Measuring method and measuring device for height of human body based on binocular vision technique

Abstract

The invention relates to the technical field of computer vision and discloses a measuring method and a measuring device for the height of a human body based on a binocular vision technique. According to the measuring method and the measuring device disclosed by the invention, the height of a human body target is measured by acquiring image coordinates of a human head sharp point of the human body target in a scene image shot by a binocular camera and depth information corresponding to the image coordinates and calculating world coordinates of the human head sharp point under a coordinate system of the camera. According to the measuring method and the measuring device, the requirement on the compatibility of a measured person is low, and the height measurement can be finished by a mode that the person stands within the measurable range for shooting by the camera; the body heights of multiple persons in the scene can be simultaneously measured; in addition, the measurement precision is higher.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to a human body height measurement technology based on binocular vision technology. Background technique [0002] Computer vision is a simulation of biological vision using computers and related equipment. Its main task is to obtain 3D information of the corresponding scene by processing the collected pictures or videos, just like humans and many other creatures do every day. [0003] Binocular vision technology is an important form of computer vision. It is based on the principle of parallax and uses two cameras in different positions to shoot the same scene. Through binocular positioning and matching technology, the three-dimensional information of the target in the scene is obtained. Binocular calibration refers to establishing the relationship between the pixel position of the camera image and the position of the scene point according to the camera model, and solving th...

Problems solved by technology

[0004] The inventors of the present invention have found that the existing human body height measurement is limited to the contact measurement with equipment, and requires the cooperation of itself to measure the human body height more accurately, such as caliper measurement and ultrasonic induction height measuring instrument. It can only be completed on the platform specified by the device, and can only be measured one by one
