前言
对于早期的halcon版本，没有python接口，但是对于一些python爱好者来说，都想实现用python实现机器视觉的调用，用python结合halcon做一些功能，本文章会教你如何配置环境，后面会出一篇文章教你能从python+pyqt+halcon实现基本的定位功能。
一、环境配置以及代码实现
1.环境配置
pip install pythonnet
2.python文件中引入必要库
import clr
from time import sleep
clr.AddReference("HalconDotNet")
from HalconDotNet import *
这里就用python实现与dotnet的结合，因此可以使用from HalconDotNet import *
3.python+halcon代码
WindowHandle = None
AcqHandle = None
Image = None
Width = Height = None
AcqHandleHandle = HOperatorSet.OpenFramegrabber(HTuple("DirectShow"),HTuple(1),HTuple(1),HTuple(0),HTuple(0),HTuple(0),HTuple(0),HTuple('default'),HTuple(8),HTuple("gray"),HTuple(-1),HTuple('false'),HTuple('default'),HTuple('[0] '),HTuple(0),HTuple(-1),AcqHandle)
HOperatorSet.GrabImageStart(AcqHandleHandle,HTuple(-1))
Image = HOperatorSet.GrabImageAsync(Image,AcqHandleHandle,HTuple(-1))
(N,Width,Height) = HOperatorSet.GetImageSize(Image,Width,Height)
WindowHandle = HOperatorSet.OpenWindow(HTuple(0),HTuple(0),HTuple(Width),HTuple(Height),HTuple(0),HTuple('visible'),HTuple(''),WindowHandle)
while True:
Image = HOperatorSet.GrabImageAsync(Image, AcqHandleHandle, HTuple(-1))
HOperatorSet.DispImage(Image, WindowHandle)
HOperatorSet.CloseFramegrabber(AcqHandleHandle)
注意这的字符串，都必须要用HTuple()来引用，对于一些halcon算子的传出参数，可以先定义变量为None，然后即可实现参数的获取
二、本人测试接口的完整代码
import clr
from time import sleep
clr.AddReference("HalconDotNet")
from HalconDotNet import *
WindowHandle = None
AcqHandle = None
Image = None
Width = Height = None
# Image = HOperatorSet.ReadImage(Image,HTuple('fabrik'))
# (N,Width,Height) = HOperatorSet.GetImageSize(Image,Width,Height)
# WindowHandle = HOperatorSet.OpenWindow(HTuple(0),HTuple(0),HTuple(Width),HTuple(Height),HTuple(0),HTuple('visible'),HTuple(''),WindowHandle)
# HOperatorSet.DispImage(Image, WindowHandle)
# while True:
# pass
AcqHandleHandle = HOperatorSet.OpenFramegrabber(HTuple("DirectShow"),HTuple(1),HTuple(1),HTuple(0),HTuple(0),HTuple(0),HTuple(0),HTuple('default'),HTuple(8),HTuple("gray"),HTuple(-1),HTuple('false'),HTuple('default'),HTuple('[0] '),HTuple(0),HTuple(-1),AcqHandle)
HOperatorSet.GrabImageStart(AcqHandleHandle,HTuple(-1))
Image = HOperatorSet.GrabImageAsync(Image,AcqHandleHandle,HTuple(-1))
(N,Width,Height) = HOperatorSet.GetImageSize(Image,Width,Height)
WindowHandle = HOperatorSet.OpenWindow(HTuple(0),HTuple(0),HTuple(Width),HTuple(Height),HTuple(0),HTuple('visible'),HTuple(''),WindowHandle)
while True:
Image = HOperatorSet.GrabImageAsync(Image, AcqHandleHandle, HTuple(-1))
HOperatorSet.DispImage(Image, WindowHandle)
HOperatorSet.CloseFramegrabber(AcqHandleHandle)
# * Image Acquisition 01: Code generated by Image Acquisition 01
# open_framegrabber ('DirectShow', 1, 1, 0, 0, 0, 0, 'default', 8, 'rgb', -1, 'false', 'default', '[0] Integrated Camera', 0, -1, AcqHandle)
# grab_image_start (AcqHandle, -1)
# grab_image_async (Image, AcqHandle, -1)
# get_image_size (Image, Width, Height)
# open_window(0,0,400,-1,'root','visible','',WindowHandle)
# dev_open_window (0, 0, Width, Height, 'black', WindowHandle)
# while (true)
# grab_image_async (Image, AcqHandle, -1)
# dev_display(Image)
# * Image Acquisition 01: Do something
# endwhile
# close_framegrabber (AcqHandle)
总结
虽然此方法不是很好，效率相比C++和C#的调用可能不会很高，但是对于python爱好者来说这个就是一个比较好的实现方法，halcon新版本的已经支持python接口，所以本教程是对于低版本的halcon，我这里测试用的是halcon12版本64位
