# OpenPose_Remapping for ComfyUI(骨骼重映射节点)
|
||
|
||
> ✨ A pose remapping node with support for joint locking, motion-aware scaling, and optional easing – perfect for animation refinement and mech rig control.
|
||
|
||
一个用于 **骨骼重映射（Skeleton Remapping）** 的 ComfyUI 节点，支持锁定躯干、末端关键点比例调节、帧间缓动过渡等功能，可用于高质量的人体姿态变换、动画平滑处理与机甲刚体控制。

# Pose Remapping 节点更新声明（7.25）
|
||
|
||
我们对以下节点进行了功能增强与优化，适配更灵活的人体姿态重建需求：
|
||
|
||
## ✅ 更新节点列表与说明
|
||
|
||
### 1. `ApplyPoseScalesToFrames`
|
||
- 支持按骨骼段进行 **比例缩放**
|
||
- 支持以参考帧为锚点进行 **全局位置对齐**
|
||
- 内置 **帧间平滑（EMA）**，减少动画抖动
|
||
|
||
### 2. `RenderKps`
|
||
- 支持批量渲染 **多帧姿态图像**
|
||
- 输出为 ComfyUI 兼容图像列表，可用于后续处理或预览
|
||
|
||
### 3. `ApplyPoseDiff`
|
||
- 应用两帧姿态间的 **差值位移**
|
||
- 可选择性缩放末端关节（腕、踝等）
|
||
- 支持缓动过渡，适合生成流畅的骨骼动画序列
|
||
|

|
||
|
||
这些节点可协同使用，完成从关键点解析、比例适配、动态迁移到图像渲染的完整流程。

|
||
|
||
✅ Skeleton Remapping – Automatically remap pose differences from the first frame to the entire animation
|
||
|
||
✅ 骨骼重映射：基于第一帧姿态差异，自动映射全帧姿态
|
||
|
||
✅ Motion-Aware Scaling – Dynamically scale movement on end-effectors (hands, feet) based on motion magnitude
|
||
|
||
✅ 支持比例缩放：末端关键点（手、脚）动作幅度可自适应
|
||
|
||
✅ Joint Locking – Keep shoulders and hips fixed to preserve torso stability
|
||
|
||
✅ 关节锁定：肩膀与髋部始终固定，保持身体稳定性
|
||
|
||
✅ Easing to Target Poses – Supports optional scaled_pose_diff + t to smoothly blend into global targets
|
||
|
||
✅ 动作缓动过渡：支持 optional scaled_pose_diff + t，实现向任意姿态过渡
|
||
|
||
✅ COCO‑18 & BODY‑25 Compatible – Auto-detects keypoint format
|
||
|
||
✅ 兼容 COCO‑18 与 BODY‑25：自动判断关键点格式
|
||
|
||
✅ Native ComfyUI Integration – Seamlessly works with ControlNet-style pose pipelines
|
||
|
||
✅ ComfyUI 原生节点，支持与 ControlNet pose pipeline 无缝集成
