Abstract

The invention discloses a vision detection system. The system comprises a display body (10) which comprises a first surface (10a), and symbols (11a) used for detecting eyesight are arranged on the first surface (10a); an image acquisition device (21) is arranged on the first surface (10a) of the display body (10) and is used for acquiring an image of a target user in front of the visual chart; a processing device (22) is connected to the image acquisition device (21) and is used for comparing the images acquired by the image acquisition device (21) with a plurality of preset face images to determine identities corresponding to the acquired images; the processing device (22) is further used for determining vision parameters of the user according to feedback of the user; and a storage deviceis used for storing the identity information and the vision parameters corresponding to the acquired images. According to the scheme, the identity information and the vision parameters of the user can be stored, subsequent calling and comparison are facilitated, and customization of vision detection of the target user is achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a vision detection system. Background technique [0002] There are many kinds of medical equipment, and the equipment that is often used in the eye chart box in the ophthalmic testing instrument. The purpose of the eye chart box is to provide measurement channels for the vision tester to achieve the function of visual acuity detection. The traditional eye chart box includes a box body, an eye chart on the surface of the box, and a fluorescent lamp located in the box. After the fluorescent lamp is energized, the box is illuminated, and the eye chart on the surface of the box is highlighted to complete the detection of human vision. Such a structure is simple, and the detection process can be realized by powering on, so it is widely used in detection. [0003] At present, the vision chart light box is mostly used as a carrier for the vision chart detection device, and the function of displ...
