Introduction #
The dataset for Digital Breakthrough 2022: Ulyanovsk - Car Plate Detection is a collection of 482 meticulously labeled images with a specific emphasis on detecting a car’s plate. Embedded within the Ulyanovsk region (Russia) AI competition, this dataset presents an intriguing challenge for participants: devising an algorithm for real-time assessment of distances between cars depicted in various photos. The primary goal is to integrate this algorithm into navigation systems, serving as a precautionary tool to alert individuals about unsafe distances, thereby advocating and bolstering road safety standards.
About Digital Breakthrough: Season AI (Ulyanovsk Region)
According to the press service of the Moscow Traffic Police, by the end of 2021, non-compliance with the distance between cars has become the most dangerous violation. It is because of non-compliance with the safe distance to the car in front that people most often die and get into accidents on the roads.
Maintaining a safe distance from the vehicle in front is one of the important criteria for road safety. In real-time, such a parameter cannot be monitored with the help of surveillance cameras, and it is also impossible to estimate what distance the driver observes while driving around the city. To control safe driving, a solution is needed that will be able to track the distance between cars in real time. This will reduce the number of accidents and save the lives of drivers and passengers.
The participants of the championship are faced with the task of developing an algorithm that allows determining the distance to the car in front in real-time, using a dataset of photos of cars from different distances. Subsequently, this algorithm can be used in navigation systems to warn of a dangerous approach and to monitor compliance with the distance.
Author’s solution
The author’s solution is based on two datasets:
- Digital Breakthrough 2022: Ulyanovsk - Car Plate Detection (current)
- Digital Breakthrough 2022: Ulyanovsk - Car Object Detection (available on DatasetNinja)
The baseline provided by the organizers of the championship was taken as the basis of the solution, which was improved, namely, in addition to detecting the car, the number, and the car-mating badge were also detected, which gave a greater increase in speed. Additional models were retrained on the competition data train (manual marking using an online service makesense.ai ) using the YOLOv5 (YOLOv5m6) model. CatBoostRegressor with improved parameters was used to predict the distance.

GitHubSummary #
Digital Breakthrough 2022: Ulyanovsk - Car Plate Detection is a dataset for an object detection task. Possible applications of the dataset could be in the safety industry.
The dataset consists of 482 images with 482 labeled objects belonging to 1 single class (plate).
Images in the Digital Breakthrough 2022: Car Plate dataset have bounding box annotations. All images are labeled (i.e. with annotations). There is 1 split in the dataset: train (482 images). The dataset was released in 2022 by the Government of the Ulyanovsk Region and NordClan.
