I'm pinching. Do you have an idea for an idea? Did you manage to solve?
I'd also like to know if you found any solution!
After some time, I came to the conclusion that the reason for incorrect reading is a small verification sticker on the license plate. When we retouch it, the algorithm works good.
alpr -d -c eu --config /home/pi/openalpr.conf --clock /home/pi/mik.jpg Total Time to process image: 312.825ms. plate0: 10 results -- Processing Time = 124.663ms.
Now how to improve it in the code or config?
segmentation_min_speckle_height_percent = 0.2 segmentation_min_box_width_px = 5 segmentation_min_charheight_percent = 0.4 segmentation_max_segment_width_percent_vs_average = 2.0
Hello. I have a problem with Polish number plates with the letter I in the 3rd position. I use in openalpr.conf settings ocr_language = leu. Examples: 1. alpr -c eu --config /home/pi/openalpr.conf --clock /home/pi/IMG_20180801_180432.jpg Total Time to process image: 441.7ms. plate0: 8 results -- Processing Time = 239.964ms.
alpr -c eu --config /home/pi/openalpr.conf --clock /home/pi/IMG_20180801_181042.jpg Total Time to process image: 396.535ms. plate0: 10 results -- Processing Time = 203.787ms.
alpr -c eu --config /home/pi/openalpr.conf --clock /home/pi/IMG_20180801_182437.jpg Total Time to process image: 260.946ms. plate0: 6 results -- Processing Time = 136.325ms.
But with license plates with the letter I in the 2nd position is Ok:
alpr -c eu --config /home/pi/openalpr.conf --clock /home/pi/IMG_20180801_182142.jpg Total Time to process image: 430.729ms. plate0: 10 results -- Processing Time = 296.253ms.
