养老院视频监控分析智能化具备视频监控和报警的双重基本功能，运用简易。养老院视频监控分析针对养老院务需要监控的地区，在软件平台画好区域禁止进入的防区就可以。大部分养老院的老人腿脚不便，摔倒事件经常发生，为避免老年人跌倒，耽误老年人发现救治的最佳时机，养老院视频监控分析智能系统通过监控画面发现老人摔倒，能自动向后台工作人员发送预警提醒，对倒地人员做到及时救助。

Python是一种由Guido van Rossum开发的通用编程语言，它很快就变得非常流行，主要是因为它的简单性和代码可读性。它使程序员能够用更少的代码行表达思想，而不会降低可读性。

与C / C++等语言相比，Python速度较慢。也就是说，Python可以使用C / C++轻松扩展，这使我们可以在C / C++中编写计算密集型代码，并创建可用作Python模块的Python包装器。这给我们带来了两个好处：首先，代码与原始C / C++代码一样快（因为它是在后台工作的实际C++代码），其次，在Python中编写代码比使用C / C++更容易。OpenCV-Python是原始OpenCV C++实现的Python包装器。
