资源说明:菜鸟提问基于MATLAB的防盗报警系统的有关问题-voice.m
话不多说,之前有人做出视频防盗系统,详见此贴。
原来的一个版本:视频监控,有东西经过监控区域就报警:
贴子如下:
https://www.ilovematlab.cn/thread-133835-1-1.html
后来又有人加上了声音报警系统。声音过大就会报警。
详见此贴
声音监控,有东西发出声音就进行报警
https://www.ilovematlab.cn/thread-133881-1-1.html
。。
然后就是我们有个大作业,我想到的是将两者结合在一起,在视频监控的同时,如果声音过大就进行报警,然后拍照(要是能把照片发到邮箱就好了)。
以下是我的修改,但是一直报错。希望有人能帮忙修改下实现上面的功能。
