    image corruption

    Quick update. I've found that the default settings on the camera are terrible for LPR. The color saturation was too low for me to tell the color of the tags, and overall the image was too soft and probably contributed to the OCR error rate slightly. I've bumped color saturation, contract...

    It sort of depends on your camera. Dedicated LPR no-config-possible cameras: Aim and mask is all you can do. Not ideal, but for one of my cameras, I've mounted it very high and aimed it at the middle of the street, and I've only had 1 problem--a 24ft box trucked was tall enough to block it...

    How to capture multiple plate reads in quick succession?

    Do you have another computer on the network that is as fast as your NUC? If so, you can try running CPAI on that instead of your BI machine. This will reduce the CPU load and avoid BI and CPAI competing for the same resource.

    image corruption

    Could be. The sprays are usually not effective in daylight, but that could be a very dirty plate, too. I'll post the next one that I see that I know doesn't have a plate cover, paper, or dirt. It happens a few times a day.

    image corruption

    I was at 2048, bumped it a few times to 4096 on a 1080p stream. It'll take me a day or so to see if it makes a difference. I'm trying to improve stuff like this... (I believe this was when I had hw decode turned off) This is my typical

    Update: Intel Beta worked for about 6 hours before Miller Time. Back to CPU.

    image corruption

    Thanks @wittaj, I always learn a lot from your details replies. :) I just tried the Intel hw decode (was using intel +vpp) and I was still getting the corruption, so I switched to Intel Beta just to see what happens. Yeah, I was having some BI issues, and one of the first things support...

    image corruption

    Disabling hardware accel worked. Doesn't seem to make the CPU work any harder either. The quality does seem poorer tho, i'm going to flip it back on and see if the quality improves.

    Hey @MikeLud1 I see this once in a while (maybe 1 in 1000 plates) where spaces in the middle causes the OCR to reverse the order, it only happens when there is a space in the middle. Any idea what's causing it? I'm running the current version on an RKNN. It doesn't happen every time either...

    Can't wait to see the beta.

    I noticed that the image (stills) quality seems to be less sharp with decode accel disabled, is that my imagination? Thanks

    image corruption

    This is from a Uniview camera on H.264 10fps, 1/5 key frame. I don't see this when looking at the web interface on the camera, but when I look at BI, this is pretty common at night, and happens from time to time during the day. Any idea what might be causing this? I am using decode...

    How to capture multiple plate reads in quick succession?

    A quick way to see if more CPU would help would be to unpark the cores you have.

    What does your resource monitor show BI and CPAI as using?

    How to capture multiple plate reads in quick succession?

    Yeah, one of the super annoying things about BI is that the DAT file doesn't tell you why it's canceled. If someone knows how to determine that, I'd love to know.

    How to capture multiple plate reads in quick succession?

    Look at the other plate misses, if it's all the same pattern, where it would miss the plate if it wasn't found in the pre-trigger images (where the T values are negative) and a few in post, then you can try lowering the pre-trigger images to a smaller number (like 2) and see if that helps.

    How to capture multiple plate reads in quick succession?

    Yeah, the logs on CPAI are not useful (unless you are seeing red, which means the module probably has to be restarted). .DAT file is where all of the answers are. My guess is that it was canceled well before all of your images were sent.

    7W to do it on the Orange Pi vs 180W on your Xeon. :) I'm in California, where power is more expensive than Fentanyl.

    How to capture multiple plate reads in quick succession?

    Those look like the default, you can try bumping timeout to 30s or 45s if you believe it's taking a while for CPAI to return the results. If it's taking too long, then consider the Rockchip board, but I think you should take a closer look at your triggers and the DAT file first. Pay close...

    after dropdb, you might have to createdb -U postgres postgres before the schema, but either way, reinstall (fresh pull) would have accomplished the same.

    Have you tried deleting your database container and then doing a docker compose pull? and if it doesn't come up, do the database schema, migration, and see if that helps with a clean start? Or maybe just do this: dropdb -U postgres postgres psql -d postgres -U postgres -f...

    How to capture multiple plate reads in quick succession?

    I am not sure that's the conclusion. My understanding is that as long as your BI is actually sending images with multiple plate, and as long as CPAI is able to process it before the timeouts on BI, this should work. Images are queued on BI until timeout, and if you hit timeout, it stops...

    Yeah, strange. Did you check the md5 of schema and migrations? Probably not the issue since it's complaining that the columns exist.

    Can you issue the same db command but -f migrations.sql instead? Also, cut and paste this into BI on alert settings, just in case it's something simple {"ai_dump":&JSON, "Image":"&ALERT_JPEG", "camera":"&CAM", "ALERT_PATH":"&ALERT_PATH", "ALERT_CLIP":"&ALERT_CLIP", "timestamp":"&ALERT_TIME"}
