Description

Optical medical body shape measuring instrument and its measuring method

technical field

The invention relates to a physical examination device and a measuring method thereof, in particular to an optical medical body shape measuring instrument and a measuring method thereof.

Background technique

The "new measurements" of the human body are neck circumference, waist circumference, and waist-to-hip ratio; the correlation between the waist/hip ratio and human health is much higher than that between BMI and body composition. The world's medical community has recognized that the "new measurements" of the human body have a clear statistical correspondence with certain diseases. Paying attention to the "new measurements" can help people control their weight and greatly reduce the risk of cardiovascular and cerebrovascular diseases. If health guidance is given in combination with other human body parameter values such as "new measurements" and BMI values during the health checkup, it will allow people to manage their health more conveniently.

None of the measuring instruments in the prior art can measure and give three-dimensional body contour information, neck circumference, waist circumference and waist-to-hip ratio. The measurements of the "new measurements" are all done manually, using a tape measure to measure the neck circumference, waist circumference and hip circumference, and calculate the waist/hip ratio. This measurement method has problems such as high labor intensity, uncivilized and inaccurate measurement, and it also has a huge gap with the automatic measurement method of parameters such as height and weight.

The annular measuring mechanism continuously measures the body surface during movement.

A plurality of optical sensors are evenly distributed on the annular measuring mechanism, and a coordinate system is established with the intersection of the vertical line of the measuring center of the annular measuring mechanism and the surface of the chassis as the coordinate origin. At a certain moment in the motion process, the z-axis coordinates of the optical sensor can be obtained through the information fed back by the encoder, and the x and y-axis coordinates of the optical sensor and the pointing direction measured by the optical sensor are known. During actual measurement, the optical sensor measures the distance between the detection point on the body surface of the person being measured and the optical sensor, and the three-dimensional coordinates of the detection point on the body surface of the person being measured can be obtained through mathematical derivation based on the above information. The three-dimensional body contour information of the measured person can be obtained by synthesizing the three-dimensional coordinates of all the detected points on the body surface of the measured person.

The new three-dimensional values (neck circumference, waist circumference and waist-to-hip ratio) and other body shape information such as height and bust are extracted from the three-dimensional body contour information of the measured person through intelligent algorithms such as pattern recognition, and the measurement results are given through the display.
