Development

Activate the environment:

camera

Python serialization and deserialization for Autonomy.

Testing:

Attach a camera, then test the software:

Every nth image is saved as image0.png , image1.png , etc. They can be deleted after the test.

kml

Camera to QR integration:

Attach a camera and prepare a QR code to be shown, then test the software:

The text output should be as expected.

image_encoding

Encode and decode images from numpy array to jpeg (raw bytes). See Profile Encode Repository and Formats for more details on why jpeg was chosen.

Testing:

There will be a result.jpg in the image_encode directory after the test to ensure that the images look similar.

network

TCP and UDP socket tools to send data across a network (private networks).

Testing:

Unit test:

Integration test with image_encoding:
