Abstract

A method and apparatus for determining a boundary of a work area are provided in an embodiment of that present application. The method include: acquiring a plurality of track points of a movable object when performing a work on the work area; generating an initial trajectory range according to the plurality of trajectory points; dividing the initial trajectory range into a plurality of grids according to a preset interval; determining a boundary of the work area according to a positional relationship between the plurality of track points and the plurality of grids. The embodiment directly determines the boundary through the collected information of the trajectory points, effectively improves the accuracy of the boundary, and solves the problem that the boundary error of extracting the workarea by the convex hull algorithm in the prior art is large.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and a device for determining the boundary of an operation area. Background technique [0002] Usually, by extracting the running trajectories of various things, the corresponding boundary information can be obtained. For example, the boundary information of the farmland can be extracted according to the operation trajectory of the agricultural machinery and equipment in the farmland; the road boundary can be extracted according to the driving trajectory of the vehicle, and so on. [0003] However, for some trajectories formed by discontinuous trajectory points, the boundary information of the trajectories cannot be extracted directly. Such as figure 1 As shown, it is a schematic diagram of a track point, which may be the actual operation track when the agricultural machinery equipment is working. For example, when the harvester is harvesting crops, the act...
