Augmented Reality (AR) works by overlaying virtual content onto the real world in real-time. The process typically involves the following steps:
- Sensor Data Capture: AR devices, such as smartphones or AR headsets, capture data from various sensors like cameras, gyroscopes, accelerometers, and depth sensors. This data helps to understand the user's physical environment and movements.
- Environment Mapping: The AR system creates a digital representation of the real-world environment by mapping and tracking physical objects, surfaces, and features. This mapping helps to anchor virtual content accurately in the real world.
- Computer Vision and Image Processing: Computer vision algorithms analyze the sensor data to identify and track key visual markers, patterns, or features in the environment. This allows the AR system to understand the user's position, orientation, and interactions within the real world.
- Virtual Content Generation: Based on the information gathered from the sensors and environment mapping, the AR system generates or retrieves appropriate virtual content, such as images, 3D models, videos, or text. This content is aligned and positioned correctly within the user's view, considering the user's perspective and the physical environment.
- Rendering and Display: The AR system renders the virtual content and combines it with the live video feed from the device's camera or the user's view. The resulting augmented view is then displayed on the device's screen or through an AR headset, allowing the user to see the real world overlaid with virtual elements.
- Real-Time Interaction: Users can interact with the virtual content and the real world through various input methods, such as touch gestures, voice commands, or motion tracking. The AR system responds to these interactions, updating the virtual content or triggering specific actions accordingly.

The differences between marker-based and markerless Augmented Reality (AR) primarily lie in how the virtual content is anchored and aligned with the real world. Here's a breakdown of each approach:
Marker-Based Augmented Reality:
- Marker-based AR relies on the use of predefined markers, also known as fiducial markers or triggers. These markers are typically visual patterns, such as QR codes or specific images with distinct features.
- The AR system uses these markers as reference points to detect and track their position and orientation in the camera view.
- When the markers are recognized by the AR system, virtual content, such as 3D models, animations, or information overlays, is superimposed onto the markers' location in real-time.
- Marker-based AR provides accurate and stable tracking, making it suitable for applications where precise alignment of virtual content with specific markers is required.
Markerless Augmented Reality:
- Markerless AR, also known as location-based or feature-based AR, does not require predefined markers for tracking.
- Instead, markerless AR relies on the recognition and tracking of natural features in the environment, such as objects, surfaces, or landmarks.
- Computer vision algorithms analyze and match features, such as corners, edges, or textures, in the camera view with previously mapped or learned features to estimate the camera's position and orientation.
- Virtual content is then overlaid onto the recognized surfaces or objects, aligning with the real-world scene.
- Markerless AR offers more flexibility in terms of interaction with the environment, as it can work on any suitable surface or object without the need for specific markers.
Key differences between marker-based and markerless AR include:
- Tracking Method: Marker-based AR uses predefined markers as reference points for tracking, while markerless AR relies on natural feature tracking in the environment.
- Flexibility: Marker-based AR requires specific markers for content alignment, while markerless AR can work on various surfaces or objects without the need for predefined markers.
- Accuracy and Stability: Marker-based AR typically provides more precise and stable tracking, as markers provide reliable reference points. Markerless AR may have slightly less accuracy, depending on the quality of feature detection and tracking algorithms.
- Setup and Preparation: Marker-based AR requires the creation or placement of specific markers in the environment. Markerless AR does not require any specific setup or preparation, making it more convenient for spontaneous AR experiences.
