Abstract

The invention discloses a method, an apparatus and an electronic instrument for distance measurement. The method comprises the following steps: acquiring a first image of a reference object at a detection position; acquiring dimension information of the reference object in the first image; ad acquiring the distance between the detection position and the reference object according to the standard dimension information of the reference object and the dimension information of the reference object in the first image. Compared with the prior art, the method, the apparatus and the electronic instrument for distance measurement provided by embodiments in the invention have the following advantages: measuring places are not restricted during measurement of horizontal distance or vertical height, and the measuring process is convenient and simple.

Description

technical field [0001] The present application relates to the field of measurement technology, in particular to a distance measurement method, device and electronic equipment. Background technique [0002] There are many ways to measure the height of an object, that is, the distance from the bottom to the top of the object in the direction perpendicular to the ground, or to measure the distance from one object to another object in a plane. For example, there are many ways to measure height, and the simplest is to use a ruler to measure directly. This measurement method usually requires the assistance of other personnel to complete. The operation is cumbersome, and the obtained height data is not accurate and is only an approximate value. [0003] Taking height measurement as an example, the usual method is to use measuring instruments to measure height, and these measuring instruments may be mechanical measuring devices or electronic measuring devices. Among them, the mecha...
