- ABot-Recon 是高德 CV Lab 开源的实时流式 3D 重建模，只靠最近 12 帧的 KV 缓存上下文窗口，配合上逐帧估计相机坐标系点图和上一帧的位姿串成轨迹，再把局部点图沿轨迹维护在同一坐标系就能持续生成可更新的三维点云地图。性能方面在 H100 GPU 上 504x280 的分辨率跑 KITTI-02 能到 24.45 FPS。爱芯元智已经把 ABot-Recon 移植到了…

- 长视频3D重建一定要不断累积长期记忆吗？ABot-Recon换了个思路：只保留固定12帧局部上下文。它缓存前11帧的KV特征，逐帧预测点图与相邻位姿，再连续组合成全局轨迹和点云。这样内存和单帧计算量不随视频变长；重访区域还能选用回环优化。关键启发是：长时序任务未必先堆全局状态，也可以把局部预测做稳，再显式组合。
