The invention relates to the field of automatic driving, in particular to an automatic driving track prediction system and a track coordinate conversion method. Obtaining a to-be-predicted searching position and storage input positioning of surrounding obstacles in a large database coordinate system; the motion trail prediction system provided by the invention carries out layer superposition on data packets of a map area where a to-be-predicted searching position is located and surrounding obstacles to obtain a three-dimensional diagram containing the data packets; and inputting the obtained storage input and three-dimensional diagram of the to-be-predicted location and the surrounding obstacles in a large database coordinate system into a trajectory prediction system for prediction to obtain a trajectory layer of a future trajectory of the to-be-predicted location, and finally, through the trajectory coordinate conversion method provided by the invention, the trajectory of the to-be-predicted location is obtained. And obtaining a coordinate set of the x coordinate and the y coordinate of the future trajectory to be predicted for locating in the coordinate system of the universal transverse Mercator grid system.
