Abstract
A method for measuring distance and areas by mobile devices combined with light beam projectors that combines a mobile device 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, so as to project a first measuring point and a second measuring point and produce a first distance and a second distance, and then calculate the moving coordinates of the first and second measuring points with a first azimuth data and a second azimuth date detected by an azimuth sensor of the mobile device. Thus the method would be able to calculate the coordinate distance between the first and second measuring points, even the area surrounded by the coordinate distance, the first distance, and the second distance. In other words, 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.
