Shape template matching based on Halcon learning [vi] find_ mirror_ dies. Hdev routine

* Many molds are usually etched on the wafer . Before the single track, the mold can be picked up by the mold bonding machine and placed on the lead frame , They have to be cut from the wafer . The mirror mold is used to determine the parameters of the cutting process .

* ad locum , The position of the mirror mold is based on shape matching .

1、 Read the picture

dev_update_off ()
* close window 
dev_close_window ()
* Read the picture 
read_image (Image, 'wafer/wafer_mirror_dies_01')

* Open the adaptive picture window 
dev_open_window_fit_image (Image, 0, 0, -1, -1, WindowHandle)
* Set display font 
set_display_font (WindowHandle, 16, 'mono', 'true', 'false')
* Set the width of the line 
dev_set_line_width (3)

* display picture 
dev_display (Image)
disp_message (WindowHandle, 'Determine the position of mirror dies on the wafer', 'window', 12, 12, 'black', 'true')
disp_continue_message (WindowHandle, 'black', 'true')
stop ()

 2、 Create a template

* Cutout 
gen_rectangle1 (Rectangle, 362, 212, 414, 262)
reduce_domain (Image, Rectangle, ImageReduced)

* Create a template 
create_shape_model (ImageReduced, 'auto', rad(0), rad(1), 'auto', 'auto', 'use_polarity', 'auto', 'auto', ModelID)
* Get the outline 
get_shape_model_contours (ModelContours, ModelID, 1)

 3、 Start matching

* Read the picture and deal with it 

* To begin for loop 
for Index := 1 to 4 by 1
    read_image (Image, 'wafer/wafer_mirror_dies_' + Index$'02')

    * Determine the position of the rearview mirror mold , And calculate the running time required to find the location 
    count_seconds (S1)
    * Begin to match 
    find_shape_model (Image, ModelID, rad(0), rad(1), 0.5, 0, 0.0, 'least_squares', 2, 0.5, Row, Column, Angle, Score)
    count_seconds (S2)
    Runtime := (S2 - S1) * 1000
    
    * Show results 
    gen_cross_contour_xld (Cross, Row, Column, 6, rad(45))
    dev_display (Image)
    dev_display_shape_matching_results (ModelID, 'lime green', Row, Column, Angle, 1, 1, 0)
    dev_set_color ('orange')
    dev_display (Cross)
    disp_message (WindowHandle, |Score| + ' mirror dies located in ' + Runtime$'.1f' + ' ms', 'window', 12, 12, 'black', 'true')
    if (Index != 4)
        disp_continue_message (WindowHandle, 'black', 'true')
        stop ()
    endif
endfor

notes ： Here is a special operator , Make the results more visible

* Generate a cross shape for each input point XLD outline .
gen_cross_contour_xld (Cross, Row, Column, 6, rad(45))
