SLAM System Pipeline

Our method performs real-time SLAM by fusing synchronized inputs from a multi-camera rig into a unified 3D Gaussian map. It first selects keyframes and estimates depth and normal maps for each camera, then jointly optimizes poses and depths via multi-camera bundle adjustment and scale-consistent depth alignment. Refined keyframes are fused into a dense Gaussian map using differentiable rasterization, interleaved with densification and pruning. An optional offline stage further refines camera trajectories and map quality. The system supports RGB inputs, enabling accurate tracking and photorealistic reconstruction.

| Problem | Solution | |--------|----------| | “Software install failed” | Wrong model or region code. Download correct Cxxx version. | | Phone stuck in eRecovery | Use HiSuite’s “System Recovery” mode. | | No OTA updates | Huawei servers may be offline for older models. Use manual dload. | | Downgrade from EMUI 10 to 9 | Must wipe data and use FullOTA-MF for EMUI 9.1. |

Before you start the update process, make sure to:

This method requires an unlocked bootloader and advanced tools (like fastboot commands or specific service boxes like UMT/Chimera). As this is the LX3A (LATAM) model, bootloader unlocking codes are difficult to obtain from Huawei directly now.

If you need recovery firmware (e.g., after bricking, bootloop, or downgrade), use trusted sources:

Analysis of Single-Camera and Multi-Camera SLAM (Tracking)

In this section, we benchmark tracking accuracy across eight driving sequences from the Waymo dataset (Real World). MCGS-SLAM achieves the lowest average ATE, significantly outperforming single-camera methods.

We further evaluate tracking on four sequences from the Oxford Spires dataset (Real World). MCGS-SLAM consistently yields the best performance, demonstrating robust trajectory estimation in large-scale outdoor environments.
