Work machine control system and work machine control method
A work machine control system includes: an acquisition unit configured to acquire a plurality of pieces of current topographical data indicating a current topography of a work site where a work machine performs work; and a combining unit configured to generate combined current topographical data of the work site in accordance with a predetermined rule based on the plurality of pieces of current topographical data acquired in the acquisition unit.
1. A work machine control system comprising:
an acquisition unit implemented in a processor and configured to acquire different kinds of a plurality of current topographical data indicating a current topography of a work site where a work machine performs work by different measuring methods;
a combining unit implemented in the processor and configured to generate combined current topographical data of the work site by adopting a high-priority current topographical data based on priority order of current topographical data set by measurement accuracy per the current topographical data acquired by the acquisition unit when there are a plurality of the current topographical data of corresponding or same position; and
a work unit controller configured to control a work unit based on the combined current topographical data.
2. The work machine control system according to claim 1 , wherein the combining unit generates the combined current topographical data of the work site based on measuring method information or accuracy information of the current topographical data acquired in the acquisition unit.
3. The work machine control system according to claim 1 , wherein the combining unit generates the combined current topographical data of the work site by using priority order or a weighted average.
4. The work machine control system according to claim 1 , wherein the combined current topographical data is generated based on partial current topographical data that is part of the current topographical data.
5. The work machine control system according to claim 1 , wherein the combining unit generates the combined current topographical data of the work site by comparing height data in the current topographical data acquired in the acquisition unit and extracting highest or lowest height data.
6. A work machine control method comprising:
acquiring different kinds of a plurality of current topographical data indicating a current topography of a work site where a work machine performs work by different measuring methods;
generating combined current topographical data of the work site by adopting a high-priority current topographical data based on priority order of current topographical data set by measurement accuracy per the acquired current topographical data when there are a plurality of the current topographical data of corresponding or same position; and
controlling a work unit based on the combined current topographical data.
