Since its initial release in August 2021, EasyAR Mega has undergone multiple major version iterations, consistently focusing on its core VPS (Visual Positioning System) capabilities. It has now become the most trusted platform in the field of large-scale AR for developers and clients. This trust is no coincidence but stems from the EasyAR team's firm belief in the future of mixed reality and their dedication to refining the product to perfection. Many wonder: What makes EasyAR Mega stand out? The answer lies in six key advantages—the "Six Meridians Divine Sword" that empowers developers to navigate the industry with ease, showcasing its robust capabilities as a city-scale spatial computing open platform.

For a quick overview, here are the six core advantages. Subsequent articles will delve into each in detail, providing a comprehensive understanding of each "sword's" prowess.

Part 01. Ultra-Large Scale - Urban-Level Spatial Modeling Capability

1. Extra-Large Single-Area Coverage: It can complete the collection of a single area larger than 100,000 m² in just 2 hours, covering most application scenarios.
2. Efficient Collection Process: The entire process is completed in one go, requiring only a consumer-grade panoramic camera; no mobile phones, calibration boards, or multiple rounds of collection are needed.
3. Diversified Collection Methods: In addition to panoramic cameras, it also supports mobile phones, laser scanners, drones, and other solutions simultaneously.
4. Million-Level Automatic Stitching: The system automatically stitches multiple areas to generate a globally consistent model with a scale of over one million m², no manual alignment required.
5. Day-Night Data Fusion: Supports the fusion of daytime and nighttime data, ensuring reliable use at night.
6. High-Definition Model: The Mesh has rich details and clear textures, which can not only restore the texture of tree trunks but also identify store signs, facilitating fine occlusion and content creation.
7. Complete Structure Output: Synchronously generates data such as Mesh (supporting LOD), textures, trajectories, and panoramas, providing convenience for creation, preview, and testing.

Part 02. High-Precision Experience - High-Accuracy VPS

1. Centimeter-Level Positioning in Routine Scenarios: Centimeter-level accuracy can be achieved in typical urban building environments.
2. High Reliability in Extreme Scenarios: Stable positioning is achievable in scenarios such as long-distance views, river views, night scenes, and environments with repeated structures.
3. AR Navigation Adapted to Complex Locations: It can easily implement navigation in high-challenge scenarios such as hospitals, airports, and parking lots.
4. Rapid Positioning Response: The cold start positioning time for the first frame reaches sub-second level.
5. End-Cloud Fusion: The algorithm integrates cloud positioning and terminal real-time pose to resist network fluctuations.
6. Long-Term Stability: The content is consistently aligned with the environment for a long time, without jitter or drift.

Part 03. Worry-Free Creation - Complete Toolchain

1. What-You-See-Is-What-You-Get Editor: Based on 1:1 Mesh, trajectories, panoramas, and other multi-view perspectives, maximizing editing efficiency.
2. 3D Road Network Editing: Built-in efficient road network tools to accelerate the implementation of AR navigation.
3. Remote Testing: Supports off-site testing, significantly reducing on-site testing costs.
4. Flexible API: Balances ease of use and depth, suitable for both beginners and complex needs.
5. Self-Service Process: The whole process from collection to launch is completed in one go, no manual intervention from EasyAR is required.
6. Data-Content Decoupling: Lightweight annotation enables cross-engine content sharing.

Part 04. Smooth Operation - Comprehensive Cloud Services and Operation & Maintenance Capabilities

1. No Worry About Scene Changes: Supports partial data updates, no modifications to online applications are needed.
2. Flexible Range Expansion: Capacity can be expanded at any time without affecting the original area.
3. Lossless Upgrade: The coordinate system remains unchanged, eliminating the need to reposition virtual content.
4. Stable and Reliable Services: The availability of online cloud services is guaranteed.
5. Elastic Scaling: Seamless scaling on the cloud side to cope with fluctuations in business volume.
6. Version Compatibility: Both the SDK and the cloud provide comprehensive compatibility and upgrade mechanisms.

Part 05. Open Ecosystem - Multi-Platform Compatibility and Interoperability

1. Mobile Terminals: Industry-leading Android adaptation rate.
2. AR/VR Glasses: Compatible with devices such as Apple Vision Pro, Pico, XReal, and Rokid.
3. Mini Programs: Fully supports WeChat and Alipay mini programs.
4. 3D Engines: Perfectly supports Unity, and is compatible with UE and self-developed engines (with successful cases).
5. Open Interfaces: Supports custom device expansion (with successful cases).

Part 06. Talent and Decision-Making - A Powerful Assistant for Management

1. Rapid Experience Evaluation: A large amount of ready-made data covers hundreds of locations across the country, which can be used out of the box to help you make quick decisions.
2. Sufficient Reserve of Developers: The community has complete tutorials and teaching materials, and the consistent SDK design over the years lowers the threshold for getting started.
