问 HN：高斯喷溅技术对分析普雷蒂之死有用吗？
2 分•作者: mdnahas•19 天前
现在，多个人用智能手机同时拍摄同一事件的情况已经很常见。我想到 Pretti 和 Good 的枪击案。我听说过高斯溅射技术，它能从多个摄像头的视频中构建 3D 场景。这项技术对分析这类事件有用吗？如果有用，有人能开发一个易于使用的开源工具吗？
我推测，这项技术可能对以下方面有用：（1）同步视频，（2）获取比单个摄像头更详细的信息，（3）追踪物体（比如 Pretti 的枪），这些物体能被多个摄像头捕捉到，以及（4）识别 AI 生成的视频。
对我来说，最后一点最重要。存在 AI 生成或修改事件视频的风险。在我看来，利用 N 个视频进行高斯溅射，应该能够检测出第 N+1 个视频与场景是否一致。
这有可能实现吗？

It is now common to have multiple people using their smartphones to video the same event. I'm thinking Pretti and Good's killings. I've heard of Gaussian Splattering, which constructs a 3D scene from multiple cameras. Is it useful for these analyzing these events? And, if so, can someone build an easy-to-use open source tool?<p>My speculation is that it would be useful to: (1) synchronize video, (2) get more detail than a single camera can get, (3) track objects (like Pretti's gun) that are seen by multiple cameras, and (4) identify AI generated video.<p>The last is most important to me. There is a danger of AI generated or modified video of an event. It seems possible to me that Gaussian Splattering from N videos will be able to detect if the N+1 video is consistent or inconsistent with the scene.<p>Is this possible?
