Abstract

The invention discloses a trajectory adjusting method and device. The method comprises the steps of obtaining the amplitude change parameters, wherein the amplitude change parameters are used for indicating the amplitude change of a first trajectory point; determining the target rotation deviation amplitude and the target rotation deviation direction according to the amplitude change parameters, wherein the target rotation deviation amplitude is used for indicating the adjustment amplitude of the trajectory point during adjustment, and the target rotation deviation direction is used for indicating the direction of the trajectory point during adjustment; determining the rotation angle and rotation direction of a second trajectory point according to the target rotation deviation amplitude and the target rotation deviation direction, wherein the second trajectory point is a next trajectory point after the first trajectory point is generated; and adjusting the generation trajectory of thesecond trajectory point according to the rotation angle and rotation direction of the second trajectory point. The trajectory adjusting method and device solve the technical problems that much time iswasted and efficiency is low during trajectory modification.

Description

technical field [0001] The present invention relates to the field of track generation, in particular to a track adjustment method and device. Background technique [0002] Among the data used to describe tasks on many devices in the manufacturing industry, many key data contain "trajectory points" and "trajectories", such as the trajectory describing the motion of the end effector of an industrial robot; the g code describing the machining path of a CNC machine tool; describing Welding machine instructions for welding position and attitude, etc. In order to obtain a good quality of work, the trajectories need to be continuously corrected. In related technologies, when generating trajectories, these trajectories are often generated at one time. If they are modified later, all previous workloads need to be repeated, or Some trajectory batch modification tools cannot modify the parameters of the previous operation, resulting in a waste of time and low work efficiency.
