ros kinetic运行摄像头信息发布节点。再运行订阅节点。出现[ERROR] [1540550111.974816949]: Client [/image_subscriber] wants topic /camera/rgb/image_raw/compressed to

have datatype/md5sum [sensor_msgs/Image/060021388200f6f0f447d0fcd9c64743], but our version has


[sensor_msgs/CompressedImage/8f7a12909da2c9d3332d540a0977563f]. Dropping connection.
订阅的话题类型与回调函数的参数不匹配。/camera/rgb/image_raw/compressed 对应sensor_msgs的CompressedImageConstPtr，而不是ImageConstPtr。
