Embodiment 1

[0066] Such as figure 1 As shown, this embodiment provides a distance measuring method, including the following steps:

[0067] Step 101: the main measurement device receives the sound signal for distance measurement;

[0068] Step 102: The main measurement device obtains the spatial transmission distance of the sound signal of the sound signal according to the received sound signal, and the spatial transmission distance of the sound signal of the sound signal is between the main measurement device and the measured distance between the squares.

[0069] The method of the present invention obtains the spatial transmission distance of the sound signal of the sound signal through the sound signal, that is, the distance between the main measuring device and the measured party. Compared with the traditional laser ranging, the method of the present invention is a brand new measuring method. distance measurement method, which can interact with the sound of the measured party to com...

Embodiment 2

[0124] Such as Figure 12 As shown, this embodiment provides a distance measuring device, the distance measuring device is used as the main square measuring device, which includes: a receiving module and a processing module;

[0125] The receiving module is used for receiving the sound signal for ranging;

[0126] The processing module is used to obtain the spatial transmission distance of the sound signal according to the sound signal received by the receiving module, and the spatial transmission distance of the sound signal is the distance between the main measuring device and the measured party.

[0127] The distance measuring device of this embodiment can use sound signals for distance measurement. Compared with the traditional laser distance measuring device, the distance measuring device of the present invention can interact with the sound of the measured party to complete the distance measurement, instead of using the expensive laser generator. The distance measuring d...

Abstract

A method and device for measuring distance. The present method for measuring distance comprises: a measuring side apparatus receives an audio signal used for measuring distance; the measuring side apparatus acquire a spatial transmission distance of the audio signal on the basis of the audio signal received, where the spatial transmission distance of the audio signal is the distance between a measuring side and a measured side. The present method and apparatus for measuring distance are capable of utilizing the audio signal for measuring distance, thus enhancing user experience.

Description

technical field [0001] The invention relates to the field of sound signal processing, in particular to a distance measuring method and equipment. Background technique [0002] Traditional ranging (measuring space distance) equipment is mainly a dedicated laser rangefinder, which has high measurement accuracy and is less affected by the use environment. However, this type of equipment has a single function, is difficult to miniaturize, and consumes a lot of power. It requires a dedicated laser Generator and receiver, the overall solution is difficult to transplant to the terminal equipment, the cost is high, and the application prospect is small. [0003] For a long time, smart terminal devices have been based on the idea of ​​providing users with more convenient functions and more humanized designs, from integrating camera functions to introducing sensors such as heat, optics, temperature, gyroscopes, geomagnetic accelerations, and barometers. The detection and notification...
