This invention discloses an edge-fitting detection method and system based on the pose calculation of a dual-body articulated road roller, relating to the field of automatic control technology for engineering machinery. It aims to solve the trajectory inconsistency problem in edge-fitting operations of articulated vehicles by establishing a vector kinematic chain model. The invention includes constructing a vector geometric model of the articulated road roller; obtaining the global coordinates of the articulation point based on the position information of the GNSS positioning antenna and the independent heading angle of the front frame, and determining the pose of the rear frame; determining the global coordinates of the tangent points of the front and rear steel wheels based on the independent heading angles of the front and rear frames, generating a dynamic operating envelope for the current moment; identifying the point in the dynamic operating envelope closest to the preset operating boundary as a key point, and using the distance between this key point and the preset operating boundary as the effective edge-fitting deviation. This invention can accurately describe the independent motion state of the front and rear frames and can calculate the position of the steel wheel edges in real time, improving the safety and accuracy of edge-fitting operations.
