dreamlake-mcap
收藏资源简介:
该数据集是Cognition pour-water (MCAP) — DreamLake可视化演示的一部分,包含三个真实双臂倒水记录的片段。每个片段被重新打包为独立的索引MCAP v1文件,采用zstd块压缩。数据集支持原地读取:摘要部分提供通道目录和时钟信息,消息数据仅在读取特定字段时通过范围请求拉取,适用于高效流式访问。数据集采用CC-BY-4.0许可证,主要应用于机器人学领域的双臂操作任务演示与可视化,尤其适用于倒水动作的分析与仿真。
This dataset is part of the Cognition pour-water (MCAP) — DreamLake visualization demonstration, containing three clips of real-world dual-arm water pouring recordings. Each clip is repackaged as an independent indexed MCAP v1 file with zstd block compression. The dataset supports in-place reading: the summary provides channel directory and clock information, and message data is fetched via range requests only when reading specific fields, suitable for efficient streaming access. The dataset is licensed under CC-BY-4.0, primarily used for demonstration and visualization of dual-arm manipulation tasks in robotics, especially for analysis and simulation of water pouring actions.

标签:robotics、mcap、dreamlake
内容概述: 该数据集包含三集真实双手机器人倒水操作的录制数据,每集为一个独立的索引MCAP v1文件,采用zstd压缩块存储。数据集采用原位读取方式(in-place read),摘要部分提供通道目录和时钟信息,消息数据仅在读取字段时通过范围请求(range request)按需拉取,适合可视化演示用途。
文件结构:
- 每集对应一个MCAP v1格式文件
- 使用zstd压缩块
- 文件内包含通道目录(channel catalog)和时钟(clock)摘要
- 消息数据支持按需读取(range request)
