Embodiment 1

[0072] This embodiment provides a method for measuring a distance, which is applied to an electronic device, and the electronic device includes an image acquisition unit or the electronic device is connected to an image acquisition unit. Such as figure 1 As shown, the method for measuring distance includes:

[0073] Step S101: controlling the image acquisition unit to acquire an image of a target object at a ranging position to obtain a first picture containing the target object;

[0074] Step S102: determining a first display area of ​​the target object in the first picture;

[0075] Step S103: controlling the image acquisition unit to acquire an image of the target object at a reference position to obtain a second picture containing the target object, the ranging position being different from the reference position;

[0076] Step S104: determining a second display area of ​​the target object in the second picture;

[0077] Step S105: Acquiring a first actual distance betw...

Embodiment 2

[0129] Based on the same inventive idea, such as Image 6 As shown, this embodiment provides an electronic device, the electronic device includes an image acquisition unit or the electronic device is connected to an image acquisition unit, and the electronic device further includes:

[0130] The first acquisition unit 201 is configured to control the image acquisition unit to acquire an image of a target object at the ranging position, and obtain a first picture containing the target object;

[0131] A first determining unit 202, configured to determine a first display area of ​​the target object in the first picture;

[0132] The second acquisition unit 203 is configured to control the image acquisition unit to acquire an image of the target object at a reference position to obtain a second picture containing the target object, and the ranging position is different from the reference position;

[0133]A second determining unit 204, configured to determine a second display ar...

Abstract

The present disclosure provides a method for measuring a distance. The method may comprise: controlling an image collection unit to collect an image of an object at a measuring position to obtain a first picture including the object; determining a first displaying area of the object in the first picture; controlling the image collection unit to collect an image of the object at a reference position to obtain a second picture including the object, the measuring position being different from the reference position; determining a second displaying area of the object in the second picture; obtaining a first actual distance from the measuring position to the reference position; and determining a second actual distance from the object to the measuring position based on the first displaying area, the second displaying area and the first actual distance. Meanwhile, the present disclosure further discloses an electronic device.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a method for measuring distance and electronic equipment. Background technique [0002] With the development of science and technology, smart phones have been widely popularized, bringing many conveniences to people's lives. [0003] In the prior art, when a smartphone is used to take pictures of a target object, stereo vision can be used to obtain two pictures of the target object at different camera angles through two cameras, and generate corresponding depth images to determine the target The actual distance of the object to the smartphone. [0004] But the inventor finds that there are at least the following technical problems in the above-mentioned technology: [0005] In the method of measuring distance in the prior art, if the distance measurement is to be performed on a long-distance target object, the distance between the two cameras needs to be increased (taking t...
