OpenALPR monitors video streams in real-time to gather all license plates seen by your cameras. This data is browsable, searchable, and can trigger alerts. The Web server is available either:.

It shows a realistic example of the type of information you will soon be collecting from your cameras. First, configure your IP camera to capture the area that you wish to monitor.

The camera must be capable of capturing a clear image of the license plate in order for OpenALPR to properly identify the numbers. You may want to experiment with different angles, optical zoom levels, and resolutions to get the best image quality.

A straight-on shot of the license plate is best, but that is usually not possible, so OpenALPR can work with shots at an angle. Try to angle the camera so that the plate is clearly visible, and the vehicle is seen for as long as possible.

Some cameras support arguments in the URL to control resolution, frame-rate, etc. You may reduce the frames per second fps of the video feed in order to reduce the stream bandwidth. Fifteen frames per second is usually more than sufficient to capture passing vehicles from a fixed-camera.

The resolution also should not be too high. A resolution of p is generally sufficient for capturing license plates as long as the plate characters are legible.

Higher resolution often results in longer processing time without a gain in accuracy. The agent also stores all of the plate images in a rolling buffer on the hard drive.

There is a constant stream of data flowing between the camera and the agent as well as between the agent and the web server. The data sent to the cloud is relatively low-bandwidth because it contains text metadata describing the license plates. The OpenALPR Web Server does not store your plate images, these are downloaded directly from the agent when you select a plate to view from the web server.

The agent analyzes video streams from one or more IP cameras and finds the license plates for the vehicles that pass by the camera. We recommend a dedicated PC for the agent due to the amount of CPU used during processing; however, it can be installed on any machine. The next step is to configure the agent and add video streams to monitor. You may add any value into the alprd.

How are they indexed? The data is pure JSON, so no indexes or primary keys. The way that you organize the indexing I think would depend on your application and how you plan on using it. Can I have a python code that gives me the highest confidence of the same license plate detected while Pulling from the Queue with Beanstalkc.

Instead of outputting multiple results of the same license plate with different confidences as the same car passes by.

Here is Python 2x code for parsing the beanstalk results and printing only the top confidence plate and vehicle. Thanks for the code above, it also helped me as well. One question I have though, is it appears the results from the above code are delayed Several hours on average compared to the results from my OpenALPR Dashboard view.

Any idea why that would be? I am not sure if its a code problem, or a Beanstalk queuing problem. The results in beanstalk should be fairly instantaneous. How are you measuring the delay?

Maybe there is a difference in the system clocks between the camera and processing computer? Thanks for the response. I realized, I had both post to Webserver and WebSockets enabled in the alrpd. The best way to do it is to configure a second tube.

And your second tube alprd-alt can be drained and processed by you. CommandFailed: print "Tube doesn't exist" Watch the "alprd" tube; this is where the plate data is. If there is a job, process it and delete it from the queue. If not, return to sleep. JordanScott October 22,pm 6.

To help prevent fraudulent sales of stolen vehicles, there is already a VicRoads web-based service for checking the status of vehicle registrations.

The department has also invested in a stationary license plate scanner — a fixed tripod camera which scans passing traffic to automatically identify stolen vehicles. Understanding that these individual components existed, I wondered how difficult it would be to wire them together.

Streaming live video to a central processing warehouse seemed the least efficient approach to solving this problem. Using open source technology is a no-brainer. At a high level, my solution takes an image from a dashcam video, pumps it through an open source license plate recognition system installed locally on the device, queries the registration check service, and then returns the results for display.

For example, the image processing can all be handled by the openalpr library. I expected the open source license plate recognition to be pretty rubbish.

Additionally, the image recognition algorithms are probably not optimised for Australian license plates. I would expect part of that budget includes the replacement of several legacy databases and software applications to support the high frequency, low latency querying of license plates several times per second, per vehicle. Imagine a passive system scanning fellow motorists for an abductors car that automatically alerts authorities and family members to their current location and direction.

When you enter sensitive information such as a credit card number we encrypt the transmission of that information using secure socket layer technology SSL. We do not store your credit card information. This is the most stringent level of credit card security certification available. These images can be served within your network and do not need to be transferred over the internet to be displayed. The license plate data is stored on password-protected database systems that are kept isolated in a private network.

We also require you to enter a password to access your account information. Please do not disclose your account password to unauthorized people. Despite these measures, you should know that OpenALPR cannot fully eliminate security risks associated with license plate data and personal data and mistakes and security breaches may happen.

I originally thought this might be a problem with me running multiple models at once. One of the models was using Tensorflow and was taking the rest of the GPU memory. I neither loaded nor ran each of the other two models. Still same performance on cpu and hanging on gpu. Sign up for free to join this conversation on GitHub. Already have an account?
