| Attribute |
Vehicle or LP parameter: brand, model, color, LP symbols, etc. |
| Base64 |
A standard for encoding binary data (in the context of the CARS API - images) using 64 ASCII characters. |
| Bounding Box (BBox) |
A rectangle that bounds the image space with a detected object (Vehicle, LP, pedestrian, animal). |
| CARS Analytics |
Subsystem for collecting, storing and displaying the results of the CARS API and CARS Stream operation through a web interface. |
| CARS API |
Subsystem for detection and recognition of vehicles and LPs attributes on images in real-time. |
| CARS Stream |
Subsystem for detecting and tracking vehicles, LPs, pedestrians and animals in the video stream and determining the best frames. |
| Classifier |
An object of the CARS API subsystem that recognizes one of the attributes of a vehicle or LP. |
| Detection |
Actions to determine areas of the image containing vehicle or LP. |
| Detector |
Algorithm for finding areas of the image containing vehicle or LP. |
| Exchangeable Image File Format (EXIF) |
A format that allows a user to add additional information (metadata) to images, commenting on this file, describing the conditions and methods of obtaining it, authorship, etc. |
| False negative detection |
Result of the detection when an object that is a vehicle or LP is not detected and not defined as a vehicle or LP. |
| False positive detection |
Result of the detection when an object that is not a vehicle or LP is detected and defined as a vehicle or LP. |
| Inference |
Image processing by a neural network and generation of results: coordinates of detections and the probability that the detection is an object of interest to us (vehicle, LP). |
| JavaScript Object Notation (JSON) |
A text-based data exchange format based on JavaScript. |
| License plate (LP) |
An individual alphanumeric designation assigned to a vehicle by a registration unit. |
| LUNA CARS |
A system designed for detection, tracking, recognition of vehicle and LPS attributes. The system consists of three subsystems: CARS Analytics, CARS API and CARS Stream. |
| Nginx |
A load balancer that allows you to distribute requests and responses between running copies of the CARS API and external systems. |
| Non-maximum suppression (NMS) |
Algorithm for determining the boundaries of objects in the image. |
| Redetection |
Repeated actions to determine areas of the image containing vehicle or LP. |
| Track |
Information about the position of the vehicle and LP in the sequence of frames. |
| Tracking |
The process of obtaining information about the position of the vehicle or LP on a sequence of frames. |
| Vehicle |
A technical device for the transport of people and/or goods, for which a special right is granted. |
