A three-dimensional thermal imaging based electromagnetic driven fire extinguishing technology is designed to address the shortcomings of existing fire extinguishing technologies that still require manual operation and have long delays，low accuracy，and are only suitable for open fire environments．This design can determine the optimal fire extinguishing point in the current area through data interpolation and three- dimensional imaging principles，and use electromagnetic cannon driving to vertically hit the optimal fire extinguishing point，achieving dual efficiency in time occupation and fire extinguishing function．It has certain application value for the current intelligent field of fire extinguishing shells and potential fire prevention．
