# TopoSlots 动作文本标注规范
> 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**
-**"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
每个数据集提交一个 JSON 文件:
```json
{
"000000": {
"texts_en": [
"A person bows politely with a slight forward lean.",
"A person performs a respectful bow, bending at the waist."
],
"action_category": "gesture",
"style": "active",
"notes": ""
},
"000001": {
"texts_en": [
"A person bows with an aggressive, exaggerated motion.",
"A person angrily bends forward in a forceful bow."
],
"action_category": "gesture",
"style": "angry",
"notes": ""
}
}
```
字段说明:

| `style` | 选填 | 风格标签(如 angry, sneaky, tired) |
| `notes` | 选填 | 标注备注(如 "动作不清晰"、"可能是两个动作拼接") |
### 3.2 动作类别

## 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.")
