Measurement condition reproducing device and method based on body's surface texture characteristic and contact pressure

Abstract

In the present invention, the equipment consists of optical fiber measuring head, X, Y and Z axis linear displacement and Z axis angular servo positioner, carrying table, lighter, camera, image collecting card, spectral detection system and computer processing system, also set contact pressure sensor, temperature sensor and pressure and temperature signal processing and collecting unit. The method includes the steps of: image pick-up, matching and positioning of body's surface texture characteristic; displacement in X-Y plane and Z axis rotation positioning based on image matching; positioning in Z axis direction based on measurement elements and body's surface texture; and image collection and monitoring the motion state of the measured parts.

Description

technical field [0001] The invention relates to a measurement device and method, in particular to a measurement condition reappearance device and method based on human body surface or surface texture characteristics and contact pressure. Background technique [0002] In the process of non-invasive infrared spectrum detection of human body components (such as: blood sugar concentration, etc.), due to the differences in human tissue structure, such as skin tissue and thickness, blood vessel distribution, fat composition and thickness, etc., and fluctuations in the external environment, It is required that the measurement conditions such as the measurement site and contact pressure be kept constant. [0003] In a detection system based on infrared spectroscopy, even if the content of a certain component to be tested in the human body is basically constant, the spectral measurement data of different human bodies or different parts of the same human body m...

AI Technical Summary

Problems solved by technology

[0005] (1) It cannot automatically and effectively identify whether the measured object is the same individual, and human intervention is necessary;

[0006] (2) The reproduction accuracy of the measurement position is low, the highest can only reach the pixel level;

[0007] (3) The contact pressure of the measurement site is not considered when the measurement conditions are reproduced;

[0008] (4) There is no effective solution to the rotation phenomenon of the measurement part;

[0009] (5) The measurement error caused by the movement of the measurement part during the measurement process cannot be considered and resolved
