Embodiment 1

[0031] Such as Figure 2 to Figure 6 As shown, the present embodiment provides a height measurement system, which includes:

[0032] an image acquisition unit, configured to acquire a depth image;

[0033] The processing unit is configured to analyze the ground and the top of the human head in the depth image, and calculate the distance between the top of the human body and the plane of the ground as the height.

[0034] That is to say, the height measurement system of this embodiment includes an image acquisition unit, which can acquire depth images of the human body and the ground to be measured. Depth is a "stereoscopic" image, in which not only the color information of each pixel is recorded, but also the distance and relative angle between each pixel and the image acquisition unit, so that the relative position of each pixel in space can be determined. Thus, the processing unit can analyze which pixels in the depth image are the human body and which are the ground. Aft...

Embodiment 2

[0057] Such as Figure 2 to Figure 6 As shown, the present embodiment provides a height measurement method, which includes:

[0058] Get the depth image;

[0059] Analyze the ground and the top of the human head in the depth image, and calculate the distance between the top of the human body and the plane where the ground is located as the height.

[0060] That is to say, the height measurement method in this embodiment is the method performed by the height measurement system in the above embodiment.

[0061] Specifically, such as figure 2 As shown, the height measurement method of the present embodiment may include the following steps:

[0062] S1. Acquire a depth image.

[0063] S2. Analyze the depth image of the current frame to see if the ground can be obtained; if it can be obtained, proceed to the next step; if not, analyze the depth image of the previous frame (the above frame as an example) to obtain the ground.

[0064] S3. Fitting to obtain the ground equation....

Abstract

Disclosed is a height measuring system and method. The height measuring system of the disclosure comprises an image obtaining unit configured to obtaining a depth image and a processing unit configured to analyze and determine a ground and a top of a head of a human body in the depth image and calculating a distance between the top of the head of the human body and a plane of the ground as a height.

Description

technical field [0001] The invention belongs to the technical field of height measurement, and in particular relates to a height measurement system and method. Background technique [0002] The traditional height measurement method is to use a ruler, etc., which requires the cooperation of people, and cannot achieve real-time measurement. [0003] In the prior art, there is also the technology of obtaining height by collecting and analyzing human body images. This measurement method does not require human cooperation, as long as the person walks within the image collection range, real-time measurement can be realized. [0004] An existing height measurement method includes analyzing the feet and the top of the head of the human body in the image, and taking the distance between the two as the height. However, the disadvantage of this method is that the feet of the human body tend to adhere to the ground, which is difficult to obtain accurately and affects the measurement ac...
