How do I improve the Vehicle Detection Rate and License Plate Recognition Accuracy?

Hello, dear!

Have a good day to you!

Please refer to the following tips to improve it!

1. Adjusting camera installation.

   Adjust the camera installation location, shooting angle, and height. For details about the installation requirements, see IPC Installation Requirements.
   

2. Configuring image quality.

   Set image parameters to adjust the duration the license plate stayed in the image and definition of the license plate. For details, see Image Quality Commissioning.
   

3. Commissioning the VCM.

   Adjust the ROI area and license plate recognition algorithm parameters for VCM to perform license plate recognition. For details about how to commission the VCM, see Configuration in the VCM.

I hope the answer can help you!

•    Background Update:
  
  

•    Reading the background image.
  
  
•    Reading the current frame.
     
•    Converting image frame from RGB to HSV color model
  
  
•    Converting image from HSV to Grayscale model.
     
•    Converting Grayscale to Binary image.
     
•    performing Median Filter to remove noise.
     
•    Boundary label the filtered image.
     
•    Tracing region boundaries in a binary image.
     
•    Displaying the result
  
  
  

•    Color Segmentation
  
  

•    Reading background Subtraction resulting image.
  
  
•    Selecting specific color for segmentation.
  
    
  
•   Normalizing color values by Multiplying with 255. Where values are between 0 to 1.
  
    
  
•    Comparing frame image pixels with the color rang.
    
  
•    Isolating the selected color from the frame image.
