A multi-source data fusion unexploded bomb detection method based on deep learning

This invention proposes a method for detecting unexploded ordnance using multi-source data fusion based on deep learning. This method primarily addresses the problems of low accuracy and excessive false alarms and missed alarms in existing unexploded ordnance detection technologies. The method comprises: a data processing module processes received magnetic detection data and image data and transmits them to a deep learning model, which then identifies unexploded ordnance; a data storage module records the input and output of the deep learning model; and a display module displays the acquired magnetic field, image, and location of the unexploded ordnance. This invention utilizes both the magnetic detection module and a camera to acquire information, and obtains unexploded ordnance detection results based on multi-source data fusion and deep learning. This effectively avoids the shortcomings of existing detection methods using a single magnetic detection module, resulting in more comprehensive and diverse information, reducing false alarms and missed alarms, further ensuring personal safety, and reducing resource consumption.
