Stop Object Detection (YOLOv5 6.2) and start Object Detection (YOLOv5 .NET) it is faster

ok... done...

Something does not look right maybe go back to Object Detection (YOLOv5 6.2) and we can see what is wrong with Object Detection (YOLOv5 .NET) tomorrow.

is there a more GUI way of seeing the plates caught other than shifting manually through the logs?

Use this utility I referenced in your other post.

LPR Software

What is everyone doing for their LPR capture software? Right now, I'm using Blue Iris with platerecognizer.com as the Plate Recognizer for ALPR, but it has some limits. Namely, it only seems to capture 1 snapshot from an approaching vehicle, so you have to activate it at just the right time...

I have looked at that over the past couple of days and got totally lost. the post you referenced seems to be mid way through several other pages of threads, etc... do you know of anywhere that there are steps to follow, ie, step 1) download/install this... step 2) change this config, step 3) etc... ?

Um I clicked that link and it opens on post #1 of that thread on NodeRed complete with the steps?

Node Red Dashboard for Blue Iris ALPR

@Alan_F I am confused here; Create a separate folder to store the images where ALPR detected a tag (outside Blue Iris) The original images are deleted when Blue Iris deletes the clip/alert. Copying them elsewhere allows you to keep them as long as you want This folder should be local to the...

@MikeLud1 - Any chance you are around today to help me figure out how to get the plates to come kind of graphic interface? ie, PlateRecognizer or something better?

Currently I do not have any kind of graphic interface for you to use. The best that is out there is the Node Red Dashboard that @wittaj posted.

I'm SOOOOO annoyed right now... we just had the vehicle that the neighborhood suspects of all the thefts in the neighborhood drive by my cameras - and for whatever reason, they didn't trigger to catch the video and plates. Like they didn't trigger at all from the rear of the vehicle side. They did trigger from the headlight side, but of course no plate on that side. I have my zones set up to basically cover the entire road in each direction. I have my motion set to trigger with a min. obj size of 100 and min contrast of 12 (the lowest possible settings) and I have my object travels set to 25, also tried 10... which is crazy low... and yet, on the back side of the vehicle at night time it's NOT triggering capture. It was triggering correctly prior to making the changes I made to get LPR to work... am I missing a setting somewhere or is the LPR settings/solution somehow making the trigger less sensitive? Any thoughts @MikeLud1 or anyone else? Thanks!

You cannot use Edge Vector at night, especially for plates.

I mentioned previously, uncheck the object moves X number of pixels and uncheck the reset at X% - those are only used to eliminate false triggers and you have the opposite going on. NONE of my cameras use those settings.

If you are not recording continuously, you should also do that in the event motion doesn't trigger an alert.

Which one should I use instead of edge vector and will whatever that is work ok for daytime?

 

[wittaj]

Since you are using Code Project to weed out the false triggers, I would use simple algorithm for both day and night and let Code Project decide if it meets the AI criteria.

This. Any important cams you should run continuous in some form. Substreams at least. Too many times things can be missed otherwise and storage is cheap.

I put the two license cams on continuous. I have them on a 10TB drive... How many days do you think I'll get out of that?

Depends on the resolution and bitrate and what else is going to it:

Calculating Required Hard Drive Size

We have built a calculator for you to use and save your results. Click here to use it. To calculate required storage space for cameras, you only need to know two things: The average bit rate, and the amount of time. Then multiply them together with Google, being careful to use the correct...

And then using substream will get you more storage based on how much it triggers to mainstream.

 

[wittaj]

Recording a D1 substream with a decent bitrate won't take up much space but will also capture those that don't trigger:

How much resolution is really needed for LPR

We have folks come here all the time thinking that more MP is better, whether it be for general purposes or for LPR. Those of us that have been around long enough know that sensor size is more important than MP. Those that have been here awhile know that I share a representative sample of...

Does anyone have any idea where these images are stored? I'm trying to fine tune my trigger points and being able to see what snapshots it is looking at to analyze the image for a plate would help. My license plate reader is functioning, but is very random on whether or not it finds a plate to analyze. The plates are VERY clear in the video's.

Right click on the alert and click on Open Containing Folder. Also you can hold down the CTRL key and double left click on the alert and the last screenshot will popup.

I don't have anything like that in my clips on the left, definitely not any zoomed in plate images... I just have the 5-20 second video clips over there. nothing when I click the alerts lightning bolt.
