# Basic Specification

> Identification map is the cornerstone of the entire AR, and only when the identification information is added can the AR content be added. For the platform, 2D images are the most widely used type; the recognition of the picture will determine the recognition stability of the entire AR. If the recognition of the picture does not meet the standard, it may cause no recognition or difficulty in recognition Therefore, we have some necessary specifications for the image tracking applied in the platform.

* Supported format: jpg; 
* Size limit: 240(px) x 240(px) to 3000(px) x 3000(px); 
* File size limit: within 5M;

## 2. Cloud Recognition standards

When creating a new scene, select the scene type as \[WebAR Scene-Image Detection and Tracking] and \[WebAR Scene-Gyroscope/Cloud Recognition], first the standard for identifying the image should follow the cloud recognition standard.

For detailed specifications, please refer to:

• The best way to optimize

• How to make an identification map

## 3. Support tracking identification map standard

For the \[WebAR scene-image detection and tracking] scene with tracking identification maps, special specifications should also be followed: <https://www.yuque.com/kivicube/manual/tracking-marker>
