Method and device for determining control error of master-slave collaborative navigation agricultural machinery

The invention provides a control error determination method and device for master-slave collaborative navigation agricultural machinery, and relates to the technical field of control error measurement. The control error determination method for the master-slave collaborative navigation agricultural machinery comprises the following steps: controlling a first agricultural machinery to move according to a reference navigation path, and controlling a second agricultural machinery to move along with the first agricultural machinery; acquiring a target navigation path of the first agricultural machine and a target following path of the second agricultural machine based on a high-precision positioning attitude measurement device; determining a theoretical spacing distance between the first agricultural machine and the second agricultural machine according to the reference navigation path, and determining an actual spacing distance between the first agricultural machine and the second agricultural machine according
