python 用pypylon如何实现同时调用三个巴斯勒摄像头

Question

请问python语言，用pypylon如何实现同时调用三个巴斯勒摄像头？

Answer 1

导入Pypylon库并创建Pylon.InstantCameraArray对象，该对象可以用于同时访问多个摄像头。

from pypylon import pylon

num_cameras = 3
cameras = pylon.InstantCameraArray(num_cameras)
for i, camera in enumerate(cameras):
    camera.Attach(pylon.TlFactory.GetInstance().CreateFirstDevice())
    camera.StartGrabbing()
    converter = pylon.ImageFormatConverter()
    converter.OutputPixelFormat = pylon.PixelType_BGR8packed
    while camera.IsGrabbing():
        grabResult = camera.RetrieveResult(5000, pylon.TimeoutHandling_ThrowException)
        if grabResult.GrabSucceeded():
            image = converter.Convert(grabResult)
            img = image.GetArray()
            # 处理图像
