Problems solved by technology

The former has made great progress and is now the mainstream implementation method, but based on RGB images, it is easily disturbed by external factors such as illumination changes, shadows, object occlusions, and complex backgrounds, which greatly reduces the detection performance.

Embodiment 1

[0050] This embodiment provides a method for measuring a human body based on images, including:

[0051] Extract feature points in the color map;

[0052] Measure the level of the belly button;

[0053] Calculate the distance from the navel to the coronal plane;

[0054] Calculate and measure the "hip width", "height", "waist width", "waist circumference", "chest width", "weight", "hip circumference", "chest circumference" and "shoulder width" of the human body;

[0055] Camera pitch angle calibration.

[0056] In a preferred embodiment, extracting the feature points in the color map in this implementation includes extracting the eyes and the tip of the chin, and the distance between the connecting line of the eyes and the tip of the chin is defined as one-half of the head length.

[0057] In a preferred embodiment, in this implementation, the horizontal position of the navel is measured, and the third "head length" position from the top of the head is estimated to be the position of the ...

Abstract

The invention provides an image-based human body measuring method. The image-based human body measuring method includes the steps: extracting the characteristic points in a color image; measuring thehorizontal position of a navel; calculating the distance from the navel to a coronal plane; calculating and measuring the hip breadth, the height, the waist breadth, the waistline, the breast breadth,the body weight, the hip circumference, the chest circumference and the shoulder breadth of a human body; and calibrating the pitch angle of a camera. The image-based human body measuring method andsystem has the advantages of being high in the image acquisition speed, being able to quickly complete human body measurement, having no radioactive substance during the image acquisition process, having no harm for the human body (compared with medical science or arranging a human body for acquisition), having no demand for being naked or approximately naked dressing, thus being able to protect privacy, having no demand for completing acquisition measurement in an enclosed environment, saving the dimensional space and being able to comfort the mentality of the measured personnel.

Description

Technical field [0001] The present invention relates to the field of image processing, in particular to a method and system for measuring human body based on images. Background technique [0002] With the development of computer graphics and other information processing technologies, anthropometrics has attracted much attention as a research point and frontier direction in the field of computer graphics. It is used in robot vision, advanced human-computer interaction, virtual reality, virtual try-on, virtual social, fitness Health, ancestry analysis (genophenotype) and other aspects have been widely used and promoted. [0003] At present, according to the type of image, human body measurement can be divided into two categories: detection based on RGB image and detection based on depth image. The former has made great progress and is now a more mainstream implementation method. However, RGB-based images are susceptible to interference from external factors such as illumination chan...
