A work position correction method for operating a multi-joint type work robot by designating a target position, the method comprising: setting multiple work points in a movable area of the work robot; setting a correction parameter in which a spatial coordinate value and a correction value are associated with respect to the set multiple work points; and reflecting the set correction parameter on the target position. the work position correction method, further comprising: performing a matrix measurement by setting the multiple work points, sequentially designating each spatial coordinate value of the set multiple work points to the target position, moving the work robot, and measuring an actual position of the work robot at each work point so as to derive a difference between the spatial coordinate value of each work point and the measured actual position; and performing a matrix correction by deriving a correction value for each work point based on the derived difference, associating the spatial coordinate value and the derived correction value for each work point, and setting the correction parameter so as to reflect the set correction parameter on the target position, and before the matrix measurement, performing a geometry adjustment of adjusting a conversion parameter used for a coordinate transformation of the target position. setting multiple work points in a movable area of the work robot; setting a correction parameter in which a spatial coordinate value and a correction value are associated with respect to the set multiple work points; and reflecting the set correction parameter on the target position. the work position correction method, further comprising: performing a matrix measurement by setting the multiple work points, sequentially designating each spatial coordinate value of the set multiple work points to the target position, moving the work robot, and measuring an actual position of the work robot at each work point so as to derive a difference between the spatial coordinate value of each work point and the measured actual position; and performing a matrix correction by deriving a correction value for each work point based on the derived difference, associating the spatial coordinate value and the derived correction value for each work point, and setting the correction parameter so as to reflect the set correction parameter on the target position, and before the matrix measurement, performing a geometry adjustment of adjusting a conversion parameter used for a coordinate transformation of the target position. performing a matrix measurement by setting the multiple work points, sequentially designating each spatial coordinate value of the set multiple work points to the target position, moving the work robot, and measuring an actual position of the work robot at each work point so as to derive a difference between the spatial coordinate value of each work point and the measured actual position; and performing a matrix correction by deriving a correction value for each work point based on the derived difference, associating the spatial coordinate value and the derived correction value for each work point, and setting the correction parameter so as to reflect the set correction parameter on the target position, and before the matrix measurement, performing a geometry adjustment of adjusting a conversion parameter used for a coordinate transformation of the target position.
