[Python知识库]Halcon Python接口使用步骤

????????个人是先接触Python,后接触Halcon的.

之前虽然python一直没有入门,不过浅尝了opencv-python,pillow,matplotlib等库.

其实是最早听说halcon的,一直觉得很牛逼,胆小没敢亵渎.

后来发现halcon20.11版本增加了python接口,才开始了尝试.

由于halcon联合python相关资料非常的少加上基础薄弱过程相对困难.

?接下来说一下使用步骤.

操作系统:win10 64位; halcon:20.11 python:3.8以及以上.我用的3.8.

操作系统和是64位python解释器也需要是64位才行.至于win7还是win10没多大关系.

?如果只使用python那么halcon也可以不装.

首先为python安装halcon支持.

pip install mvtec-halcon==20111

?下来新建一个文件夹,里面新建一个.py文件.将对应版本dll复制进来.

?如果安装了halcon20.11仅仅测试是不需要复制这些DLL的.

?下来测试一下能不能用.

import halcon as ha 
Image = ha.read_image('pcb')
Width, Height = ha.get_image_size(Image)
print(Width[0], Height[0])
WindowHandle = ha.open_window(0, 0, Width[0]/2, Height[0]/2,father_window=0,mode='visible',machine='')
gray = ha.rgb1_to_gray(Image)
thres = ha.threshold(gray, 100, 200)
ha.disp_obj(Image, WindowHandle)
ha.wait_seconds(2)
ha.clear_window(WindowHandle)
ha.disp_obj(thres, WindowHandle)
ha.wait_seconds(5)

?可以看到"pcb"显示两秒,二值后5秒结束.

如果没有安装halcon20.11需要将第二行稍做修改,先将图片复制到程序运行目录,在改第二行.

假设图片文件名为"lina.jpg".那么修改第二行:

Image = ha.read_image('lina.jpg')#'lina'也可以,可以不加后缀名.个人习惯加上.

好了看到很多帖子说:VSCode中不加wait_seconds函数显示窗口一闪而过,啥也看不到,在Python自己的IDLE里面显示窗口可以停留,原因暂时未知);;;经过多次实验加无意中发现解决的办法.

官方给了3个例子.
