Abstract

See full text

A trajectory generation method includes: obtaining distance information which a ranging apparatus has traveled; obtaining, from a sensor system, first angle information and second angle information corresponding to the ranging apparatus when the ranging apparatus is traveling in a space; determining a plurality of target sample points for a trajectory diagram of the space, and generating the trajectory diagram by connecting the plurality of target sampling points. Determining the target sample points includes: using a candidate sample point as one of the plurality of target sample points; in response to a trajectory adjustment condition not being satisfied, determining coordinates of the candidate sample point based on the distance information and the first angle information; and in response to the trajectory adjustment condition being satisfied, adjusting the candidate sample point based on the distance information, the first angle information, and the second angle information.
