Abstract

A method for measuring a real size of an object using a camera of a mobile terminal, includes the steps (1) recognizing an object image taken using a camera of a mobile terminal; (2) measuring a size of an object image recognized in step (1); (3) measuring a distance between the object and the camera; and (4) computing a real size of the object using the characteristic of the camera, the size of the object image measured in step (2), and the distance between the object measured in step (3) and the camera. In a method of measuring a real size of an object by using a camera of a mobile terminal, it is possible to measure an accurate real size of an object by using a simpler, faster method like a scale method. The size of the object is measured by using the camera of the mobile terminal and the distance between the camera and the object and the real size of the object is calculated by utilizing the characteristics of the camera like camera of focal lengths and measured values.

Description

technical field [0001] The present invention relates to a method for measuring the actual size of an object, and more particularly, to a method for measuring the actual size of an object through a camera of a mobile terminal. Background technique [0002] People have experienced many things in life, and sometimes they need to measure something, such as the length, height and area of ​​buildings or objects. For example, people want to know the real size of something, such as furniture, a desk or similar household items, or want to know the height of a building erected in the street. [0003] In the case of furniture, desks or the like, the true dimensions can easily be found by asking the staff or the manufacturer. If one needs to know the size of an exhibit window, or there is no staff to ask, or the exhibit window is closed at the sales office, it is impossible to know the true size of the same thing. If living items, not furniture, real size information is not provided. ...
