Embodiment Construction

[0020] like figure 1 As shown, the automatic retinal imaging system includes a retinal imaging optical system A, a support structure B and a central processing unit C located inside the support structure. The system also includes a stepping motor, and the activities of the stepping motor and the retinal imaging optical system A Components are connected. The support structure B includes a headrest, a sensor switch D and a camera stand. The headrest is used to provide head support for the inspected person, and the sensor switch D is installed on the chin position of the inspected person on the headrest, and the sensor switch D provides a starting signal for the central processing unit C; the camera seat is used to fix the camera and can automatically control the camera Move in three directions: front and back, left and right, and up and down.

[0021] like figure 2 As shown, the retinal imaging optical system A includes three necessary components: alignment optical path, foc...

Abstract

The invention discloses an automatic retina imaging system, belongs to the fields of medical optical instruments and biological recognition, and provides the automatic retina imaging system for solving the problem of incapability of realizing automatic operation existing in the conventional retina imaging technology. The system comprises a retina imaging optical system, a step motor, a supporting frame and a central processing unit, wherein the retina imaging optical system comprises an alignment optical path, a focusing and positioning optical path and a lighting and imaging optical path; the supporting frame comprises a head support, an inductive switch and a camera seat; and the central processing unit comprises a power supply, a CPU (Central Processing Unit), a step motor driver and an image acquisition card. The automatic retina imaging system has a simple optical machine structure; photographing of a retina picture can be automatically finished; and the automatic retina imaging system is widely applied to the fields of medical treatment, biological recognition technology and the like through internet.

Description

technical field [0001] The invention relates to an automatic retinal imaging system, which belongs to the fields of medical optical instruments and biological identification. Background technique [0002] Retinal imaging technology is gradually being widely used in fields such as medical treatment and biometric technology. In medicine, timely detection and tracking of retinopathy can play an effective role in diagnosis and early warning of various diseases. In the field of biometrics, the retina has far more biological characteristics than fingerprints and palmprints, which can greatly improve the recognition accuracy; moreover, the retina penetrates into the fundus of the eye and is not easy to be obtained by the outside world, so it has a very high level of confidentiality. [0003] Retinal imaging technology has a long research history, but still cannot meet the needs of society. For example, in the medical field, with the development of the Internet, the telemedicine s...
