Pypyueye (stripped down)

Convenience wrapper around pyueye API for IDS uEye cameras.

This is a stripped down version of pypyueye by Gaby Launay, with no PyQt based GUI and its related threads. This version consists of a single file that you can easily drop in your codebase.

Pypyueye (stripped down) allows to easily manage an IDS uEye camera using higher level function than the ones provided by pyueye and the official ueye packages.

Installation

You have to install the IDS driver for the camera you intend to use. Then in your Python environment make sure you have installed the modules pyueye and numpy.

Usage

The following script allows to display the live video:

import cv2 # usign OpenCV to display the captured image
from pypyueye import Camera
from pyueye import ueye

with Camera(device_id=0, buffer_count=10) as cam:
    # setup the camera
    cam.set_colormode(ueye.IS_CM_BGR8_PACKED) # format for OpenCV
    cam.set_aoi(0, 0, 800, 600)
    print(f"INITIAL VALUES")
    print(f'fps: {cam.get_fps()}')
    print(f'Available fps range: {cam.get_fps_range()}')
    print(f'Pixelclock: {cam.get_pixelclock()}')
    cam.set_pixelclock(100)
    cam.set_fps(20)
    print("")
    print(f"MODIFIED VALUES")
    print(f'fps: {cam.get_fps()}')
    print(f'Available fps range: {cam.get_fps_range()}')
    print(f'Pixelclock: {cam.get_pixelclock()}')

    # start non-blocking live stream
    cam.capture_video(wait=False)
    
    while True:
        # capture a single frame
        frame = cam.get_frame()

        if frame is None:
            break

        cv2.imshow('Live Camera', frame)
    
        # press ESC to stop
        if cv2.waitKey(1) & 0xFF == 27:
            break
     
    # stop the live stream
    cam.stop_video()
