SpatialLM is innovative in three main dimensions:
- Data compatibility breakthrough: Distinguished from commercial software bundled with professional scanning equipment (e.g., Matterport), it can handle low-quality point clouds captured by consumer-grade devices such as cell phone cameras.
- Output semantics richness: While traditional tools (CloudCompare) mainly output geometric meshes, SpatialLM's LLM architecture can attach semantic labels and functional attributes such as "office chair - rotatable".
- Interactive flexibility: Support
--categoryParameters customize the detection category, e.g., only recognizing shelves and forklifts in warehouse scenarios, significantly reducing computational consumption.
Tests show that when dealing with 100 square meters of indoor scenes, SpatialLM1.1-Qwen version on RTX 4090 only takes 12 seconds to complete the extraction of architectural elements + 20 types of object detection, 8 times faster than the traditional pipeline.
