Question

我构建了一个用于视线估计的应用程序，并使用UnityEyes工具来生成标记的合成眼图。每个.jpg图片文件都将与一个关联的.json元数据文件一起保存，该文件包含以下内容：

{ 
  "interior_margin_2d": [                     # Screen-space interior margin landmarks
    "(202.7042, 186.4788, 9.5512)", …         # x, y, z (can ignore z)
    ], 
  "caruncle_2d": [                            # Screen-space eye-corner (caruncle) landmarks
    "(191.9471, 175.4047, 9.6683)", …         # x, y, z (can ignore z)
    ], 
  "iris_2d": [                                # Screen-space iris boundary landmarks
    "(213.3930, 195.4109, 9.1951)", …         # x, y, z (can ignore z)
    ], 
  "eye_details": { 
    "look_vec": "(-0.3633, 0.0937, -0.9270, 0.0000)", # Gaze vector in camera-space (x, y, z)
    "pupil_size": "0.05249219",                       # Pupil size (arbitrary units)
    "iris_size": "0.9090334",                         # Iris size (arbitrary units)
    "iris_texture": "eyeball_amber"                   # Iris color
    }, 
  "lighting_details": …                       # Illumination details
  "eye_region_details": …                     # Shape PCA details
  "head_pose": "(351.2107, 161.3652, 0.0000)" # Euler angle rotation from camera to world
}

我的问题是如何在相机坐标中提取相对于头部姿势的注视矢量（即不依赖于头部姿势）？
