The invention discloses an overhead line monitoring method and device, and the method comprises the steps: obtaining the field picture information of an overhead line, the operation information of an overhead line monitoring system, and the tree obstacle early warning information according to a preset period, judging whether the data in the operation information is out of limit or is obviously wrong, and if not, carrying out the early warning. If yes, the operation information is abnormal, whether the difference between the distance data of the overhead line and the tree and the tree obstacle confidence coefficient result data in the field picture information and a preset abnormal threshold value is larger than a preset comparison threshold value or not is judged, if not, the tree obstacle early warning information is not abnormal, and if yes, the tree obstacle early warning information is abnormal. If yes, the tree obstacle early warning information is abnormal, and an operation and maintenance scheme corres
