彩色而非灰度的简单塔架捕获

Question

I'm in the process of learning pypylon. The following code is my first success at capturing an image and displaying it via PIL. All good, but for one thing: it is capturing in grayscale and I would like to be capturing in color. And the information I need is lost in the vast sea of documentation and classes.

I can see that they offer zillion color formats, and I don't care: I just need something that is color and will convert nicely to a PIL image. Can someone suggest a small modification to this program that would accomplish that? (And by the way, what does the 2000 parameter do?)

# minimal capture image and show on screen in PIL format
import pypylon.pylon as py
from PIL import Image

tlf = py.TlFactory.GetInstance()
camera = py.InstantCamera(tlf.CreateDevice(devices[0]))

camera.Open()
camera.StartGrabbing(1)
grab = camera.RetrieveResult(2000, py.TimeoutHandling_Return)
if grab.GrabSucceeded():
    img = grab.GetArray()  # format: numpy array
    print(f'Size of image: {img.shape}')
    image = Image.fromarray(img)
    image.show() 
camera.Close()

Answer 1

You should look at the following website: https://docs.baslerweb.com/pixel-format You need to use the command: camera.PixelFormat.SetValue(PixelFormat_BGR8);
