A method for measuring three-dimensional direction and coordinate of a spot using three distance measuring sensors is provided to attach a cone patch to the spot for to measuring in order to read the direction and coordinate of the location. A method for measuring three-dimensional direction and coordinate of a spot using three distance measuring sensors comprises next steps. A cone patch is adhered to the specific location at the lower part center of the specific location. Three distance measuring sensors measuring the distance to the patch(1,2,3) are installed on the same circumference to be regular triangle while separated with the patch but facing the patch. A direction and coordinate the reference spot of the specific location is calculated based on the measured distances.
