120-180 degree camera with stitched image.

[rahhazar]

I am trying to test lpr on cameras with multiple lenses with stitched image which covers between 120 degree to 180 degree.
Thanks in advance.

I did select this camera (IPC-HDBW4231F-E2-M)
not sure if it will give me LPR with a distance of 20 meters between the camera and the intrusion line. what size of lens do you guys recommend (it will be mounted 10m high and will watch 39m left and 39m right total of 78 meters.

I think you are going to need more focal length at 20m. At least 12mm I’d guess and I don’t think that would be enough.

Hi @rahhazar

I do like the IPC-HDBW4231F-E2-M, however not for longer distance image capture.

You will need a tighter FOV as noted by @biggen to capture license plates at 20 meters... see the DORI section of the cliff notes iirc 80ppf is needed for a good license plate capture if the plate is basically straight on to the camera.

the correct distance is 10m high and will watch 39m left and 39m right total of 78 meters. I made a mistake there.

lets see if i can find another booby camera that can do this job.

So you need 40m each direction? You're only option is two bullets each looking the direction you want. Install two of these:

I want the whole 78 meters under fov too for this to work.

Not gonna work like that. You can use three cameras: One for the overview using the boobie and then two for dedicated LPR usage. That is the typical setup anyway. Always need an overview cam in addition to a LPR camera.

Hi @rahhazar

You are going to need to open up your piggy bank to meet those requirements as that requires a significantly better set of cameras / or one massive single unit composed of multiple cameras.

Normally using multiple cameras works better for your budget to meet the requirements you have spec'ed out.

hmmm let's see if I can find a guy through Upwork to make them work together for me and how all plates in my overview feed.

i have a budget of 50k for this project any thing under that amount does the job.

Unless the Upwork guy can bend the rules of physics to his will, there is no way a 3.6mm camera is going to get readable plates at 40m. No way no how...

I meant take lpr from bullet camera and show it in overview camera feed. Using 3 cameras together.

 

[rahhazar]

welp welp, the guy o UPWORK struck me with $80k ask to create an application and have the license plates from lpr camera appear in overview camera feed on each vehicle.

 

[biggen]

$80k USD?!? For an overlay?!?

 

[wittaj]

I am in the wrong business LOL

yes USD, I sheet my pants reading it.
