Exploring semi-automated offside technology

SAOT

I think Serie A introduced semi-automated offside technology (SAOT) during the 2022-23 season, starting in January 2023 after the Supercoppa. Champions League also uses SAOT, and as of the 2023-24 season, Serie A is utilizing it too. The technology employs 12 cameras to gather 29 data points per player at 50 fps to determine the kick point. However, errors can still occur, like misalignment due to ball occlusion or camera calibration issues. It's interesting to see how these details affect offside decisions!Discussing offside technology variations

It seems the EPL switched to thicker lines and is planning to adopt semi-automated offside technology (SAOT) for the 2024-25 season, while Serie A already uses it and displays 3D renders. However, Chinese broadcasts might show differing 2D lines. There are potential points of contention regarding offside decisions, like frame selection, defining body parts, and the perspective of broadcast angles. I can suggest checking specific moments or comparing against defenders, but since I don’t have video, I can only provide a general explanation.

Is the user looking for a broader explanation of offside and VAR, or do they want me to analyze a specific clip?Analyzing VAR and SAOT

It’s common for VAR offside lines to look off, mostly due to perspective differences and the definitions of the frame when the ball is touched or body parts involved. Possible solutions could include reliable SAOT 3D renders or official explanations. If SAOT was used, it’s generally more dependable; if it’s manual, errors may occur.

I should suggest that if the user can share screenshots or videos, I can annotate them frame by frame. Let’s keep it straightforward!

确实很容易让人觉得“划线不对”。越位判定里,肉眼看到的和VAR用的数据常常不是一回事,常见原因有:

  • 触球帧选择:越位要以传球者“真正触球”的那一帧为准。球被压扁/遮挡时,人工或算法可能提前/滞后1–2帧,就足以改变结论。
  • 身体部位定义:只计算可得分的部位(头、躯干、腿、脚,不含手臂)。比如进攻者“腋下/肩胛”的最前端超过防守者“脚尖”,即算越位,这和观众直觉不同。
  • 3D→2D投影误差:VAR会把球员、草坪做三维建模后再投到地面基准线;电视转播画面的透视线条是“看起来对齐”,但和VAR的3D基准并不等价。
  • 相机/镜头与球场标定:标定点、镜头畸变、球场微小坡度都会影响“线”落在地面的精确位置。
  • 防守者离地细节:防守者脚跟离地、脚尖悬空等,最前端可能不是你以为的那一点。
  • 线宽/容差策略:不同联赛有不同容差(线宽/合并线),有时看上去“差不多平行”,但技术标准仍判定越位。

关于这场:如果是意甲,多数比赛已使用半自动越位技术(SAOT,基于多机位+骨骼点的3D重建),原则上比人工划线更稳定,但仍可能在触球帧选择、遮挡或少数标定场景下引发争议。赛后通常会有一张官方3D示意图和技术说明,能看出认定的两个人体参考点与投影基线。

你要不要贴一张判罚时刻的截图或短视频片段?我可以按规则逐帧标注:选触球帧、标出双方可得分部位的最前端、说明为什么会与转播“看起来”不一致。
