  1. 红色线条是指的红色方框?那是 google mediapipe 的 roi 绘制,我在外部无法控制,除非修改 google 代码,你可以试试更改绘制风格 Holistic 组件上的 Annotation 样式 (OverlayAnnotationsVideoDisplay 这两个属性),或者干脆不显示追踪线条。

参考: https://opensource.labijie.com/Mediapipe4u-plugin/mocap/quick_start/texture_display.html

  1. 脚会跳动原因很多,关注这些点:
  • 算解评分阈值(大概率是这个原因,你如果需要全身动补建议评分设置为 0, 默认 0.5 )
  • 是否校准了一个错误的姿势(你的场景可能需要关闭姿势校准,参考这个文档
  • 建议开启脊柱旋转模式稳定脚踝
  • 你如果不需要弯腰,可以锁定 body 旋转轴,例如,禁止 pitch (Pose Solver 节点上的 UpperBodyLock 属性)

需要注意,Overlay 如果使用 Holistic 帧率会下降 5~6 帧,默认是 Pose Tracker ,几乎不会影响帧率

把overlay annotations改成holistic tracking后UI里的红线消失了。请问算解评分阈值是在哪里调?

改了角色蓝图里MediaPipe Pose Solver的alpha和smooth值为0没有效果

就是 MinPoseScoreThresh, 关闭姿态校准,禁用 fix Mediapipe 试试
