A measurement method, comprising: obtaining, by a terminal by using a first camera, a first image that comprises a to-be-measured object, and obtaining, by using a second camera, a second image that comprises the to-be-measured object, wherein the first camera and the second camera are disposed in a same plane; 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, wherein the total location offset is used to represent an offset of the location of the to-be-measured object in the first image relative to the location of the to-be-measured object in the second image; and 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; wherein after the 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, the method further comprises: compressing imaging data of the first image and the total location offset, and storing the imaging data of the first image and the total location offset that are compressed as an image file; and before the receiving a measurement point selection instruction entered by a user based on the first image, the method further comprises: parsing the image file, so as to obtain the imaging data of the first image and the total location offset; and decoding the imaging data, so as to display the first image on a screen of the terminal. obtaining, by a terminal by using a first camera, a first image that comprises a to-be-measured object, and obtaining, by using a second camera, a second image that comprises the to-be-measured object, wherein the first camera and the second camera are disposed in a same plane; 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, wherein the total location offset is used to represent an offset of the location of the to-be-measured object in the first image relative to the location of the to-be-measured object in the second image; and 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; wherein after the 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, the method further comprises: compressing imaging data of the first image and the total location offset, and storing the imaging data of the first image and the total location offset that are compressed as an image file; and before the receiving a measurement point selection instruction entered by a user based on the first image, the method further comprises: parsing the image file, so as to obtain the imaging data of the first image and the total location offset; and decoding the imaging data, so as to display the first image on a screen of the terminal. compressing imaging data of the first image and the total location offset, and storing the imaging data of the first image and the total location offset that are compressed as an image file; and before the receiving a measurement point selection instruction entered by a user based on the first image, the method further comprises: parsing the image file, so as to obtain the imaging data of the first image and the total location offset; and decoding the imaging data, so as to display the first image on a screen of the terminal. parsing the image file, so as to obtain the imaging data of the first image and the total location offset; and decoding the imaging data, so as to display the first image on a screen of the terminal.
