With the development of artificial intelligence technology and the expansion of application scenarios, unmanned equipment is developing in the direction of intelligence. The evaluation of the intelligent level of unmanned equipment can guide and standardize the intelligent development of unmanned equipment, and can fully and reasonably allocate different unmanned equipment management support forces, and then select the appropriate intelligent level of unmanned equipment according to the task scenario. This paper reviews the related meaning of intelligence and the method of evaluating the intelligence of unmanned equipment, reviews the research on intelligent classification of unmanned equipment in recent years, and reviews the research on the construction of intelligent level evaluation index of unmanned equipment. Based on the connotation of intelligence and the development requirements of unmanned equipment, this paper constructs the intelligent level classification and evaluation index system of unmanned equipment from the task completion ability, learning interaction ability and migration generalization ability of unmanned equipment, and carries out thinking and exploration.
