Abstract
The present invention enables proper assistance of an operation by an operator even when a sensor is not disposed in the correct position. In a method for controlling a work assistance system that assists work of an operator by using a machine guidance function, the work assistance system comprises: a sensor unit that is held by a moving part of a construction machine and acquires attitude information by using a sensor; and a portable information terminal device that acquires, by means of data communication with the sensor unit, the attitude information acquired by the sensor unit, and that, on the basis of the attitude information, reports information for assisting an operation by the operator. The method for controlling the work assistance system comprises: an imaging result acquisition step for acquiring an imaging result from the moving part having the sensor unit; an error calculation step for subjecting the imaging result to image processing to calculate a mounting error of the sensor unit with respect to a reference mounting position; and a correction step for using the mounting error to correct the attitude information.
