Follicular puncture detection method based on near-infrared vision

Abstract

The invention discloses a follicle puncture detection method based on near-infrared vision. The follicle puncture detection method comprises the following steps: firstly, grabbing a follicle punctureoperation surface by a near-infrared camera, wherein the operation surface comprises a follicle to be injected and an injection tube carrying sperms, and realizing injection tube calibration accordingto the fact that the injection tube carrying the sperms is a unique moving object in the operation surface; and determining an intersection point with follicular zona pellucida along the moving direction of the calibrated injection tube, determining an expected position of a position identifier according to the intersection point, and finally completing detection according to whether the positionidentifier appears at the expected position. Position identification is set in a self-adaptive mode according to the light and shade difference of gray level images of the zona pellucida, substancesin the zona pellucida, the sperms in the injection needle and seminal plasma under near-infrared light, follicle puncture is judged to be successful when the position identification appears in the visual field, and automatic control injection is achieved. In an in-vitro fertilization and embryo transplantation combined technology, the puncture effect can be effectively stabilized and the success rate of one-time puncture injection can be improved by means of injecting single sperms in egg pulp.

Description

technical field [0001] The invention belongs to the technical field of computer vision target detection, in particular to a near-infrared vision-based follicle puncture detection method. Background technique [0002] In vitro fertilization combined with embryo transfer technology, also known as test-tube baby, refers to taking out eggs and sperm respectively, placing them in test tubes to fertilize them, and then transferring embryo precursors (fertilized eggs) back into the mother's uterus to develop into fetuses. Test-tube babies are babies born by artificially fertilizing eggs and sperm outside the body and carrying out early embryonic development, and then transplanting them into the mother's womb. The first-generation test-tube baby technology, which puts sperm and eggs outside the body and uses various techniques to fertilize the eggs, solves infertility caused by female factors; Infertility problems caused by factors; with the development of molecular biology, on the...

Problems solved by technology

The operation efficiency is low and individual differences are huge. The world average pregnancy rate of in vitro fertilization combined with embryo transfer technology is only 25.1%, and the fertility rate is 18.5%.
