A method for measuring distance and area by a mobile device 50 combined with a light beam projector which projects the light beams in the direction identical to the one of the image retrieved from a photodetector module of the mobile device, to project a first measuring point A and a second measuring point B and produce first distance OA and a second distance OB. The coordinates (X1, Y1, Z1), (X2, Y2, Z2) of the first and second measuring points A, B are calculated with a first azimuth data and a second azimuth data detected by an azimuth sensor of the mobile device. Thus the method can calculate the coordinate distance AB between the first and second measuring points A, B and the area OAB. The method can calculate the coordinate distance between any two points and the measure of the area surrounded thereby, achieving a convenient and augmented effectiveness in the measuring process. |
