Kind Code:
A1
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 1 that assists work of an operator by using a machine guidance function, the work assistance system 1 comprises: a sensor unit 11 that is held by a moving part 5 of a construction machine 2 and acquires attitude information by using a sensor; and a portable information terminal device 13 that acquires, by means of data communication with the sensor unit 11, the attitude information acquired by the sensor unit 11, 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 SP2 for acquiring an imaging result from the moving part 5 having the sensor unit 11; an error calculation step SP5 for subjecting the imaging result to image processing to calculate a mounting error of the sensor unit 11 with respect to a reference mounting position; and a correction step SP6 for using the mounting error to correct the attitude information.
