Problems solved by technology

[0002] In the prior art, imaging the interior of objects, especially the interior of the human body, has the outstanding advantages of being non-destructive, non-invasive, and non-radiative through light, but so far there is no mammary gland transmission imaging optical measurement system that can be used at home for frequent tumors Self-inspection, the reason is that the existing breast imaging measurement system has high cost, complex operation, and limited accuracy, which cannot meet the needs of breast self-inspection in practical applications

Abstract

The invention discloses a square-wave frequency coding high-spectral imaging measurement system for mammary glands. The square-wave frequency coding high-spectral imaging measurement system is characterized in that a monochromatic light source group is distributed on one side of a mammary gland tissue sample, and a camera is distributed on the other side of the mammary gland tissue sample; various monochromatic light sources in the monochromatic light source group are densely arrayed on a hemispherical surface, and a light beam can be gathered by a lens to form a light source; a light source receiving device can be formed by the camera; the various monochromatic light sources in the monochromatic light source group can be respectively driven by square waves which have different frequencies in two-times ratio relations with one another, each pixel point in each image received by the camera is a monochromatic light combination of the corresponding monochromatic light source, and the monochromatic light combinations are transmitted through the mammary glands; the monochromatic light combinations are separated from one another by a computer, so that contribution of the various monochromatic light sources on the monochromatic light combinations can be obtained, and transmission high-spectral images of the mammary glands can be formed according to the contribution. The square-wave frequency coding high-spectral imaging measurement system has the advantages that the transmission high-speed, high-information and high-spectral images of the mammary glands can be precisely measured, the square-wave frequency coding high-spectral imaging measurement system is low in cost, convenient to apply and suitable for regular self-examination at home, and the like.

Description

Technical field [0001] The invention relates to the field of imaging measurement systems, in particular to a hyperspectral image imaging measurement system applied to the mammary gland with square wave frequency coding. Background technique [0002] In the prior art, imaging the inside of an object by light, especially the inside of the human body, has the outstanding advantages of non-destructive, non-invasive and non-radiation, but there is no breast transmission imaging light measurement system that can be used in the home for frequent tumors. The reason for self-inspection is that the existing breast imaging measurement system has high cost, complex calculation, and limited accuracy, which cannot meet the needs of breast self-inspection in practical applications. Summary of the invention [0003] The present invention provides a square wave frequency encoding hyperspectral image imaging measurement system applied to the breast. The present invention realizes high-speed, large-...
