Abstract: A method can measure the size of an object using a terminal having two cameras. The method includes obtaining, by a terminal using a first camera, a first image that includes a to-be-measured object, and obtaining, using a second camera, a second image that includes the to-be-measured object, where the first camera and the second camera are disposed in a same plane. The method also includes comparing locations of the to-be-measured object in the first image and in the second image, so as to obtain a total location offset of the to-be-measured object. Additionally, the method includes receiving a measurement point selection instruction entered by a user based on the first image, and calculating a distance between selected measurement points according to the total location offset, a distance between a center of the first camera and a center of the second camera, and a focal length of the first camera.
