Researchers have introduced PinpointQA, a new benchmark designed to evaluate the spatial understanding capabilities of multimodal large language models (MLLMs) when processing indoor videos. The benchmark, built upon ScanNet++ and ScanNet200, features over 10,000 question-answer pairs across four difficulty levels, focusing on precise object localization and spatial description. Initial evaluations show a significant performance drop for current MLLMs on these tasks, particularly in structured spatial prediction, though supervised fine-tuning demonstrates potential for improvement.
