Spatial self-positioning ophthalmic optical coherence tomography system

Abstract

The invention provides a spatial self-positioning ophthalmic optical coherence tomography system which comprises a first depth camera, a second depth camera, an RGB camera, a mechanical arm, a main control mechanism, an OCT scanning probe and a machine shell, the main control mechanism is installed in the machine shell, is in signal connection with the mechanical arm and is used for driving the mechanical arm, the first depth camera is installed on the machine shell, one end of the mechanical arm is installed on the machine shell, the other end of the mechanical arm is in driving connection with the OCT scanning probe, and the second depth camera and the RGB camera are both installed on the OCT scanning probe. A human face, human eye and pupil three-level positioning mode is adopted, the depth camera and the RGB camera are used as a visual servo positioning system for three-level positioning of the mechanical arm, target human eyes are recognized and tracked in real time, positioning is accurate, performance is reliable, manpower is replaced with the mechanical arm, the automation degree is high, the operation difficulty of doctors is lowered, the examination efficiency is improved, and the spatial self-positioning ophthalmic optical coherence tomography system can be suitable for a scene in which a traditional table type ophthalmology OCT instrument cannot be used.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a space self-positioning ophthalmic optical coherence tomography system. Background technique [0002] Optical coherence tomography (OCT) is an emerging non-contact, non-invasive imaging technology with the technical advantages of high resolution and high imaging speed. Tomographic imaging of the tissue is performed based on the difference in its scattering ability to clearly distinguish the tissue structure. [0003] At present, the ophthalmic OCT examination equipment used clinically is desktop type, and the application scenarios and crowds are limited. On the one hand, the subject needs to use the forehead rest to fix the head and sit in front of the device to be examined. On the other hand, the equipment needs to rely on skilled operators. The eyes of the patient will move during the examination. It takes a long time for the doctor to manually calibrate and focus th...
