Document Type and Number:
WIPO Patent Application WO/2023/136326
Kind Code:
A1
Abstract:
According to the present invention: the orientation of a work machine at a work site is calculated on the basis of orientation information about the work machine output from an orientation measurement device; a loading area is set where a conveyance device stops and loading work from the work machine to the conveyance machine is performed; whether the work machine can detect the conveyance device that has stopped in the loading area is determined by an external measurement device on the basis of the orientation of the work machine; and when it has been determined that the work machine can detect the conveyance device, the conveyance machine is detected on the basis of measurement information output from the external measurement device. Accordingly, it is possible to more accurately detect a vessel position of a stopped conveyance device, and appropriately assist loading work by a work machine.
