Measuring method and electronic equipment

Abstract

The invention relates to the technical field of measurement and discloses a measuring method and electronic equipment. The measuring method includes: acquiring first distance h between a camera of the electronic equipment at a photographing spot and a reference plane, wherein the reference plane is perpendicular to both the electronic equipment and a material under measurement and is in contact with the material under measurement; photographing at the photographing spot to obtain an image of the material under measurement; determining in the image, start line position and end line position, corresponding to second distance H to be measured, on the material under measurement, as well as an intersection line position of the material under measurement and the reference plane; calculating to obtain first pixel height a between a start line and an end line, and second pixel height b between the center line of a display screen of the electronic equipment and an intersection line; calculating according to the first distance h, the first pixel height a and the second pixel height b to obtain the second distance H. The measuring method and the electronic equipment according to the embodiment allow measurement to be performed in a wide range conveniently and precisely.

Description

technical field [0001] The invention relates to the field of measurement technology, in particular to a measurement method and electronic equipment. Background technique [0002] In life and work, people often need to measure dimensions, such as measuring the length, width, and height of objects. With the rapid integration of mobile terminals into people's lives, many schemes using mobile terminals for auxiliary measurement have been proposed. Among them, in some test schemes, the user is still required to carry the scale with him, and some schemes require the mobile terminal to have an antenna and use the antenna as a scale, and some schemes use the proportional relationship between the image and the actual size at a specific focal length when the camera is imaging. , generating a proportional scale on the display screen of the mobile terminal for measurement. [0003] The inventors of the present invention have found that: in the above measurement method, either auxiliar...

Problems solved by technology

[0003] The inventors of the present invention have found that: in the above measurement method, either auxiliary tools other than the mobile terminal need to be carried, or there are special requirements for the mobile terminal, so it will still cause inconvenience to the measurement, and the proportional scale realized by the display screen is used for measurement. , for larger objects, such as mountains, the measurement accuracy will be affected due to the limited accuracy of the scale
