Hi

 

Has anyone played with or had any experience with the Geovision License plate recognition.

 

I have just received and will be setting it up in the next couple of days.

 

if any one has any tips or tricks to look out for that would be great.

 

thanks

I would recommend using I/O to trigger the recognition, such as a laser beam etc.

 

What camera(s) are you using, also 1 lane or 2 lane, or more?

[aarons 0]

1 lane at this stage

 

is the motion detected way unreliable?

 

I was hoping to use this way

 

Can you easily run on same machine as GV main system ? or is that a nightmare

 

Any other info or brief case study would be great

With MD the recognition success would probably not be higher than 80-85%. With I/O you can achieve 99%.

 

You can use motion but you'll never get the best recognition.

 

Saying that, I've seen the GeoVision LPR System running on MD and it was performing well. A speed bump was installed however, to help slow the vehicles down.

 

When setting up, take some time playing around with the masking to make sure when the LPR System is triggered by the vehicle, it is in the best possible position and at the right angle.

 

If the angle of the camera is more than 30 degrees then your recognition will be affected.

 

You can use 1 machine for GeoVision and the LPR System but this is usually dependent on the GV Card you are using, the amount of cameras, the number of LPR Lanes and the recognition type (e.g. motion or I/O).

 

If you wanted to use a GV800-4 with a 1 lane LPR on IO that would probably be ok but on motion, the pc would be working a lot harder so you might experience a delay in your license plate capture.

 

Most people stick to separate systems, especially if they have quite a few cameras on the main system and are using MD on the LPR.

use a seperate PC. and also use specific LPR cameras.

Motion works fine with decent LPR cameras, eg. Extreme. We get it 100% of the time ourselves, though in this particular case we arent using the Geovision LPR software, just the DVR. Also we have a speed bump .. if you dont want to rely on the motion record then use a simple Optex Photobeam.
