkeycar

Step 2: Collect and Preprocess Data


# Use Carla to collect sensor data
import carla

client = carla.Client('localhost', 2000)
world = client.get_world()
blueprint_library = world.get_blueprint_library()
vehicle_bp = blueprint_library.filter('model3')[0]
spawn_point = world.get_map().get_spawn_points()[0]

vehicle = world.spawn_actor(vehicle_bp, spawn_point)
camera_bp = blueprint_library.find('sensor.camera.rgb')
camera = world.spawn_actor(camera_bp, carla.Transform(), attach_to=vehicle)

camera.listen(lambda image: image.save_to_disk('_out/%06d.png' % image.frame))

Step 3: Train the Perception Model


from tensorflow.keras.models import Sequential
from tensorflow.keras.layers import Conv2D, MaxPooling2D, Flatten, Dense

model = Sequential([
    Conv2D(32, (3, 3), activation='relu', input_shape=(128, 128, 3)),
    MaxPooling2D((2, 2)),
    Conv2D(64, (3, 3), activation='relu'),
    MaxPooling2D((2, 2)),
    Flatten(),
    Dense(128, activation='relu'),
    Dense(1, activation='sigmoid')  # For binary lane detection, modify as needed
])

model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])
model.fit(training_data, training_labels, epochs=10)

Step 4: Integrate Model with Simulation


# Example: Use trained model to predict lane directions
def control_vehicle(image):
    prediction = model.predict(image)
    # Use prediction to steer vehicle

5. Results and Insights
