1 # V9P3R2 跑后再次消融 2 3 对照均为原完整序列；与 V9P3R2 使用同一随机种子、锁定运行环境和原始模型输出。no_scene 改表面约束，no_ownership 改归属有效位；常规控制只改一个配置字段，no_partial_rotation_copy 使用另存源码只移除邻帧旋转复制。统计不是3D真值。 4 5 | 序列 | 关闭项 | 同观测重投影 P95：R2→对照 | 超60°帧槽位：R2→对照 | 网格相交槽位：R2→对照 | 6 |---|---|---|---|---| 7 |0907_1210_5cam__0907_1210_5cam__clip_11_action|no_boundaries|18.67→18.67|0→0|98→98| 8 |0907_1210_5cam__0907_1210_5cam__clip_11_action|no_palm_guard|18.67→14.73|0→0|98→62| 9 |0907_1210_5cam__0907_1210_5cam__clip_11_action|no_partial_init|18.67→18.28|0→0|98→97| 10 |0907_1210_5cam__0907_1210_5cam__clip_11_action|no_scene|18.67→18.67|0→0|98→98| 11 |0907_1443_5cam__0907_1443_5cam__clip_15_action|no_palm_guard|2.90→2.87|0→0|94→93| 12 |0907_1443_5cam__0907_1443_5cam__clip_15_action|no_partial_init|2.90→2.95|0→0|94→96| 13 |0907_1443_5cam__0907_1443_5cam__clip_18_action|no_boundaries|3.15→3.15|1→1|145→145| 14 |0907_1443_5cam__0907_1443_5cam__clip_18_action|no_ownership|3.15→3.15|1→1|145→145| 15 |0907_1443_5cam__0907_1443_5cam__clip_18_action|no_palm_guard|3.15→3.15|1→2|145→140| 16 |0907_1443_5cam__0907_1443_5cam__clip_18_action|no_partial_init|3.15→3.10|1→0|145→145| 17 |0907_1443_5cam__0907_1443_5cam__clip_18_action|no_scene|3.15→3.13|1→0|145→140| 18 |0910_02_155724_5cam|no_palm_guard|4.44→4.80|32→34|1992→1992| 19 |0910_02_155724_5cam|no_partial_init|4.44→5.06|32→35|1992→2242| 20 |0910_03_160411_5cam|depth_temporal_20|4.64→4.55|17→15|1936→1934| 21 |0910_03_160411_5cam|no_boundaries|4.64→4.77|17→18|1936→1950| 22 |0910_03_160411_5cam|no_ownership|4.64→4.64|17→18|1936→1882| 23 |0910_03_160411_5cam|no_palm_guard|4.64→4.76|17→10|1936→1948| 24 |0910_05_161036_5cam|no_palm_guard|6.76→6.86|19→30|2559→2562| 25 |0910_05_161036_5cam|no_scene|6.76→6.86|19→14|2559→2500| 26 |0910_10_163938_5cam|no_palm_guard|7.37→7.02|34→42|1282→1275| 27 |0910_10_163938_5cam|no_partial_init|7.37→7.77|34→43|1282→1295| 28 |0910_10_163938_5cam|no_scene|7.37→7.43|34→30|1282→1224| 29 |0910_11_164405_5cam|no_palm_guard|4.99→5.96|44→47|2061→2077| 30 |0910_11_164405_5cam|no_partial_init|4.99→4.97|44→47|2061→2060| 31 |0910_11_164405_5cam|no_partial_rotation_copy|4.99→4.97|44→44|2061→2064| 32 |0910_11_164405_5cam|no_scene|4.99→4.92|44→51|2061→2013| 33 |0910_12_170126_5cam|no_boundaries|3.35→3.44|38→45|3029→3039| 34 |0910_12_170126_5cam|no_palm_guard|3.35→3.63|38→41|3029→3050| 35 |0910_16_173314_5cam|no_palm_guard|9.18→9.05|5→6|1372→1383| 36 |0910_16_173314_5cam|no_partial_init|9.18→9.80|5→5|1372→1375| 37 |0910_17_173551_5cam|depth_temporal_20|10.05→9.01|17→19|2514→2580| 38 |0910_17_173551_5cam|no_depth_temporal|10.05→8.68|17→22|2514→2619| 39 |0910_17_173551_5cam|no_palm_guard|10.05→10.09|17→17|2514→2515| 40 |0910_17_173551_5cam|no_scene|10.05→9.71|17→21|2514→2527| 41 42 额外控制包括 `no_partial_rotation_copy`（只移除部分遮挡初始化中的邻帧旋转复制）和 `no_depth_temporal` / `depth_temporal_20`（深度时序权重200→0/20）。前者是保存完整受控源码的单行机制干预，其余是一个配置字段干预。详见 [坏结果与分析](BAD_RESULTS_ZH.md)。
