1. A work estimation apparatus comprising processing circuitry configured to:
acquire video data on a predetermined area;
calculate a work value related to work performed by a worker included in the video data, based on the video data, wherein the work value includes a load value that represents a physical load which the work imposes on the worker;
calculate a posture feature amount of the worker by applying a skeleton estimation model to the video data;
estimate a working posture of the worker, based on the posture feature amount;
calculate the load value, based on the working posture;
estimate a work target of the work performed by the worker from among one or more work target candidates, based on a sketch of the predetermined area in which the working posture and one or more work target candidates are associated with each other; and
display the work value.
