Question

我正在使用python脚本进行面部验证。它在我的计算机上运行良好，并且在wamp服务器上运行良好。我已允许外部访问我的wamp服务器，因此我也可以通过移动设备访问本地主机。当我在计算机上使用脚本时，它将触发网络摄像头并捕获我的图像并更新数据库（正确）

现在的问题是，每当我通过访问本地主机的IP地址在移动设备上运行相同的脚本时，它就会打开计算机网络摄像头而不是手机摄像头来捕获图像。

我希望脚本从我正在访问的任何设备上捕获图像。

链接获取haarcascade_frontalface_default.xml

此脚本是nazmiasri95在github上发布的代码的修改版，这里是original code

这是我的python代码
