* Image Acquisition 01: Code generated by Image Acquisition 01
*关闭当前窗口，清屏
dev_clear_window ()
*打开图像采集接口，也就是打开相机开始采集数据
open_framegrabber ('GigEVision2', 0, 0, 0, 0, 0, 0, 'progressive', -1, 'default', -1, 'false', 'default', 'b0b35368a72b_GEV_MVCS00410GM', 0, -1, AcqHandle)
*抓第一幅图片，来确认窗口显示大小
grab_image (Image1, AcqHandle)
get_image_size (Image1, Width, Height)
*显示窗口
dev_open_window (0, 0, Width, Height, 'black', WindowHandle)
grab_image_start (AcqHandle, -1)
while (true)
    *grab_image_async (Image, AcqHandle, -1)
     *采集图像
     grab_image (Image, AcqHandle)
     *显示图像
    dev_display (Image)
    *转灰度图
    rgb1_to_gray (Image, GrayImage)
    *进行二值化处理
    threshold (GrayImage, Region, 0, 80)
    *填充区域
    fill_up (Region, RegionFillUp)
    *将不相连的区域整体分割成独立区域
    connection (RegionFillUp, ConnectedRegions)
    *根据面积大小选择目标区域
    select_shape (ConnectedRegions, SelectedRegions, 'area', 'and', 50, 2000)
    count_obj (SelectedRegions, Number)
    dev_set_color ('red')
*显示文字相关信息
    set_tposition (WindowHandle, 24, 12)
    set_font (WindowHandle, '微软雅黑'+'-Normal-34')
    write_string (WindowHandle, '有'+Number+'零件')

    dev_display (SelectedRegions)
