Check the below settings in the ALPR camera because the file path.txt is not updating
Blue Iris and DeepStack ALPR
- Thread starter MikeLud1
- Start date
same settings.
just went down the driveway and got these files. and a DAT file in same folder as image and a JSON file in ALPR folder.
It looks like it is working now, just not reading the plate correct.
I am very happy for your help with this.

Make sure you set the below to Hi-res JPEG files on both cameras. I need to add this to the instructions. Also the ALPR camera should be a zoomed in image of the plate this should help the OCR image_x and image_y setting will do this.
One last thing attach the jpeg file that is in the www/ALPR folder, this will show if you have the X and Y settings correct.
I think it is correct now. with the exception of recognizing the digits on the plates.

My ALPR camera was on "database only" now it is changed. Now I wait for a plate to capture.
I think you can see it by yourself in #62

I think it might be related to the below issue. I am going to try to fix it tonight. Also your country has "|" at the beginning of the plate that is impacting the accuracy.
@MikeLud1 Really nice work on the integration. I had a similar idea to use deepstack license plate and some OCR model , but to avoid BI since it is not very convenient to lookup license plates history, and sometimes not very reliable.
Any idea how hard would it be to use this integration to push data to other system perhaps something custom made? And use something else to feed images to it.

I am thinking of something in the future. For now you can open the log file in Excel.
I think I fixed the below issue. I am going to test the fix overnight. If it works I will issue Version 2.2. If you are on version 2.1 no need to redo everything just replace "DeepStackALPR.exe" file.
I started looking at image enhancement (auto contrast) to help the OCR. The plate on the right is without auto contrast and the left is with, I might include is V2.2
Have some updated images and log files. Some af the cropped snapshots doesn't show the whole plate.
The logfile.txt and other files are located in the folder from 2022-01-10. No new folder from ALPR camera today.
Just an update.

Try the below setting this will increase the cropped plate size and help get the whole plate.Have some updated images and log files. Some af the cropped snapshots doesn't show the whole plate.

; Blue Iris short name for cropped licence plate camera and resolution settings
camera = ALPR

The issue is with your trigger setting, post screenshot of them, does it show up in the canceled alert.

I am loving this thread. Thanks Mike. I spent about an hour or so yesterday and it never worked, but I believe the issue is on my configuration. The snapshots that are going into the alert folders are "off time" (a car triggers it, but the jpg that gets saved is eitehr before or after the license plate is out of range). I don't have time to look into it for a while (and this is definately not a mission critical issue for me). I would post my settings, but I uninstalled the ALPR completely for now. The python script in it was causing slightly higher CPU usage than I am comfortable with until I have time to look at it some more. Thanks for everything you're doing Mike!!!!!!!!
