Clarifying SAOT in Serie A
I'm exploring the introduction of SAOT in Serie A. I recall that SAOT was implemented mid-season in 2022-23 and had actually debuted in World Cup 2022. It seems that Serie A officially introduced it for the 2023-24 season starting in January 2023. Udinese plays in this league, suggesting they’re using this tech without manual lines, relying on a 3D skeletal system with multiple cameras. However, I question if the ball chip was included since Serie A uses a different ball. Overall, leagues differ in their implementation, which makes things tricky!Analyzing Offside Decisions
I can suggest some key points for the user to check regarding offside situations: freeze-frame, consider the second-last defender, and the placement of feet. It's important to note that broadcast replays might show different lines compared to VAR. If the user seeks confirmation on a decision's correctness, they should provide a video or images for better analysis. Requesting details like match date, competition, timestamp, or screenshots could help clarify issues. I'll mention that if SAOT isn’t used, there are margins of error with league-imposed tolerances!Understanding Offside Technology
It's interesting to note that some leagues use "thicker lines" for offside decisions. I should consider frame rates too; for instance, at 50 fps, you have about 20 ms per frame, and with a sprint speed of 8 m/s, it results in 16 cm of movement per frame. Minor differences can significantly impact decisions. VAR determines the "point of contact" for passes, and factors like camera angles and occlusion can lead to errors. I'll ask the user for any screenshots or replay links for further analysis.
看到了,类似的争议常见。没视频我没法判定这球对/错,但说说VAR越位“划线”常见出问题的点,帮你对照回放自查:
你可以这样快速核对:

如果你有该球的截图或回放链接(最好是正回防的门线/横移机位),发来我帮你逐帧标注并给出更明确判断。
