Haclon +c# 实时图像显示

#Haclon +c# 实时图像显示| 来源: 网络整理| 查看: 265

首先第一步用Haclon软件写好实时采集代码：

* Image Acquisition 01: Code generated by Image Acquisition 01 open_framegrabber ('GigEVision2', 0, 0, 0, 0, 0, 0, 'progressive', -1, 'default', -1, 'false', 'default', '000f314ccf51_AlliedVisionTechnologies_Manta_G125BE0020002', 0, -1, AcqHandle) *打开相机对待侧物体进行测量 grab_image_start (AcqHandle, -1) while(true) grab_image_async (Image, AcqHandle, -1) get_image_size (Image, Width, Height) dev_set_part (0, 0, Height, Width) endwhile close_framegrabber (AcqHandle)

然后打开文件菜单栏选择到处语言导出C# xxx.CS文件，

导出C#代码：

在C#开发时，需摘抄部分代码移植到项目工程中，
