了解视频的人数 [英] Know how many people are on a video

问题描述

所以，它是，我想从服务器获取一个摄像机视频流，并能够知道有多少人出现在它。

So there it is, I want to get a camera video stream from a server, and be able to know how many people appear on it.

我可以在服务器上安装任何操作系统（MAC，Windows，Linux），使用任何API（免费或付费）和任何语言（C ++，php等）这样做。

I can install any OS (MAC, Windows, Linux) on my server, use any API (free or paid) and any language (C++, php etc.) to do so.

我已经找到一些有趣的东西，如OpenCV，但我认为它更有用的面部识别比知道一个房间里的人数...

I already found some interesting things, such as OpenCV but I think it's more useful for face recognizing than to know the number of people in a room...

任何帮助将不胜感激：）

Any help would be appreciated :)

推荐答案

每个框架的基本统计导出：

Use a human detector applied on each frame for basic statistic exports:

OpenCV已经有一个：

OpenCV has one already:

http://docs.opencv.org/doc/tutorials/objdetect/cascade_classifier/cascade_classifier.html

所有你需要做的是用人体（_fullbody.xml）替换面部模型：

All you have to do is replace the face model with a human body (_fullbody.xml):

您现在可以导出一些统计信息，例如每帧人物的方式。要查找序列中出现了多少个唯一的个人，您需要一个跟踪器。从那里的事情变得更加困难。你必须找到适合你的情况。提示：google为多目标跟踪代码或类似。

You can now export some statistics such as how people per frame there are. To find how many unique individuals appeared in a sequence, you'll need a tracker. From there things get more difficult. You'll have to find something that suits your case. Tip: google for "multi-target tracking code" or similar.
