A device and method for detecting human meibomian gland model based on multi-spectrum

Abstract

The invention provides a device for detecting a human eye meibomian gland model based on multispectrum and a method thereof, and relates to a medical optical detection device. The device for detecting a human eye meibomian gland model based on multispectrum is provided with a light source module, a control module, an image acquisition module, and an image processing module. The light source module is a multispectrum light source. Light emitted by the light source module passes a light filter group which is internally arranged in the light source module, the control module switches light filters, and light in specific central wavelength is output and irradiate human eyes. The image acquisition module comprises a camera unit and a microscopic unit, and the module is used to obtain meibomian gland images in the specific central wavelength and the images are input to the image processing module. The image processing module is provided with a separation algorithm, and analyzes and processes the meibomian gland images transmitted from the image acquisition module, to improve contrast of the meibomian gland images, and gland morphological parameters are calculated. The device distinguishes a meibomian gland and peripheral tissues, and the structure of the meibomian gland can be clearly observed.

Description

technical field [0001] The invention relates to a medical optical detection device, in particular to a device and method for detecting a human meibomian gland model based on multi-spectrum. Background technique [0002] The meibomian gland is a special differentiated sebaceous gland located in the tarsus of the eyelid, arranged vertically with the opening and the eyelid margin, and the lipid secretion discharged is evenly coated on the surface of the tear film through the blinking movement of the eyelid to form the tear film The outermost layer plays an important role in maintaining the health of the ocular surface: it can effectively delay the evaporation of the tear film water layer, reduce the surface tension of the tear film, enhance the stability of the tear film, prevent the skin of the eyelid margin from being soaked by tears, and provide smooth and smooth optics. Interface to reduce damage from blinking and act as a barrier to prevent contamination of the tear film w...

Problems solved by technology

Since the meibomian glands need to penetrate the conjunctiva and epithelial cells, single-wavelength infrared rays are often not optimal for some images, resulting in poor contrast and blurred boundaries between the glands and surrounding tissues.

The environment and artificial interference are relatively large, and there is a lack of definite image processing algorithms and hardware conditions to match
