Elevate Your Operations with SPICD-Net: Precision Indoor Change Detection
SPICD-Net offers a lightweight Siamese PointNet for indoor 3D change detection using synthetic anomaly training, eliminating manual annotation. It achieved 0.84 F1-score with zero false positives in no-change baseline, and a 22.4s inference time on consumer-grade hardware. Critical for robust autonomous indoor navigation, it excels in detecting additions and movements but shows sensitivity to point removals and registration errors, highlighting its practical utility under specific operational prerequisites.

Problem Statement
Autonomous mobile robots require up-to-date environmental maps for navigation and safety. Indoor environments frequently change (furniture, equipment, obstructions), leading to localization and path planning failures. Manual annotation of changes for training is impractical, and existing methods often focus on outdoor scenes or require heavy computational resources.
Proposed Solution
SPICD-Net, a lightweight Siamese PointNet framework, is proposed. It uses synthetic anomaly injection for training, a three-class Siamese formulation (no-change, changed, geometrically inconsistent), and an optional Chamfer-statistics branch for explicit geometric cues. It’s designed for consumer-grade hardware and annotation-free indoor deployment.
Key Innovation
The core innovation lies in its end-to-end, annotation-free training pipeline using pre-FPS anomaly injection for realistic synthetic data. This, combined with a three-class Siamese formulation and stochastic-gated Chamfer statistics, allows for robust indoor change detection on resource-constrained platforms without manual labeling, a significant practical advantage.

Real-World Validation: Unseen Room Scenario
In a limited real-world test in an unseen room, SPICD-Net successfully detected all introduced physical changes (Recall = 1.000) with a Precision of 0.583. While the detection threshold needed adjustment (from 0.17 to 0.50), this demonstrates the framework's capability to generalize geometrically beyond its training environment and identify genuine scene alterations.
Outcome: Successful detection of all real changes in an unseen environment, albeit with increased false positives requiring threshold re-optimization.
