- 关于显示类函数解释
dev_update_window (‘off’)
read_image (Image, ‘plastic_mesh/plastic_mesh_01’)
dev_close_window ()
get_image_size (Image, Width, Height)
dev_open_window_fit_image (Image, 0, 0, Width, Height, WindowHandle)
set_display_font (WindowHandle, 18, ‘mono’, ‘true’, ‘false’)
dev_set_draw (‘margin’)
dev_set_line_width (3)

endfor
处理思路
这个例子是主要讲解了动态阈值在缺陷检测中的应用。
