Unexploded ordnance (UXO, sometimes abbreviated as UO), unexploded bombs (UXBs), or explosive remnants of war (ERW) are explosive weapons (bombs, shells, grenades, land mines, naval mines, cluster munition, etc.) that did not explode when they were employed and still pose a risk of detonation, sometimes many decades after they were used or discarded. UXO does not always originate from wars; areas such as military training grounds can also hold significant numbers, even after the area has been abandoned. UXO from World War I continue to be a hazard, with poisonous gas filled munitions still a problem. When unwanted munitions are found, they are sometimes destroyed in controlled explosions, but accidental detonation of even very old explosives also occurs, sometimes with fatal results.
An intelligent detection method and device for unexploded ordnance, an electronic device and a medium
The application provides a kind of intelligent detection method, device, electronic equipment and medium for unexploded bomb, effectively solve the problem of low detection accuracy caused by iron ore and other geological disturbances in the existing unexploded bomb detection method.The method comprises: obtaining original magnetic data, determining magnetic data based on the original magnetic data, controlling the detection model to preprocess the magnetic data to obtain target magnetic data, extracting features to obtain time sequence features and frequency spectrum features respectively;Fusion of the time sequence feature and the frequency spectrum feature obtains the unexploded bomb feature, and constructs the pyramid feature map of the unexploded bomb feature to detect based on the pyramid feature map to obtain multiple candidate detection results;According to the pre-set screening method, the target detection result is screened out from the multiple candidate detection results, to detect the unexploded bomb in the to-be-detected area based on the target position information in the target detection result.

Object detection precision enhancement methods, tools and systems
The present invention is directed to improved precision in object detection, reducing the false positive rates. In particular, the present invention is directed to improved methods, tools and systems of detecting and identifying objects, such as explosives (e.g., landmines and unexploded ordnance) using an unmanned aerial vehicles. The present invention offers solutions to the problem of the high rate of false positives that take time and resources away from real objects, such as these landmines.

A scalable magnetic gradient unmanned aerial vehicle (UAV) unexploded ordnance detection mechanism
This invention provides an expandable magnetic gradient unmanned aerial vehicle (UAV) unexploded ordnance (UAV) detection mechanism, belonging to the technical field of detection mechanisms. This expandable magnetic gradient UAV UAV unexploded ordnance detection mechanism includes a multi-rotor UAV platform, UAV landing gear, a single-axis non-magnetic mounting rod, cesium optically pumped magnetometer probes, and a magnetic gradient collector. The single-axis non-magnetic mounting rod is horizontally fixed below the UAV platform, with cesium optically pumped magnetometer probes installed at both ends, forming a single-axis dual-probe magnetic gradient detection unit. An extension shaft connecting rod is also provided, which is vertically connected to the single-axis non-magnetic mounting rod via a quick-connect interface. Cesium optically pumped magnetometer probes are installed at both ends of the extension shaft connecting rod, together with the single-axis non-magnetic mounting rod, forming a dual-axis four-probe magnetic gradient detection unit. The magnetic gradient collector is located inside the UAV fuselage and is electrically connected to each cesium optically pumped magnetometer probe, solving the problems of insufficient detection accuracy and low deployment efficiency of traditional UAV unexploded ordnance detection mechanisms in complex environments.
