修改概述:
AMASS 数据集包含 11313 条复杂运动序列(如跑跳、舞蹈),但针对简单运动(行走、站立、缓慢转身)的专项训练需求,需筛选低复杂度样本以提升训练效率与模型针对性。修改内容:
新增 scripts/data_process/filter_amass_simple.py,通过以下规则筛选简单运动:
关节角速度阈值(≤1.5 rad/s),排除快速运动;
身体重心位移速率(≤0.5 m/s),筛选缓慢移动;
动作类别标注(保留 “walking”“standing”“turning” 等简单类别)。
修改的详细描述
新增 phc/env/tasks/imitation_simple.py:
简化奖励函数:移除“失败恢复奖励”,仅保留“姿态拟合奖励”与“运动平滑奖励”;
调整终止条件:取消“姿态偏差阈值”的严格限制(从2.0放宽至3.0),适配简单运动的微小波动;
减少环境交互:关闭“随机外力干扰”(原用于复杂运动的抗干扰训练),专注姿态拟合
经过了什么样的测试?
