推文介绍了Cambrian-P，这是一个原生集成相机位姿的多模态大语言模型。其核心观点是，相机位姿是一种易于获取且足以支撑鲁棒视频理解的最小3D信号。通过联合建模视频帧与位姿，模型能将图像序列转化为全局结构化的表示。引用推文指出，当前多模态大语言模型在识别视频活动方面表现优异，但对视频中的空间结构及自主体/物体动态的理解仍然不足，而相机位姿信息是弥补这一差距的关键缺失环节。

📸latest in our cambrian series: cambrian-p, p for pose.
i think pose is probably the minimal sufficient 3d signal (and it’s easy to get!) that we need for robust video multimodal models -- jointly modeling frames and pose turns image sequences into a globally grounded structure.
Camera pose matters for video understanding! Today's MLLMs excel at recognizing activities, but still struggle with the underlying space and ego/object dynamics in video. We trace this gap to a missing piece: camera pose. Introducing Cambrian-P: a multimodal LLM natively grounded in camera pose. (1/n)在 X 查看被引用的帖子
