Abstract: Based on the theory of quaternion, A camera survey model was constructed to measure the relative position and attitude of agricultural muti-agents, the order of the matrix was reduced, the amount of calculation was effectively reduced, the calculation efficiency and precision of the relative position and attitude are improved, and the requirements of the precision and real-time of the agricultural machinery autonomous relative navigation can be met, and conducted the simulation experiment. The simulation results showed that this method can provide relatively accurate relative position & attitude information.

Key words: agricultural muti-agents, quaternion, relative position and attitude
