动作捕捉需求 · 多种方式搬箱子Mocap Brief · Carrying a Box in Many Ways
01场地、箱子、演员Floor, box, performer
地上用胶带标出 START、A、B 三处;箱子长边(25 cm)与行走方向垂直,A、B 两处朝向一样。Tape START, A and B on the floor. The box's long side (25 cm) faces the performer, perpendicular to the walk, same at A and B.
- 箱子:25 × 15 × 20 cm(宽 × 深 × 高)硬纸箱,内加配重到约 1 kg;六个面都贴标记点(抱着时也能看到),做成一个刚体。
- Box: 25 × 15 × 20 cm (W × D × H) cardboard, weighted to about 1 kg; markers on all six faces so it stays tracked when hugged; one rigid body.
- 演员:一位,身高 1.60–1.80 m;紧身动捕服、平底鞋。
- Performer: one person, 1.60–1.80 m tall, tight suit, flat shoes.
- 每次开拍前:录一条 T 姿态校准,并记下身高、肩宽、臂长、腿长。
- Each session: one T-pose calibration take; note height, shoulder width, arm and leg length.
- 采样率:120 Hz 最好,不低于 60 Hz;手指可选。
- Rate: 120 Hz preferred, at least 60 Hz; fingers optional.
02一条完整录制长什么样What one full take looks like
- 开头、结尾都是同一个自然站姿(双脚与肩同宽、手臂自然下垂、面朝 B),各站稳至少 1 秒。
- Start and end in the same neutral stand (feet shoulder-width, arms down, facing B) and hold it at least 1 s.
- 箱子一开始放在地上的 A 点,最后放回地上的 B 点;全程不用桌子、架子。
- The box starts on the floor at A and ends on the floor at B; no tables or stands at any point.
- 朝着 B 直线走,身体朝前,不中途转身;速度自然。
- Walk straight to B facing forward, no turning on the way, natural speed.
- 走路时手不换位置、不调整抓法;箱子只靠手(或肩、手臂)带动,不要在身上滑。
- Keep the same grip while walking; the box moves only with the hands (or shoulder/arms), no sliding on the body.
- 失误(箱子掉、碰到人、走歪)就重拍这一条,不用剪。
- If something goes wrong (drop, bump, drift off line), just redo the take; no editing needed.
03每种方式拍三种片段Three take types per style
| 片段 | Type | 内容 | Content | 条数 | Takes |
|---|---|---|---|---|---|
| 完整 | full | 站 → A 点拿起 → 直走 3 m → B 点放下 → 站 | stand → pick up at A → walk 3 m → put down at B → stand | 2 | |
| 只拿起 | pickup | 站 → A 点拿起 → 原地站着抱住,静止 3 秒 | stand → pick up at A → hold the carry pose in place, still, 3 s | 1 | |
| 只放下 | putdown | 原地抱着静止 3 秒 → 放到脚前地上 → 站 | hold the carry pose still 3 s → put down in front → stand | 1 |
「只拿起」「只放下」两段的静止时刻,是我们之后接上不同行走路线的地方,所以静止要真静止。转弯、别的终点不用拍,我们自己生成。The still holds in pickup/putdown are where we attach generated walks, so please keep them truly still. Turns and other destinations are not needed; we generate those.

下面是机器人上的参考动作,由我们已有的数据重定向而来,帮你看清每种搬法长什么样。它们多数来自视频重建,质量不够,所以 A1–A8 也请用真人动捕重拍;A9–A12 我们还没有,是这次最想要的。Reference motions on the robot, retargeted from data we already have, so you can see what each style looks like. Most come from video reconstruction and are not clean enough, so please re-capture A1–A8 with real mocap; A9–A12 we do not have yet and want most.
05可选:脚下格子步法与身体打击乐(有时间再拍)Optional: floor-grid footwork and body percussion (if time allows)
用胶带贴一条 6 格的「绳梯」,每格 45 × 45 cm。听节拍器(90 和 120 拍/分钟)踩;不跳、不单脚跳。Tape a 6-square ladder, 45 × 45 cm each. Step to a metronome (90 and 120 bpm); no jumps or hops.
- 每条:站稳 1 秒 → 跟着节拍做约 8 拍 × 2 → 站稳 1 秒。
- Each take: stand 1 s → about 8 beats × 2 of the pattern → stand 1 s.
- 步法每种 4 条:两种速度 × 左脚先 / 右脚先。打击乐每种 2 条:两种速度。
- Footwork: 4 takes each (two tempos × left/right lead). Percussion: 2 takes each (two tempos).
- 同时录下节拍器声音,或记下节拍器开始的时间。
- Record the metronome audio, or note when it starts.
