Abstract

The invention relates to the technical field of terminals, in particular to a distance measuring method, a distance measuring device and a terminal mobile. During ranging, a first visible light ray and a second visible light ray align to a to-be-ranged object, focuses of the first visible light ray and the second visible light ray are coincided, and distance between the to-be-measured object and the mobile terminal is calculated through a first included angle, a second included angle, a third included angle that is between a first display screen and a second display screen, first length of thefirst display screen and second length of the second display screen and through combination with a cosine law, and the first included angle between the first invisible light ray emitted by a first visible light generation unit and the first display screen is equal to the second included angle between the second invisible light ray emitted by a second visible light generation unit and the second display screen. Therefore, simple, convenient and highly accurate distance measuring is achieved.

Description

technical field [0001] The present invention relates to the technical field of terminals, in particular to a ranging method and device thereof, and a mobile terminal. Background technique [0002] With the rapid development of electronic technology, the functions of mobile terminals are becoming more and more powerful, and more and more users choose to use dual-screen mobile terminals to watch videos, browse webpages and other activities. A dual-screen mobile terminal includes a main screen and a secondary screen. Since the positions of the main screen and the secondary screen can be changed relatively, the main screen and the secondary screen can be displayed in different directions. Orientation to watch web pages, browse videos, etc. [0003] In the application process of the mobile terminal, the existing related technology uses the mobile terminal to measure the distance of the object to be measured. However, during the process of implementing the present invention, the...
