How To Manage Car Exit Registration Of A Manufacturer Warehouse With Face Recognition And LPR?

RS

Hi all, we need your help with this case.

The problem.

Cars are being stolen from a manufacturer´s warehouse.

 

Scenario.

A car manufacturer has a warehouse where the new cars are stored and waiting for being driven outside of warehouse to their dealers by two differents types of exit.

Car exit type 1. There are two lanes with a guardhouse beside. The exit is controlled by vehicle barriers from guardhouse.

Car exit type 2. There are two exits with steel curtains and they are secured by a security guard.

 

What do they want?

The purpose of this project is managing the exit registration for the two types of exit. Access and exit control won´t be used but white list and black list will be used for showing alarms to an operator.

For car exit type 1 they intend to install four cameras just outside the guardhouse: two cameras for face recognition registration through front car window and two cameras for LPR registration.

For car exit type 2 they intend to install only one camera per exit at height of 1.8m just beside curtain. This camera will be used for face recognition registration through front car window. LPR wont´be used.

 

Please, help will be appreciated in order to design a solution for this project.

Do brand new cars have plates at all? Also, getting facial details thru the windshield is going to be very challenging.

Thanks for your comments Jon!!! 

Yes, all brand new cars have plates for local transit.

Do you have any suggestion for FR thru windshield?

Regards

I’ve never attempted to do this because of the challenges involved. You will have to get enough light inside the vehicles to ensure your subject is well illuminated. You also have issues with glare off the glass. Any tinted windows will obviously make this even more challenging. The best thing you can do is grab a car and a camera and see what happens. Play around with angles and lights until you get a satisfactory result.

Thanks again Jon, your comments and tips are useful for me.

I saw an impressive demo set-up last year at ISC West 2017 with a facial recognition camera and flash set-up that was designed to shoot thru a smoked-glass side window of a moving car.  Those interested, could get inside the demo vehicle, close the door and a picture was captured.  The results displayed were really surprising, their system seemed to work well (although the vehicle was not moving).  Unfortunately, I don't remember the Company's name, but maybe someone else may chime in for more info...

It really sounds awesome, thanks Gary. Hope somebody could share the solution´s name.

Why not conditioned the driver to roll down the window and facing the camera? If that condition is not met then the gate/barrier should not be opening, much simpler IMHO.

The face recognition for the exiting vehicles through the windshield is indeed challenging. 

I think face recognition should be captured at the time when someone is entering the vehicle and this means deploying a system with robust analytics capability and PTZ might play a pivotal role.

deploying a system with robust analytics capability and PTZ might play a pivotal role.

The more parts you have the more likely you will have reliability problems. You really need a way to get people to look at the camera unobstructed or otherwise you are going to have ongoing errors that will frustrate and upset the operators and the people driving in.

To be clear, even if you have a way where people look direct at the camera, I am not saying it will work perfectly but trying technical workarounds for obstructions will create too many issues.

I agree with you John, the scenario involves several factors that turn the project so complex.

Thanks for your comments and opinion.

Why don't you put a bar code access control/accounting system on the window of every car that is scanned when they drive past it. More reliable than LPR and not affected by window tint.  Sort of like access control but you can do it at longer distances.  You could  have a beam break sensor across the drive way so you'd get an alert if someone took the sticker off and drove through without it.

Thank you Scott, it is a really good option I will consider to propose.

If you search for it, there's really only one company that makes bar code systems.  I investigated it when weighing the pros and cons of that vs LPR.    LPR has the advantage of  not needing to issue any sort of credential, (since it's all done virtually) but it's still not 100% accurate.  I figure since you're going to have to physically touch every car for serial numbers and such anyway, putting a sticker on the side window shouldn't be that big of a deal.   The bar code stickers aren't that expensive in bulks of thousands and it will give you a hard, physical tracking to everything.

It seems like there are two objectives here, one to verify the driver has the authorization to drive out the gate. The second is to ensure the vehicle is authorized to leave.

 

How are license plates issued? When you say car manufacturer I am envisioning thousands of cars at a Ford plant, and they do not hold those cars very long.Or at least they aren't being moved often. License plates would not be permanent. Here in the US dealer tags would be put on. That is a generic tag of a special color that can be put on any vehicle in the dealer's inventory. Just because the car has a tag, doesn't mean it was assigned to that car. Tags can be moved easily.

 

From what I gather, the guard is still going to open the gate, but there needs to be some form of ID of the driver?

 

Why not a card reader? Maybe with a photo and that photo would pop up in the guard booth so the guard can see the driver, and verify they look like the owner of the card? Or even dual verification with a card and PIN? You can lose a card, and you can share a PIN. You can obviously share the card and PIN, but it seems like the accountability would be 100%. Bob how did this guy drive off the lot using your card and PIN? Or remotes?

 

As far as the vehicle, do they get barcodes for inventory? Surely they don't manually input VIN #'s manually when moving inventory? I would try to use the VIN# to ID the vehicle. If no barcode, how about OCR of the VIN through the dash, or even requiring the door to be opened and getting the VIN from the door decal?

 

 

 

I think trying to facial recognition is going to be a challenge and IME guard booth operators do not have a lot of technical skills. There will probably be a lot of false reads, which will require a manual process, which may create bottlenecks, etc.

Thank you for you comments, Ray. May be it could be a good idea to strength some operation process as you comment and combine some technology methods to give a best security results.

Not sure what you are trying to say but you ever hear of KISS? Keep it simple stupid.

 

I think this is more complicated than it needs to be. You just need to authorize users and vehicles out of the parking area.

Rodrigo- Found the name of the company I discussed prior that I saw at ISC last year.  It was Gatekeeper Security, they displayed how to capture an image though smoked glass - their system solution was was called "Intelligent Vehicle Occupant Detection".  

Here is how they describe the product from their website- GatekeeperSecurity.com

With Gatekeeper’s patent pending Intelligent Vehicle Occupant Detection (IVOD), security officers can see inside vehicles as they approach entry gates and know who is inside with accuracy and speed. The high-resolution machine vision camera is optimized for both day and night operation,  the camera is paired with a powerful targeted array of LED lights that illuminate the driver and other occupants even through tinted glass, sun glare and at night. Using advanced image processing, the driver and passengers are highlighted while windshield glare from sunlight or overhead area lighting is removed through Gatekeeper’s advanced computer vision algorithms.

Good luck with you hunt for a the correct solution.

Interesting.  Gatekeeper's website offers some details that help understand their claims:

The hardware key is essentially an camera equipped IR floodlamp

Using IR, the system floods the inside of the vehicle with IR light, which the camera picks up.

An analytics package counts the number of, or 'recognizes' where possible the visible faces:

Being that the system uses IR, traditional UV window tint doesn't block the IR camera.

Given the other variables like shutter speed and camera position are appropriate (as previously noted, difficult to do), there's no black magic high tech here. 

You're just deluging the inside of vehicle cabs with light.  If subjects are ducking behind seats or the camera cannot see clearly into the vehicle, this system is not going to work.
