DISTANCE MEASUREMENT METHOD AND DEVICE, CAMERA, AND MOBILE TERMINAL

WIPO Patent Application WO/2018/082184

A1

A distance measurement method and device, a camera, and a mobile terminal. The camera comprises: a lens (10), a first laser source (11, S1), and a second laser source (12, S2). The second laser source (12, S2) and the first laser source (11, S1) are spaced at a first distance (d1). The first laser source (11, S1) and/or the second laser source (12, S2) are connected to an angular deflection device to deflect a laser beam of the first laser source (11, S1) and/or the second laser source (12, S2) according to a preset angle (θ). The first laser source (11, S1) and the second laser source (12, S2) are located on the same straight line perpendicular to an optical axis of the lens (10). The distance (D) between a measured object and the camera can be measured by means of the lens (10) and at least two laser sources (11, 12, S1, S2). Compared with the prior art, the distance measurement method is simple and easy to operate, and can improve the calculation efficiency, reduce costs, and achieve high precision measurement.
