Adding support for NZ number plates #373

Open jLynx opened 8 years ago

jLynx commented 8 years ago

Hi What would I need to do to add support for New Zealand number plates?

They should be quite easy to add as they are only black and white with a max of 6 characters and they are only alphanumeric.

Here are two examples.

nz_meowdi test car plate

Here is the font https://sparkytype.com/licenz.php

Duplicate Issue: #342 Also on that note, I just downloaded this for a project of mine, default configuration picked up my car and another car, i think it was under the USA config

For start u need to collecet real image from NZ plates... then u need to train detector and make OCR traendata.... ( OCR tran ) If u collect image let me know I will help you

jLynx commented 8 years ago

@vladimirr0708982 You just need an image of every character and then a bunch of licence plates on cars in different situations correct? If so I would love your help and I can get that by this time tomorrow

vladimirr0708982 commented 8 years ago

Simple image like you post, real image from field... they I will explain u on mail/skype what u need to do... more image u have accurensy will be better

jLynx commented 8 years ago

Ok I will get them sorted then I will contact you tomorrow on when I have them.

Thanks mate

chriswiggins commented 8 years ago

All, I'm keen to get this sorted and working and can help out in quite a significant way (lots of images pre-processed)

@darkn3ss61 want to take this offline and work on it collaboratively?

jLynx commented 8 years ago

I have been really busy lately hence why I haven't done any more work on it. But yeah I could be interested @chriswiggins

3ph commented 8 years ago

Hi guys, I'm interested as well. Can you please let me know what's the progress or if you need any help? Cheers

chriswiggins commented 8 years ago

@3ph: I've currently got the plate read accuracy to approx 85%, will be making this better over the next few weeks. Currently waiting for the region detection training to finish (this takes ages!! )

Will keep everyone posted where I get to

chriswiggins commented 8 years ago

@3ph @DarkN3ss61 actually, you could both help me with classifying the characters to make the reads more accurate - email me at chris [at] wiggins . nz and we can go from there?

wub commented 7 years ago

@chriswiggins @3ph @jLynx Hey guys, was there any progress on this that you know of?

chriswiggins commented 7 years ago

Hi @wub, there was progress, and there is a company in the UK looking at helping with this at the moment. We've got a basic tessarect file (for the OCR) but its not quite good enough yet. Are you willing to help classify OCR engine? Its quite a lot of work

jLynx commented 7 years ago

I have just noticed that OpenALPR now supports NZ plates here: http://www.openalpr.com/cloud-api.html

I wonder if we can get access to that

TehRobot commented 6 years ago

Is there a working config for this that can be used for a local install yet? Or only cloud based?

danielfaulknor commented 6 years ago

+1 I just spent all day building something around the locally hosted option, only to discover NZ is only supported on cloud :(

trikonz commented 5 years ago

we have this working very well on locally hosted

danielfaulknor commented 5 years ago

@trikonz care to elaborate on how?

Jake-01 commented 5 years ago

@trikonz I'm also after the nz.traineddata would be great to know where to find it

Jake-01 commented 5 years ago

@chriswiggins how'd you guys get on? I'm aware it's been a while since you where working on it but if it's still being worked on do you need a hand?

icepicknz commented 5 years ago

I'd be very interested in there NZ train data too, did anyone complete this? @vladimirr0708982 if I get a whole lot of images are you willing to assist?

danielfaulknor commented 5 years ago

No luck here. @trikonz's drive by comment was the closest we've come...

icepicknz commented 5 years ago

the docker version posting to the cloud picks up NZ plates every time. I took a look at their files in the docker and I see the runtime_data/config/nz.conf file.

Problem I have is the docker version doesn't appear to be using the tessdata files so I can't just copy them, they do still have files in the OCR folder just cf_m.enc cf_w.enc ov_m.enc ov_w.enc province.labels th_m.enc in the aunz folder, I need something like lau.traineddata for NZ.

Wonder how they doing it in the docker, or if the plate is looked at in the local agent then uploaded for classification and reading in their cloud?

Jake-01 commented 5 years ago

@icepicknz I'd be keen to work with you and try and see if we get working build going. I've started collecting pics of plates myself

icepicknz commented 5 years ago

interested, will try get some photos over the next week or so; have you figured out the training part?

TehRobot commented 5 years ago

Very much for getting this sorted also. There has been talk of people having this but I am yet to see anyone sharing their training data. I am happy to put my CPU power to doing the hard work but just need a little guidance as to how to do it.

As for getting plate images, TradeMe. literally THOUSANDS of images with different nz plates on there. Just a matter of taking the time to troll and download.

MattL-NZ commented 4 years ago

Hey all, just wondering if anyone has made some progress on this? Looking for NZ Data for my application.

lip-andrade commented 3 years ago

Hi, sorry to resuscitate the topic, but did anyone ever find a solution for NZ plates in a self-hosted config?
