在我的python项目中,我使用了baslergigevision以太网摄像头,因为pylon不支持python,所以我使用pypylon.pylon wrapper在python中打开它。这是我用来打开相机的类,但是在制作了可执行文件之后,我在打开它时会出错。I used spec file to work with pyinstaller.我得到以下错误:
import pypylon.pylon as py
import numpy as np
class PylonVideoReader:
def __init__(self, deviceName=None):
self.deviceName = deviceName
tlfactory = py.TlFactory.GetInstance()
if not self.deviceName is None:
deviceInfoList = tlfactory.EnumerateDevices()
deviceIndex = None
for i in range(len(deviceInfoList)):
if self.deviceName == deviceInfoList[i].GetUserDefinedName():
deviceIndex = i
break
if deviceIndex is None:
print("Device: {} not found please ensure that it is "
"connected".format(self.deviceName))
exit()
else:
# Create new camera
self.camera = py.InstantCamera(tlfactory.CreateDevice(
deviceInfoList[deviceIndex]))
else:
# Create new camera
self.camera = py.InstantCamera(tlfactory.CreateFirstDevice())
# Open camera
self.camera.Open()
# Set max number of frame buffers
self.camera.MaxNumBuffer = 50
# Initialize the image format converter
self.formatConverter = py.ImageFormatConverter()
# Set output pixel format to BGR8 for opencv
self.formatConverter.OutputPixelFormat = py.PixelType_BGR8packed
# Start grabbing process
self.camera.StartGrabbing(py.GrabStrategy_LatestImageOnly)
# Grab a first image to get its size
grabResult = self.camera.RetrieveResult(10000)
# Stop grabbing process
# self.camera.StopGrabbing()
# Get dimensions of image
self.frameWidth = grabResult.GetWidth()
self.frameHeight = grabResult.GetHeight()
def get(self, code):
if code == 3:
return self.frameWidth
elif code == 4:
return self.frameHeight
else:
print("{} is not a known property code".format(code))
def read(self):
# try:
# Start grabing process
# self.camera.StartGrabbing(py.GrabStrategy_LatestImageOnly)
# Grab an image
grabResult = self.camera.RetrieveResult(10000)
# Stop grabing process
# self.camera.StopGrabbing()
# Get dimensions of image
self.frameWidth = grabResult.GetWidth()
self.frameHeight = grabResult.GetHeight()
if grabResult.GrabSucceeded():
# Convert Grab result from YUV422 to BGR8
pylonImage = self.formatConverter.Convert(grabResult)
# Convert pylon image to opencv image
# image = np.frombuffer(bytearray(pylonImage.GetBuffer()), np.uint8)
image = np.asarray(bytearray(pylonImage.GetBuffer()), np.uint8)
image = image.reshape(self.frameHeight, self.frameWidth, 3)
return (True, image)
# except :
return (False, None)
def release(self):
self.camera.StopGrabbing()
self.camera.Close()

使用pyinstaller(How to make executable file with pyinstaller)生成可执行文件后,您应该从项目中使用的虚拟环境中找到pypylon文件夹,并复制exe文件旁边的pypylon文件夹。在
我可以通过以下步骤来解决这个问题,有些步骤可能不需要,但是到目前为止,这在我的案例中已经起到了作用。我发现this github issue很有帮助,使我走上正轨。在
首先,在我的脚本中过度导入:
我建议您不要在您的示例中导入pypylon的方式,将包简单地称为“py”会使其他开发人员感到困惑。在
接下来,我修改了规范文件的}。我将所有的pylon dll和pyd文件添加到
^{pr2}$binaries
、pathex
和{binaries
,将pypylon目录附加到pathex
,并将所有的可能性添加到hiddenimports
:我不确定所有这些都是绝对必要的,但是对于python3.4、pyinstaller3.3和pypylon1.3.1来说,这一切都是可行的。在
祝你好运!在
