ROS 报错：error: invalid use of non-static member function

代码：

rs_camera_info_subscriber_ = nh.subscribe("camera/color/camera_info", 1, &ContinuousDetector::rsCameraInfoCallback);

error: invalid use of non-static member function
ubscriber_ = nh.subscribe(“camera/color/camera_info”, 1, ContinuousDetector::rsCameraInfoCallback);

原因：
subscriber 使用的回调函数（这里是ContinuousDetector::rsCameraInfoCallback）是类的成员函数，需要声明。

解决办法：
在回调函数名后面加一个参数：this
此处应该是：

rs_camera_info_subscriber_ = nh.subscribe("camera/color/camera_info", 1, &ContinuousDetector::rsCameraInfoCallback, this);
