| > 更新: 2026-03-19 |
|
|
| ## 1. 当前数据状况 |
|
|
| ### 1.1 总览 |
|
|
| 7 个数据集,24,448 条动作,79 种骨架(6 人类 + 73 动物)。 |
|
|
| | 数据集 | Motions | 骨架 | 已有文本 | 覆盖率 | 文本质量 | 需要标注 | |
| |--------|:-------:|:----:|:-------:|:------:|---------|:--------:| |
| | HumanML3D | 14,449 | 22j 人类 | 14,449 | **100%** | 高——人工多条标注 | 0 | |
| | Bandai Namco | 3,053 | 21j 人类 | 3,053 | **100%** | **低**——模板句,L1级 | **需升级** | |
| | CMU MoCap | 2,496 | 31j 人类 | 2,301 | 92% | **低**——CMU官方索引直接拼接 | **195 + 升级** | |
| | Mixamo | 2,453 | 67j 人类 | 0 | **0%** | 无 | **2,453** | |
| | Truebones Zoo | 1,110 | 25~143j 动物×73种 | 888 | 80% | 中——自动生成 species+action | **222 + 审校** | |
| | 100Style | 810 | 23j 人类 | 810 | **100%** | **低**——模板句,L1级 | **需升级** | |
| | LAFAN1 | 77 | 22j 人类 | 77 | **100%** | **低**——仅动作类型 | **需升级** | |
|
|
| ### 1.2 现有文本样例及问题 |
|
|
| **HumanML3D (OK, 不需要动)**: |
| ``` |
| "a man kicks something or someone with his left leg.|||the standing person kicks |
| with their left foot before going back to standing position.|||a person kicks with |
| their left leg.|||a person standing kicks their left foot forward." |
| ``` |
| - 多条标注(3-5 条),自然语言,L2-L3 级别 |
|
|
| **Bandai Namco (需升级)**: |
| ``` |
| "A person performs a active bow." ← 语法不通,模板生硬 |
| "A person performs a angry bow." ← 缺冠词、无细节 |
| "A person performs walk turn left." ← 不自然 |
| ``` |
|
|
| **CMU MoCap (需升级)**: |
| ``` |
| "A person performs: playground - forward jumps, turn around." ← 原始索引直接拼接 |
| "A person performs: walk." ← 太简单 |
| ``` |
| 195 条完全无文本(CMU 索引中缺失或标注为 "Unknown" 的条目) |
|
|
| **100Style (需升级)**: |
| ``` |
| "A person does a backward run in a aeroplane style." ← 模板句,aeroplane style 含义不明 |
| "A person stands idle in a monk style." ← style 语义对人来说不直观 |
| ``` |
|
|
| **LAFAN1 (需升级)**: |
| ``` |
| "A person performs aiming." ← 极度简单,无任何细节 |
| "A person performs fight." |
| ``` |
|
|
| **Mixamo (完全缺失)**: |
| - 文件名是哈希值(如 `00041fd3325430d72c5a947e1171de3b.bvh`),无任何语义信息 |
| - **必须通过观看 GIF 渲染来标注** |
|
|
| **Truebones Zoo (部分缺失)**: |
| ``` |
| "An alligator sways its head and wags its tail.|||An ambush predator sways its |
| head and wags its tail.|||An animal sways its head and wags its tail.|||" |
| ``` |
| - 已有 888/1110 条,自动生成,质量中等 |
| - 缺失 222 条(主要是 Idle、TPOSE 等难以描述的姿态) |
|
|
| ### 1.3 文本存储位置 |
|
|
| 文本**存在 motion npz 文件的 `texts` 字段里**: |
| ```python |
| data = np.load("data/processed/{dataset}/motions/{id}.npz") |
| texts = str(data["texts"]) # 多条文本用 "|||" 分隔 |
| ``` |
|
|
| 另有结构化标签存在 `data/processed/{dataset}/labels.json`。 |
|
|
| ### 1.4 可视化文件位置 |
|
|
| 每条 motion 都有渲染好的 GIF 和静态图,用于标注时参考: |
| ``` |
| /scratch/ts1v23/workspace/motion_representation_study/data/processed/{dataset}/renders/ |
| {id}.gif ← stick figure 动画 |
| {id}_overview.png ← 多视角静态截图 |
| ``` |

|
| ## 2. 标注任务 |
|
|
| ### 2.1 任务分级 |
|
|
| | 优先级 | 任务 | 数据集 | 条数 | 方式 | |
| |:------:|------|--------|:----:|------| |
| | **P0** | 从零标注 | Mixamo | 2,453 | 看 GIF 写描述 | |
| | **P1** | 补缺 + 审校 | Truebones Zoo | 222 缺失 + 888 审校 | 看 GIF 补写/修正 | |
| | **P1** | 补缺 | CMU MoCap | 195 | 看 GIF 写描述 | |
| | **P2** | 升级文本 | Bandai Namco | 3,053 | 看 GIF,替换模板句 | |
| | **P2** | 升级文本 | 100Style | 810 | 看 GIF,替换模板句 | |
| | **P2** | 升级文本 | LAFAN1 | 77 | 看 GIF,替换模板句 | |
| | - | 不需要 | HumanML3D | 0 | 已有高质量标注 | |
|
|
| ### 2.2 P0/P1: 从零标注或补缺 |
|
|
| 打开对应的 GIF 文件,写 **1-2 句英文描述**。 |
|
|
| **描述原则**: |
| - 写 **"做什么"**,不写 **"怎么做"** |
| - 以 "A person..." 或 "A [animal]..." 开头 |
| - 包含:动作主体 + 核心动作 + 方向/速度/风格(如适用) |
| - **不要提及关节名、骨骼数量、骨架结构** |
|
|
| **好的描述**: |
| ``` |
| A person jogs forward and then slows to a walk. |
| A person throws a punch with their right hand then steps back. |
| A dog runs forward and leaps over an obstacle. |
| An eagle spreads its wings and takes off from the ground. |
| ``` |
|
|
| **差的描述**: |
| ``` |
| ❌ "Walking." → 太短,缺主体 |
| ❌ "The skeleton moves forward." → 提到了骨架 |
| ❌ "Left knee bends 45 degrees." → 关节级细节 |
| ❌ "A 67-joint character performs motion." → 技术信息 |
| ❌ "一段动画" → 无信息量 |
| ``` |
|
|
| ### 2.3 P2: 升级已有模板文本 |
|
|
| 已有模板句需要**替换为自然语言描述**,不是在模板句上修改。 |
|
|
| | 原始模板 | → 升级后 | |
| |---------|---------| |
| | `A person performs a active bow.` | `A person bows energetically with a wide arm gesture.` | |
| | `A person performs walk turn left.` | `A person walks forward and makes a left turn.` | |
| | `A person does a backward run in a aeroplane style.` | `A person runs backward with both arms extended out to the sides like airplane wings.` | |
| | `A person performs aiming.` | `A person holds a steady aiming pose, looking forward with arms raised as if holding a rifle.` | |
|
|
| ### 2.4 多条描述 |
|
|
| 每条动作**至少写 2 条不同描述**,用 `|||` 分隔: |
| ``` |
| A person walks forward briskly.|||A person takes quick steps in the forward direction. |
| ``` |
|
|
| 用词不同但语义相同。参考 HumanML3D 的风格——同一动作由不同人描述。 |
|
|

|
|
| ## 3. 标注格式 |
|
|
| ### 3.1 交付格式 |

|
| ## 4. 标注工具 |
|
|
| ### 4.1 查看动作 |
|
|
| GIF 和概览图在: |
| ``` |
| /scratch/ts1v23/workspace/motion_representation_study/data/processed/{dataset}/renders/ |
| ``` |
|
|
| 用任何图片查看器打开 `.gif` 即可预览动作。如果 GIF 不够清晰,可以看 `_overview.png` 的多视角静态图。 |
|
|
| ### 4.2 按数据集分配 |
|
|
| 建议按数据集拆分给不同标注者: |
|
|
| | 标注者 | 数据集 | 条数 | |
| |--------|--------|:----:| |
| | A | Mixamo (前半) | ~1,200 | |
| | B | Mixamo (后半) | ~1,200 | |
| | C | Bandai Namco | 3,053 | |
| | D | CMU MoCap (195 缺失) + 100Style + LAFAN1 | ~1,082 | |
| | E | Truebones Zoo (222 缺失 + 888 审校) | ~1,110 | |
|
|
| ### 4.3 审校 Truebones Zoo |
|
|
| 对已有的 888 条 Zoo 文本,审校任务是: |
| 1. 打开 GIF |
| 2. 对比已有文本,判断是否准确 |
| 3. 如果描述有误或太泛(如 "An animal moves"),**重写** |
| 4. 如果描述正确,跳过 |
|
|
| --- |
|
|
| ## 5. 质量标准 |
|
|
| - [ ] 每条动作至少 2 条英文描述 |
| - [ ] 描述必须以 "A person..." / "A [animal]..." 开头 |
| - [ ] 描述不提及骨骼/关节/技术细节 |
| - [ ] `action_category` 全部填写 |
| - [ ] 动作与描述不匹配率 < 5%(抽样检查) |
| - [ ] Idle / T-Pose 也需要标注(如 "A person stands still in a neutral pose.") |
