实验 36:A30 Surface-projected Lock Map

把 pixel depth residual 投影到 repair mesh surface,形成局部 mesh 改写约束

实验定位 表面级诊断正结果

A30 把 A29 的 pixel depth residual 投影回 repair mesh surface:对每个 repair 表面采样点,投影到 4 个输入相机,读取 residual delta,然后分类为 surface_improved、surface_conflict、surface_neutral 或 unobserved_closable。

结果非常强:gso_002 的 surface_improved=0.6621,surface_conflict=0.1609;gso_008 的 surface_conflict=0.7096,大面积红色冲突直接解释了 repair 为什么不能接受。

模块设计(Image-2 风格)

Legend

  • surface_improved:green: repair surface points whose projected depth residual improves
  • surface_conflict:red: repair surface points whose projected depth residual worsens
  • surface_neutral:gray: observed but neither clearly better nor worse
  • unobserved_closable:blue: not observed by valid VGGT/candidate common mask, potential closure region

Why It Matters

A30 已经把图像证据转成 mesh 表面证据。后续不必整 mesh 接受/拒绝 repair,而可以只保留 surface_improved,回退或重生成 surface_conflict,并只在 unobserved_closable 区域做水密闭合。
