人数图像处理应用程序 [英] Headcount image processing application

问题描述

我需要编写代码来计算在特定地点(会议，社交聚会)发现的人数.
我必须上传图片，系统应该计算当时的人数.
我该如何进行?
我正在将opencv与python一起使用.
我曾考虑过将图像转换为灰度(减少颜色信息)
然后应用阈值化.
检测椭圆形..但是如何真正做到这一点呢?
thnx

i need to write a code for counting the number of people found at a particular place (Meetings, social gathering).
i have to upload the picture and the system should count the number of people present at that time.
how can i proceed?
i am using opencv with python.
i have thought of converting the image to grayscale (reducing color info)
then apply thresholding.
detect oval shapes..but how to really go about this?
thnx

推荐答案

近似值是多少?无需计算每个头部，只需确定填充的区域(实际尺寸)，然后计算样本区域的头部密度即可.对于不是鸟瞰并且出到地平线的图片，这可能会更准确.它也可以计算被遮挡但假定有人满的区域(例如阴影，帐篷等)的头数.

How approximate must it be? Instead of counting each head, just determine the area filled (the actual dimensions) and then calculate the density of heads of a sample area. This could be more accurate for pictures that are not bird''s eye view and go out to the horizon. It could also count heads for areas that are blocked but assumed to be filled with people (like shadows, tents, etc).

对于在准备就绪的房间中找不到任何人，您可以使用kinect制成sdk
示例usertracker.net

You can use kinect for no of person found in a room ready made sdk
one of the example usertracker.net
