Example Embodiment

[0031] The hardware platform of the visual measurement system and method with the features of digital optotype and voice recognition is composed of optotype display unit, audio collection unit, and detection data processing unit. The detection data processing unit is connected with the visual mark display unit through a video port and a video line. The optotype display unit can be replaced by an LCD TV for displaying digital optotype signals. The audio collection unit is connected to the detection data processing unit through the audio cable and the audio collection port of the computer. Keep a specified distance of 5m between the subject and the optotype display unit (LCD TV), and send a letter in Chinese to read out the digital optotype. The visual measurement system interface with digital visual mark and voice recognition features disclosed in the present invention is as follows figure 1 Shown.

[0032] The visual mark display unit, the subject, the voice acquisition unit an...

Abstract

The invention discloses a visual measuring system having digital sighting target and voice recognition characteristics, which is applied to a visual measuring method supported by a multimedia system of a computer. A core technique is that a sighting target display unit, a voice collection unit and a measured data processing unit constitute circular processing procedures of collection, calculation and control and the like about vision test data. Every time, the dimension of five numbers 3, 5, 6, 8 and 9 in stochastic transformation appears on the sighting target display unit. The size of the sighting target is matched with an international vision test standard of a logarithm system. A testee reads the observed digital sighting target according to self-vision; after the voice collection unit sends test data to the multimedia data processing unit for circular processing, a real vision value of a tested person is obtained. The visual measuring system having the digital sighting target and voice recognition characteristics increases the interestingness of a vision test process, simplifies vision measurement procedures, and generates good stimulus response to vision care, with contributions to people for protection on vision health.

Description

technical field [0001] The invention discloses a visual measurement system and method with digital visual mark and voice recognition features. Its content involves the fields of international standard vision detection methods, computer multimedia technology and Internet of Things application technology. Background technique [0002] The normal development of the human eye is from oblate to round, from short to long, from small to large, from high hypermetropia to emmetropia. Before the age of 6 is the rapid development of vision: the eyes of newborn babies are mostly flat and round, which are much shorter than those of adults, so they are in a state of high hyperopia, so their vision is very weak, and they can only distinguish between light and shadow; At one year old after birth, they can only distinguish relatively large objects at close distances; at the age of 1-5, the eyeballs develop very rapidly, and their volume and front-to-back diameter increase and elongate signi...
