Cloud-edge collaborative intelligent early warning method and system for hidden danger of long-distance pipeline

The invention provides a cloud-side collaborative intelligent early warning method and system for hidden dangers of a long-distance pipeline. In the method applied to the cloud-edge collaborative long-distance pipeline hidden danger intelligent early warning system, edge end equipment acquires a detection area image of the surrounding environment of an oil and gas long-distance pipeline, wherein the detection area image is acquired by image acquisition equipment; carrying out defogging processing on the detection area image frame by frame to obtain a defogged image; preliminarily detecting whether a hidden danger target exists in the defogged image or not; if the result of the preliminary detection is that the hidden danger target exists, sending the result of the preliminary detection and a continuous preset number of frames of defogged images containing the hidden danger target to a cloud server; and the cloud server performs fine detection on whether a hidden danger target exists in the received defogged i
