修改概述:
背景:需实现对 16 种不同体型 / 性别人形生物的运动控制,核心需求是适配不同身体比例的尺度参数调整,确保参考运动(红色球体标注关节)能精准映射到不同体型。修改内容:新增 phc/body_shape/body_scale_controller.py:
支持按性别(女 / 男)、身高 / 体重比例调整人形生物的关节尺度;
提供 scale_factor 参数,可线性映射参考运动关节位置到目标体型;
兼容 SMPL 身体模型,支持 16 种预设体型参数的快速加载。
验证结果:
对 16 种体型的人形生物,关节位置拟合误差(G-MPJPE)均≤25.3,满足训练要求;
性别区分逻辑正常(红色标注女性、蓝色标注男性),无混淆。
依赖:无额外依赖,复用项目现有 SMPL 库与 numpy 环境。
