Abstract
The present disclosure relates to the technical field of computers, and provides a nearest neighbor trajectory query method and apparatus, an electronic device, and a readable storage medium. The nearest neighbor trajectory query method comprises: acquiring a first trajectory to be queried, and determining spatial position information of the first trajectory; generating a trajectory signature according to a positional relationship between the spatial position information of the first trajectory and a region to be queried; determining a spatial position index code of the first trajectory by means of XZ-Ordering; and constructing a spatial range index of the first trajectory according to the trajectory signature and the spatial position index code.
