The invention discloses an intelligent pipeline detecting and monitoring device, which comprises an information acquisition terminal used for acquiring image information and distance information and adisplay control terminal used for displaying the image information. The intelligent pipeline detecting and monitoring device realizes monitoring for the internal environment of a pipeline and measurement for the distance of a target object through the information acquisition terminal and the display control terminal, and enables the measurement data to be superimposed in a video image, thereby enabling the staff to know conditions inside the pipeline more efficiently and more conveniently so as to be more conducive to distance measurement for the target object.
