Abstract
This work region estimation device, which estimates a region in which a worker performs work, is provided with: a first operation acquisition unit that acquires worker operation information; an orientation acquisition unit that acquires worker orientation information; and a work region calculation unit that, on the basis of the operation information, the orientation information, and a worker body model, calculates a region in which a worker operation is forecast.
Claims17
A control device comprising:
- a work region estimation device which estimates a region in which a worker performs work;
- and
- a control unit,
- wherein the work region estimation device comprises:
- a processor;
- a memory, coupled to the processor,
- wherein the processor is configured to function as:
- a first operation acquisition unit configured to acquire operation information of the worker;
- an orientation acquisition unit configured to acquire orientation information of the worker;
- and
- a work region calculation unit configured to calculate a region in which a worker operation is forecast on the basis of the operation information, the orientation information and a human body model of the worker,
- wherein the control unit is configured to control a control target based on the region in which the worker operation is forecast,
- wherein the orientation information includes the orientation information of the body of the worker and the orientation information of the head of the worker,
- wherein the work region calculation unit is further configured to perform a weighted evaluation for operability in the region in which the worker operation is forecast on the basis of the orientation information of the body and the orientation information of the head,
- wherein the control unit is further configured to operate the control target outside a region in which the operability is equal to or greater than a predetermined value.
