求救车牌识别模糊问题

想识别这个车牌的内容，但是太模糊了，我是halcon12版本，有什么解决办法吗，求大佬解惑
以下是我的代码

1. *前期准备工作
   
2. dev_update_off ()
   
3. dev_close_window ()
   
4. read_image (Image, 'C:/Users/Public/Documents/MVTec/HALCON-12.0/examples/images/passat/passat_00.png')
   
5. get_image_size (Image, Width, Height)
   
6. dev_open_window (0, 0, Width*1.5, Height*1.5, 'black', WindowHandle1)
   
7. set_display_font (WindowHandle1, 24, 'mono', 'true', 'false')
   
8. dev_display (Image)
   
9. 
   
10. *初步处理图像
    
11. sobel_amp (Image, sobelImage, 'sum_abs', 3)
    
12. binary_threshold (sobelImage, Region, 'max_separability', 'light', UsedThreshold)
    
13. fill_up_shape (Region, RegionFillUp, 'area', 5, 5)
    
14. connection (RegionFillUp, ConnectedRegions)
    
15. 
    
16. *把车牌区域选择出来，得到的原始区域较多，可以使用多重条件筛选
    
17. select_shape (ConnectedRegions, SelectedRegion, ['rectangularity','width','height'], 'and', [0.6,70,20], [0.7,120,40])
    
18. count_obj (SelectedRegion, Number)
    
19. 
    
20. *在新窗口中显示获取的车牌区域
    
21. smallest_rectangle1 (SelectedRegion, Row1, Column1, Row2, Column2)
    
22. dev_open_window (0, 0,  Column2*1.3, Row2*1.3, 'black', WindowHandle2)
    
23. dev_set_window (WindowHandle2)
    
24. crop_rectangle1 (Image, LicensePlateImage, Row1, Column1, Row2, Column2)
    
25. dev_display (LicensePlateImage)
    
26. 
    
27. *对模糊图片进行处理
    
28. emphasize (LicensePlateImage, EnhancedImage, 5, 5, 2)
    
29. dev_display (EnhancedImage)  
    
30. 
    
31. *ocr识别
    
32. read_ocr_class_mlp ('Document_0-9A-Z_NoRej.omc', OCRHandle)
