uEye Industrial Camera

UEye Camera

This IDS imaging uEye camera can be controlled via USB communication.

Prerequisite

Please download and install the uEye camera software that installs the necessary drivers from IDS imaging.

You need to also install these python libraries.

pip install pyueye numpy opencv-python

Example

import cv2
from ueyewrapper import UeyeCam

def display_camera_output(camera):
    while True:
        camera.inquire_image_mem()
        frame = camera.get_image_data()
        cv2.imshow('uEye Camera (Press q to exit)', frame)
        if cv2.waitKey(1) & 0xFF == ord('q'):
            break

def main():
    # Initalize the camera
    camera = UeyeCam(device_id=0)
    camera.connect()
    # Set color mode
    camera.set_colormode(ueye.IS_CM_BGR8_PACKED)
    # Ret area of interest and allocate memory for acquisition
    camera.set_aoi(0, 0, 1280, 1080)
    camera.allocate_image_memory()
    # Capture video
    camera.capture_video(wait=True)

    # display video and exit when you press 'q'
    try:
        display_camera_output(camera)
    finally:
        camera.stop_video()
        camera.free_image_memory()
        camera.exit()
        cv2.destroyAllWindows()

if __name__ == "__main__":
    main()

This example code does the following:

1. Imports the necessary modules and the UeyeCam class from the ueye_cam.py file provided.
2. Defines a display_camera_output function that shows the camera output and allows the user to exit by pressing 'q'.
3. Defines a main function that:
   • Initializes the uEye camera with the given device ID (0 by default).
   • Connects to the camera.
   • Sets the color mode.
   • Sets the region of interest (ROI).
   • Allocates image memory.
   • Captures video.
   • Displays the camera output using the display_camera_output function.
   • Stops the video, frees image memory, exits the camera, and closes the display window after the user presses 'q'.

To run the example, make sure you have the ueye_cam.py file (the UeyeCam class implementation) in the same directory as the example script.
