Introduction

In this video, we will explore an algorithm that extracts and stores car number plates in real-time. By using computer vision techniques, this algorithm locates the car front, detects the number plate area, and extracts the text from the number plate. The extracted data, along with the entry and exit times, are then stored in a database. In this article, we will delve deeper into each step of the algorithm, discuss the challenges faced during implementation, highlight the benefits, and provide contact information for those interested in acquiring the algorithm.

Overview of the Algorithm

The algorithm consists of three main parts: locating the car front, object detection for the number plate, and extracting the text from the number plate. Each frame of the input video is processed, and the extracted information is stored in a database. Let's dive into each part of the algorithm and understand how they contribute to the overall functionality.

1. Locating the Car Front

The algorithm begins by identifying the car front from each frame of the input video. The car front area is cropped and stored in the database for further processing. This step ensures that only the Relevant region containing the number plate is considered for further analysis.

2. Object Detection for Number Plate

Once the car front is isolated, the algorithm utilizes an object detection model to locate the number plate area within the cropped image. This step plays a crucial role in accurately identifying the region where the number plate is Present. The detected number plate area is then stored as a separate image for text extraction.

3. Extracting Text from Number Plate

In this step, a custom object detection model is employed to extract the text from the cropped number plate image. This model is specifically designed to recognize and extract text data from images. The algorithm retrieves the characters present on the number plate and stores them for further processing.

4. Storing Data in Database

After extracting the text from the number plate, the algorithm proceeds to store the data in a database. The associated image of the car, timestamp, and the extracted number plate are stored. This ensures that the relevant information is preserved and can be accessed later for various purposes.

5. Time Extraction and Record Storage

One of the primary objectives of this algorithm is to keep track of the entry and exit times of each car in a parking lot. The algorithm records the timestamp when a car enters and exits the parking area. By calculating the time spent by each car, valuable insights can be derived for managing parking spaces efficiently.

6. Challenges Faced in Implementing the Algorithm

Implementing this algorithm poses certain challenges. Many attempts by different individuals have resulted in failure due to the usage of inadequate test racks. The algorithm requires specialized techniques for extracting car number plates, which are different from those used for general text extraction. These challenges emphasize the importance of understanding the specific requirements of the algorithm and implementing it accordingly.

7. Benefits and Commercial Use

The algorithm provides several benefits, such as real-time car number plate extraction, accurate time Recording, and database storage. It is designed primarily for commercial purposes, offering valuable insights for managing parking areas, monitoring traffic, and enhancing security systems. The algorithm can be customized and integrated into various applications as per individual requirements.
