Embodiment 1

[0055] figure 1 It is a flow chart of a method for measuring human body height provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where a smart terminal equipped with a camera and a distance measuring sensor is used to measure human body height. This method can be implemented by a human body height measuring device Execution, the device can be realized by hardware and / or software, and the method for measuring human body height specifically includes the following steps:

[0056] Step 110, acquiring an image through a camera.

[0057] Wherein, the camera includes a lens and an image sensor. In this embodiment, the lens of the camera is a fixed-focus camera, and the image sensor may be a CCD (Charge-coupled Device, charge-coupled device) or a CMOS (Complementary Metal Oxide Semiconductor, complementary metal oxide semiconductor).

[0058] Step 120, when the user image in the image is a whole-body image, acquire the distance between ...

Embodiment 2

[0066] figure 2 It is a flow chart of a human body height measurement method provided by Embodiment 2 of the present invention. The technical solution of this embodiment is further refined on the basis of the above embodiments. After step 110, it also includes:

[0067] Step 210: Perform edge detection on the image to obtain an edge detection map.

[0068] Wherein, the edge detection is performed on the image acquired by the camera, for example, the CANNY method, the SOBEL method, the ROBERTS method or the PREWITT method may be used to perform the edge detection on the image. The edge detection map is the image outlined by the edge lines of the graph obtained after edge detection.

[0069] Step 220 , according to the edge detection map, obtain the head contour and foot contour of the human body.

[0070] Wherein, in the edge detection image, the contour lines of the human body are screened out, and it is determined whether the contour lines of the human body include the con...

Embodiment 3

[0078] image 3 It is a flow chart of a human body height measurement method provided by Embodiment 3 of the present invention. The technical solution of this embodiment is further refined on the basis of the above embodiments, and before step 130, it also includes:

[0079] Step 310, according to the head profile, determine the first pixel point in the image sensor corresponding to the highest point of the user's head in the image.

[0080] Step 320, according to the outline of the foot, determine the second pixel point in the image sensor corresponding to the lowest point of the user's foot in the image.

[0081] Among them, the image sensor in the camera is made up of a certain number of pixels arranged, and the image obtained by the camera is a bitmap, that is, an image composed of a corresponding number of pixels. After obtaining the user's head profile, you can The pixel at the highest point of the user's head in the image is determined, and then the corresponding pixel...

Abstract

The embodiment of the invention discloses a human body height measuring method, a human body height measuring device and an intelligent mirror. The human body height measuring method comprises the steps of obtaining an image through a camera; when a user image in the image is a whole body image, obtaining the distance from a user to a lens of the camera through a distance measuring sensor; calculating the user height according to the distance from the user to the lens of the camera, the distance from the lens of the camera to an image sensor, and the imaging height of the user on the image sensor of the camera; showing the user height to the user in the preset showing mode. The technical scheme provided by the embodiment has the advantages that the user image is obtained through the camera; the distance from the user to the camera is measured; the user height is calculated and showed to the user; the height measuring convenience is improved.

Description

technical field [0001] Embodiments of the present invention relate to measurement technology, and in particular to a method, device and smart mirror for measuring human body height. Background technique [0002] Nowadays, more and more smart products have entered people's lives, and the functions of smart products are rich and varied. For example, people can measure their height through smart products equipped with cameras. [0003] In the existing height measurement scheme, the user stands in front of the background with the height scale line drawn, takes a picture through the camera, and then recognizes the scale of the scale through the image recognition algorithm, and then obtains the height of the human body. [0004] However, in the prior art, in order to measure the height, the user needs to prepare a ruler, which is inconvenient. Contents of the invention [0005] The invention provides a human body height measurement method, device and smart mirror, so as to meas...
