Abstract: Now a day’s multiple images special photographing poses methods are used to measure the distance from the real world, these methods are able to measure the height with a special view configuration but not enough to measure the depth, ground distance from the real time. We propose a novel image-based method that can measure various types of distance from a single image captured by a smart mobile device. The embedded accelerometer is used to determine the view orientation of the device. In this system pixels can be back-projected to the ground; there are many efficient calibration methods using two known distances. Then the distance in a pixel is transformed to a real distance in centimeter with a linear model parameterized by the magnification ratio. Various types of distance specified in the image can be computed accordingly.
