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...
