What can you do with the camera module in Pygame?
This is just the most basic example. You can track multiple different colored blobs, find the outlines of objects, have collision detection between real life and in game objects, get the angle of an object to allow for even finer control, and more. Have fun!
What does query _ image ( ) do in Pygame?
Since get_image () is a blocking call that could take quite a bit of time on a slow camera, this example uses query_image () to see if the camera is ready. This allows you to separate the framerate of your game from that of your camera.
How does the move function in Pygame work?
This is shown in my example code here within the players move function: By moving the blitting coods of the camera the an opposite direction and at the same velocity of the player, it cancels out the momentum of the player object, and creates the illusion that the player is standing still while the game world moves around him/her/it.
What do you need to know about Pygame 1.9?
Pygame 1.9 comes with support for interfacing cameras, allowing you to capture still images, watch live streams, and do some simple computer vision. This tutorial will cover all of those use cases, providing code samples you can base your app or game on. You can refer to the reference documentation for the full API.
How to connect a USB camera to a RPI?
The configuration of such a camera is very simple. Just connect the USB camera to one of the USB ports of the RPi. After doing that, we can check whether the camera works well or not by capturing images using the “fswebcam” package. At first, we need to install that package using the following command: After that, we can use it to capture an image.
How is Pygame used in building surveillance system?
PyGame is used for accessing the camera and capturing images which are stored inside the SD card of RPi. A background model is created for the scene to discover the changes from the default state. A simple circuit, connected to the GPIO pins, lights a led as an indication of such states. Cover image by Ahmed Fawzy Gad.
