Adjusting method and device for working distance of colposcope

Abstract

The invention is suitable for the technical field of medical equipment and provides an adjusting method and device for the working distance of a colposcope. The method comprises the steps that a lens of the colposcope is controlled to collect an image; the collected image is subjected to brightness uniformity analysis so as to determine whether the brightness uniformity of the collected image meets a preset condition or not; if the brightness uniformity of the collected image does not meet the preset condition, the working distance of the colposcope is adjusted by a preset distance value, and the operation of controlling the lens of the colposcope to collect an image is carried out again until the brightness uniformity of the collected image meets the preset condition. It is ensured that the imaging effect of the colposcope is clear, and the working distance of the colposcope does not need to be manually adjusted by medical personnel in the whole process, so that the operation efficiency of the colposcope is improved, and the accuracy of information determination is improved through the clear image.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a method and a device for adjusting the working distance of a colposcope. Background technique [0002] Colposcopy is widely used in the early diagnosis of reproductive tract diseases and cervical cancer. It magnifies the images of the cervix, vagina and vulva by a certain number of times. Under the illumination of the light source, medical staff can observe what the naked eye cannot see Epithelial and vascular changes. Diseases that can be detected by colposcopy include cervical erosions, cervical polyps, intraepithelial neoplasia, cervical cancer, vaginitis, sarcoid virus infection of the vulva or vagina or cervix, and subclinical papillomavirus infection, which is not only in the cervix It has important application value in the diagnosis of early cancer diagnosis and discrimination of tumor and inflammation. At the same time, it also has special applicat...
