Abstract: A method for measuring coordinate position include detecting the distance of a target relative to a portable electronic device to generate a measurement signal corresponding to the distance, sensing a relative position of the target to generate a azimuth angle corresponding to the relative position, detecting the movement of the portable electronic device to generate an inertial signal corresponding to the movement, obtaining positioning information of the portable electronic device, converting the measurement signal into distance data, converting the inertial signal into a tilt angle, calculating coordinate difference information with the tilt angle, the distance data and the azimuth angle, and calculating coordinate position of the target with the positioning information and the coordinate difference information.
