Embodiment 1

[0026] figure 1 It is a schematic flowchart of the height measurement method provided in the first embodiment of the present invention. The method is suitable for measuring the vertical height of an object within the visible distance, and the method can be executed by a height measuring device provided in the mobile terminal. The height measuring device can be implemented by software and / or hardware. Such as figure 1 As shown, the method includes:

[0027] Step 110: After focusing, obtain the imaging height of the object to be measured on the photosensitive surface of the camera.

[0028] Exemplarily, when measuring the height of the object to be measured, click the height measurement icon on the mobile terminal, and the mobile terminal will automatically turn on the camera; use the camera of the mobile terminal to focus the object to be measured, and after focusing, the height measuring device acquires the photosensitive surface of the camera For the image formed by the object t...

Embodiment 2

[0045] Figure 5 It is a structural block diagram of the height measuring device provided in the second embodiment of the present invention. Such as Figure 5 As shown, the device includes: an imaging height acquisition module 20, an image distance calculation module 21, an object distance calculation module 22, and a height calculation module 23.

[0046] Wherein, the imaging height obtaining module 20 is used to obtain the imaging height of the object to be measured on the photosensitive surface of the camera after focusing;

[0047] The image distance calculation module 21 is used to calculate the image distance according to the displacement of the motor in the camera;

[0048] The object distance calculation module 22 is used to calculate the object distance according to the image distance and the focal length of the lens;

[0049] The height calculation module 23 is used to calculate the height of the object to be measured according to the imaging height, image distance and objec...

Abstract

The invention discloses a height measuring method and apparatus, and a mobile terminal, wherein the method comprises acquiring the imaging height of an object to be detected on a light-sensitive surface of a camera after focusing; calculating the image distance according to the displacement of a motor in the camera; calculating the object distance according to the image distance and the focal length of a lens; and calculating the height of the object to be detected according to the imaging height, the image distance and the object distance. The height measuring method and apparatus can solve the problem that operation is complicated when a mobile terminal is used to measure the height of the object so that the user can easily and quickly measure the height of the object.

Description

Technical field [0001] The invention belongs to the technical field of mobile terminals, and relates to a height measurement method, device and mobile terminal. Background technique [0002] In daily life, people sometimes need to measure the height of objects at a certain distance. In the measurement process, they usually need to use measuring instruments that are inconvenient to carry and the operation is complicated. [0003] With the development of electronic technology, some mobile terminals with camera functions, such as smart phones and tablet computers, have gradually been popularized. Currently, the use of mobile terminals to measure the height of distant objects has become a reality. For example, take two photos of the object to be measured at different distances from the same straight line of the object to be measured, and calculate the object to be measured based on the vertical viewing angle of the camera during the two shots and the height of the object to be measure...
