Abstract

See full text

A method for laser distance measuring includes: emitting an incident ray α having an incident angle δ to a reflective surface of a laser reflecting mirror (31), the incident ray α being reflected by the laser reflecting mirror (31) to generate a first reflected ray β, and the first reflected ray β irradiating an object to be measured (1000); capturing a second reflected ray θ and generating a laser image on a laser imaging plane (3221), the second reflected ray θ being generated by the reflective surface of the laser reflecting mirror (31) reflecting a return ray γ generated after the first reflected ray β irradiates a surface of the object to be measured; and determining, based on the laser image, a measurement distance A according to a geometrical trigonometry.
