安装Ubuntu20.04安装gcc和gIDmvs只提供了C代码所以需要自己make编译自己去搜下怎么安装。官网下载IDMVS软件进入海康机器人页面进入下载选项选择客户端下载第二页选择里面的IDMVS(linux)解压安装我是用deb文件安装的选择X86_64版本。安装完成后在菜单栏里面有IDMVS图标可以直接打开或者进入/opt/IDMVS/bin/,运行./IDMVS.sh两种方法都能打开客户端。连接相机如果没有找到相机你可以在windows上先连下相机试试然后设定固定IP连接相机连上之后进入/opt/IDMVS/有个demo的文件夹具体在哪里忘记了可以找一下IDMVS只提供了两个demo进入/GrabImage/目录下应该只有两个文件一个GrabImage.c一个makefile。 然后把上级目录下的/sdk/里面的.so文件放到/GrabImage/目录下。然后sudo make(如果你之前装好了g和gcc应该可以make成功)执行生成后的文件。./GrabImage就OK了选择你想要连接的相机。就能看到获取到的结果了。
