Java调用计算机摄像头照相(Rest API的页面操作)
使用开源组件webcam-capture:https://github.com/sarxos/webcam-capture
项目源码GitHub:https://github.com/muphy1112/RuphyRecorder
本例子使用基于Java rest API的页面操作,方便远程拍照
新建Spring Boot项目

启动项目
当前电脑没有摄像头,因此是正常的
以上是关于Java调用计算机摄像头照相(Rest API控制,方便远程拍照)的主要内容,如果未能解决你的问题,请参考以下文章
opencv for android中使用照相机前置摄像头是照片是颠倒的?
android 4.2的版本 照相机界面切换至前摄像头,按返回后再进照相在后摄像头,进去应还在前摄像头
