M3SunAgent Unifies Depth Estimation and 3D Grounding with LLM Planner

By PulseAugur Editorial · [1 sources] ·

Researchers have introduced M3SunAgent, a novel unified agent designed for monocular 3D spatial understanding. This agent utilizes a large language model as a task planner to coordinate various tools for metric depth estimation and 3D visual grounding. For depth estimation, it employs an object detector and a depth estimation tool, achieving a $\delta < 0.25$ error rate for 52.61% of predicted instances. In 3D visual grounding tasks, M3SunAgent integrates a vision-language model with back-projection and dimension-lifting tools, reaching a 3D mIoU of 41.73%, which surpasses the current state-of-the-art MonoVLM by 3.62%. A new benchmark dataset, M3Sun Instance (M3SI), has also been created to evaluate these capabilities. AI

IMPACT This unified agent approach could streamline 3D spatial understanding for embodied AI systems by integrating disparate tasks.
