AI works in debug but doesn't log it.

So I am getting great shots of cars coming up the road. This is an Amazon truck with clear plates that it somehow missed.

Weirdly: I am playing back this video with AI debugging and in the right window it shows the plate, but on the left window I don't see it in the log on the left. It shows the Red window at least twice with 96 then 94% confidence.

My AI responds in about 134 ms, so I am trying 100ms captures and added more. Still no love.

Seperately, I am still missed some triggers. I went down to 15 FPS. Still issues. Maybe I will try 10 again.

Try setting your camera to 20 FPS and AI settings to + real-time images: to 20 and analyze one each: to 50ms

@wpiman If I view your video, the AI details on the left, for whatever reason, BI5 only sent 1 image to CP.AI, right?

And the image sent to CP.AI, did it have a license plate in the image? If no, then CP.AI won't have anything in image to pull plate #.

With respect to AI in debug mode, BI5 may be sending snapshots at different time points and if those snapshots have license plate in view, then CP.AI can process.

BTW, setting 110 images for each event seems excessive. You may be putting unexpected load on your CP.AI and thus your PC when enough events happens concurrently.

Ok, that makes some common sense....

I am probably going to pick up a 4060ti as well to accelerate the LPR...

 

[wpiman]

Ok. So I am still missing them some.



This one here, the image on the clips doesn’t show anything.

I am wondering if the trigger is too late in some cases.

Maybe I should zoom out.

You don't want to zoom out too far and then not be able to read plates.

It is a balance, and snow with salt-baked roads can be a problematic field of view based on color and dirtiness of car. While we can tell it is a car, the motion detection could miss it.

What are you motion settings page look like - probably need to increase motion sensitivity.

 

[MikeLud1]

Your zoom looks fine maybe point the camera up some so the plate is in the middle of the FOV

Post a screenshot of the Saved AI analysis details of the canceled alert, like the below screenshot.

Gravity might have pulled it down a tad. Good catch. I’ll muck with that tomorrow.

Here are my motion settings. Zone A is basically the road minus those bushes in front. Zone b is left and zone c is ten pixels to the right or so. Tells me direction.

Stupid question. Where is the cancelled alert? I’d love this info.

 

[wittaj]

Switch it from Edge Vector to Simple

 

[MikeLud1]

Stupid question. Where is the cancelled alert?

The canceled alerts are the alerts that say nothing found

 

[wpiman]

So the video I posed initially shows a cancelled alert. I NEVER get more than ONE of these even on a good capture that reports the plate..

ie. Mine looks nothing like yours...

 

[wpiman]

Here is a "good one". This one seems to catch it at the trigger....

 

[wpiman]

I wonder if in some cases my trigger is too late...

Since I have my pre-trigger set up, I wonder if it would be possible to have Ken either start the AI process with frames that happened BEFORE the trigger by some configurable amount.. Or maybe search through them if it didn't get a hit. The data is there.

 

[wittaj]

Weird. Mine goes backwards pre-trigger

 

[MikeLud1]

Post your Trigger settings

 

[wpiman]

Looks like mine that get a "hit" go backwards too.

I guess I am getting a hit BEFORE the trigger. Mine are showing every 50 MS then going backwards.... to 200 ms, then looks like many are not printing.... Not quite sure where the ones in the 100ms range are?

I assume that is because it wasn't better than the one that happened at T = 0 until T - 858ms?

Mike..

Attached and also see post #9 for sub menus...

5 seconds after the trigger.... Maybe that is too long? Wouldn't that just mean more processing?

Thanks again guys....
