Problems solved by technology

[0003] OCT equipment needs to align the main optical axis of the instrument's optical path with the pupil or corneal apex of the human eye, and this alignment process takes up a lot of working time of the OCT equipment. On the other hand, there is a problem of repeatedly using iris recognition to align the pupil for reexamination patients , so it is urgent to improve the efficiency of OCT equipment to receive patients

Embodiment Construction

[0023] The following is a clear and complete description of the technical solutions in the embodiments of the present invention with reference to the drawings and embodiments. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them.

[0024] OCT equipment is used to collect the fundus information of the whole human eye, and generate the fundus cross-sectional image of the human eye and the blood vessel image of the human eye. figure 1 The structure block diagram of the OCT equipment shown is taken as an example for illustration. Since the system of the present invention is used for auxiliary adjustment of the OCT equipment, only understanding the structure of the OCT equipment is beneficial to the elaboration of the system of the present invention. OCT equipment generates images by scanning the eyeball of the human eye through a linear camera. The linear camera scanning path starts from the light source 101. After the ligh...

Abstract

The invention provides a system and a method for accelerating alignment of an OCT apparatus and human eyes through iris recognition. In an initial state of OCT scanning, the distance between human eyes and a lens is evaluated initially; whether the scanning distance is long or not can be judged according to the quality of an image of iris recognition of a single camera, and information of a patient is extracted; the process allows dynamic adjustment via a motor; when the iris image is identified, the position of the human eyes relative to the OCT apparatus can be changed by adjusting a stepping motor. The distance between OCT and human eyes is initially identified and the initial alignment speed of the OCT apparatus is increased; the information of patients can be extracted rapidly and theeffect of adjusting the alignment function of the OCT apparatus intelligently is achieved.

Description

technical field [0001] The invention relates to the field of optical coherence tomography, in particular to a system and method for accelerating the alignment of OCT equipment and human eyes through iris recognition. Background technique [0002] Optical coherence tomography (OCT, Optical Coherence Tomography) is an emerging optical imaging technology. Compared with traditional clinical imaging methods, it has the advantages of high resolution, imaging speed, no radiation damage, moderate price, and compact structure. An important potential tool for basic medical research and clinical diagnostic applications. Currently, among various ophthalmic devices using optical instruments, an OCT device for ophthalmic examination and treatment has become an indispensable ophthalmic device for ophthalmic disease diagnosis. [0003] OCT equipment needs to align the main optical axis of the instrument's optical path with the pupil or corneal apex of the human eye, and this alignment proc...
