The gate control will be able to work automatically without or with a very little efforts and also the system will be able to recognize license plates from cars at the entrance gate and take an action to let the cars enter or not. It grabs video frames which include a visible car license plate and processes them. The proposed system has been implemented using Python, Convolutional Neural Networks, etc. We need a high-resolution camera with infrared capabilities, so photos can be captured from the vehicles regardless of the time of day.
We will collect front images of the vehicle. We need to fix the lights such that it should not reflect on the driver. The angle of the camera should adjust so that it should fall on the front part of the vehicle.
We need to trigger our camera to capture a photo of each passing vehicle. There are many methods to accomplish this, the main ones being radar and motion detection. Once the camera captures the images of a car using the methods mentioned above, we grab upto 5 frames per second and enhance the frames using a few python in-built libraries.
Then we applied pre-trained models on the frame. With this technique, we were able to detect the number plate from the frame. We should check the skewness of objects because sometimes there is a chance to get different orientations to improve the quality of the number plate label for better accuracy in results.
Finally, we save the recorded video along with the number plate information captured in a database.

Many law enforcement agencies store ALPR data for years, and share it with other law enforcement agencies and federal agencies. The length of time that ALPR data is retained varies from agency to agency, from as short as mere days to as long as several years, although some entities—including private companies—may retain the data indefinitely. The companies then share the commercially-collected data not just with law enforcement but also with auto recovery aka "repo" companies, banks, credit reporting agencies, and insurance companies.
Data collected by private entities does not have retention limits and is not subject to sunshine laws, or any of the other safeguards that are sometimes found in the government sector. ALPR is a powerful surveillance technology that can be used to invade the privacy of individuals as well as to violate the rights of entire communities. Law enforcement agencies have abused this technology.
Police officers in New York drove down a street and electronically recorded the license plate numbers of everyone parked near a mosque. Police in Birmingham targeted a Muslim community while misleading the public about the project. Moreover, many individual officers have abused law enforcement databases, including license plate information and records held by motor vehicle departments.
In , a Washington, D. In addition to deliberate misuse, ALPRs sometimes misread plates, leading to dire consequences. In , San Francisco police pulled over Denise Green, an African-American city worker, handcuffed her at gunpoint, forced her to her knees, and searched both her and her vehicle—all because her car was misidentified as stolen due to a license plate reader error.
Her experience led the U. Aggregate data stored for lengthy periods of time or indefinitely becomes more invasive and revealing, and it is susceptible to both misuse and data breach.
Sensible retention limits, specific policies about who inside an agency is allowed to access data, and audit and control processes could help minimize these issues. One of the better privacy protections would be for police to retain no information at all when a passing vehicle does not match a hot list. EFF has been investigating and combating the privacy threats of ALPR technology through public records requests, litigation, and legislative advocacy since The agencies claimed the records were exempt from the California Public Records Act because they were investigative records.
In , the California legislature passed S. The law also prohibits public agencies from selling, sharing, or transferring ALPR data except to other public agencies. EFF has coordinated volunteers to collect ALPR policies across the state of California and to expose agencies failing to comply with the law. EFF has also independently filed public records requests with dozens of agencies to shine light on their use of ALPR data.
EFF investigated more than ALPR cameras operated by law enforcement that were leaking data because of misconfiguration. These cameras were inadvertently publicly accessible through web browsers and Telnet interfaces.
We have also contacted public safety agencies whose ALPR data was exposed online, often on websites accessible to anyone with a web browser, to responsibly disclose the security vulnerabilities we found. Neal v. Fairfax County Police Department. San Francisco—On Friday, Jan. Washington, D. The Electronic Frontier Alliance is made up of more than seventy groups of concerned community members, often including workers in the tech industry who see issues of the industry from the inside.
Plate orientation and sizing - compensates for the skew of the plate and adjusts the dimensions to the required size 3. Normalisation - adjusts the brightness and contrast of the image 4. Character segmentation - finds the individual characters on the plates 5. Optical character recognition 6. ANPR is an automatic surveillance method that uses optical character recognition on images to read vehicle registration numbers. Infrared cameras record the registration numbers of vehicles entering and exiting the car park.
There are a number of benefits of using the ANPR systems. The cameras are unobtrusive, inexpensive to run and more efficient than monitoring a car park manually.
