MaixPy Camera Usage

Introduction

For the MaixCAM, it comes with a pre-installed GC4653 camera, or an optional OS04A10 camera or global shutter camera, and even an HDMI to MIPI module, all of which can be directly used with simple API calls.

API Documentation

This article introduces common methods. For more API usage, refer to the documentation of the maix.camera module.

Camera Switching

Different cameras use different drivers, and the correct driver needs to be selected in the system.

TODO: How to switch between cameras, such as between GC4653 and OS04A10.

Getting Images from the Camera

Using MaixPy to easily get images:

from maix import camera

cam = camera.Camera(640, 480)

while 1:
    img = cam.read()
    print(img)

Here we import the camera module from the maix module, then create a Camera object, specifying the width and height of the image. Then, in a loop, we continuously read the images. The default output is in RGB format. If you need BGR format or other formats, please refer to the API documentation.

Skipping Initial Frames

During the brief initialization period of the camera, the image acquisition may not be stable, resulting in strange images. You can use the skip_frames function to skip the initial few frames:

cam = camera.Camera(640, 480)
cam.skip_frames(30)           # Skip the first 30 frames

Displaying Images

MaixPy provides the display module, which can conveniently display images:

from maix import camera, display

cam = camera.Camera(640, 480)
disp = display.Display()

while 1:
    img = cam.read()
    disp.show(img)
