Embodiment 1

[0050] Such as image 3 , Figure 4 Shown is a specific embodiment of the device of the present invention, including a handheld electronic device body 1, which is mainly a shell part of the handheld electronic device. The handheld electronic device also includes a positioning system, a target imaging system and a data processing device.

[0051] Specifically, the positioning system includes a reference rod 2 , which is a right angle component and is rotatably arranged on the body 1 . The reference rod 2 has a first position received in the body 1 (see image 3 State shown) and the second position perpendicular to the body 1 (see Figure 4 status shown).

[0052] The displacement end B of the reference rod 2 is in the same horizontal plane as the base point E1. In this embodiment, the base point E1 is the second camera.

[0053] The above-mentioned positioning system is used to set the positional relationship between the handheld electronic device and the target object, s...

Embodiment 2

[0060] Such as Image 6 Shown is another specific embodiment of the device of the present invention. The structure of this embodiment is basically the same as that of the above-mentioned embodiments, except that the data processing device is a data processing system instead of a reference scale.

[0061] The data processing system is a built-in computing program associated with the control circuit of the liquid crystal display. When the virtual image E of the target object A is displayed on the LCD screen, the data processing system converts the actual distance E2E between the virtual image E and the first camera E2 according to the pixel data corresponding to the display position, and then combines the body 1 The fixed parameter values ​​E2E1 and E1B of the above calculation formula are used to obtain the target data E1A, and the data E1A is directly displayed on the LCD screen in digital form, such as Image 6 The words "Target Distance: 518m" displayed in the

Embodiment 3

[0064] The ranging method of the present invention is the application of the above-mentioned device, combining image 3 , Figure 4 Shown, this method comprises the following steps in a specific embodiment:

[0065] Step 1: Use the positioning system on the handheld electronic device to form a connection line between the base point E1, the reference point B, and the target object A, and at the same time make the body 1 of the handheld electronic device perpendicular to the connection line E1B;

[0066] Specifically, first make the reference rod 2 by image 3 The first position shown becomes Figure 4 The second position shown, and then connect the second camera E1 used as the base point, the reference point B and the target A in a straight line through the line of sight, that is, the reference B in the viewfinder interface of the second camera E1 completely blocks the target A .

[0067] Step 2, the virtual image E of the object A on the imaging component 4 is captured by ...

Abstract

The invention discloses a handheld electronic device with a distance measurement function for measuring a distance between the handheld electronic device and a target object. The handheld electronic device with the distance measurement function comprises a main body, and further comprises a positioning system for setting a position system between the main body and the target object; a target object imaging system for obtaining a virtual image of the target object on the main body; and a data processor for converting and obtaining the distance between the handheld electronic device and the target object according to different display positions of the virtual image in the main body. The invention also discloses a distance measurement method of the handheld electronic device. The device and the method, provided by the invention, get rid of interference of manual factors, and have the advantages of accurate distance measurement result, high repeatability, and simple and convenient application and the like.

Description

technical field [0001] The present invention relates to the technical field of electronic communication, in particular to a handheld electronic device with distance measuring function, such as a mobile phone, and a distance measuring method thereof. Background technique [0002] People often need to measure the distance of distant objects in their work and life. In addition to using physical tools such as tape measures to measure, other principles and methods can also be used to measure distance. [0003] For example, using sound waves, the Chinese invention patent with the publication number CN1979088 discloses a mobile phone device and a distance measuring method using sound waves for distance measurement. This device requires two mobile phones to be used together, which limits its application. [0004] Such as utilizing ultrasonic waves, the Chinese utility model whose publication number is CN201153276 discloses a kind of mobile phone with ultrasonic ranging function, an...
