The application discloses an autonomous explosive disposal detection system and control method based on an edge full-stack cluster, aiming to solve the computing power bottleneck of the explosive disposal robot in a weak network environment and the reliability problem of grabbing in a complex scene. The system is composed of a four-legged mobile chassis and an execution mechanical arm carrying an airborne edge computing node, and the computing node integrates video processing, Web business hub and comprehensive control layer. The method constructs a full life cycle tactical closed loop: precise searching is realized through spatial tactical calibration, target tracing and macroscopic approach; a dual-mode fault-tolerant architecture based on confidence is innovatively proposed, autonomous grabbing confidence is calculated in real time after tactical anchoring, visual servo grabbing is performed when the confidence is high, the process is automatically suspended and seamlessly switched to a low-delay master-slave synchronous remote control mode when the confidence is low, and finally the safe transfer of explosives is completed. The application greatly improves the operation survival rate and safety of special robots in a broken network and unstructured environment.

The invention discloses an explosive detection processing device based on a laser radar, and relates to the technical field of explosive detection. The device comprises a detection processing system, a laser radar detection mechanism, an image acquisition mechanism, a metal detection mechanism, an X-ray detection mechanism, an explosive detection mechanism and an explosive processing mechanism. The detection processing system comprises a server, an image display unit and an alarm module; the laser radar detection mechanism is used for performing imaging judgment on the shape and the size of an article; the metal detection mechanism is used for detecting whether the article contains metal; the X-ray detection mechanism is used for imaging the interior of the article; the explosive detection mechanism comprises a Raman spectrum acquisition unit and a trace detection unit. The appearance and size of the laser radar are judged, whether most of objects are explosives or not can be eliminated by combining image recognition, metal detection and X-ray detection, and the problem that in the prior art, micro trace detection, Raman spectrum detection and other detection methods cannot be effectively applied to equipment is solved.
