Embodiment Construction

[0018] Such as figure 1 As shown, the present embodiment is composed of a computer 1 , an image acquisition card 4 , a camera 2 , a sound box 3 , a wireless operating device 5 , and a printer 6 . Among them, the computer is equipped with detection software developed by VC++ language, and the operating system is as follows: figure 2 as follows:

[0019] 1. Prompt voice playback

[0020] Build a prompt voice library, which consists of several pre-recorded voice files and content description files. Each prompt generates a windows WAV file, and the sound playback function BOOLsndPlaySound (LPCSTR lpszSound, UINT fuSound) is automatically called by VC++ language in the software, wherein the parameter lpszSound is the path and file name of the prompt voice WAV file in the voice library.

[0021] The playback sequence is selected and set by the medical staff through the detection process setting interface provided by the software according to the content description of the voice ...

Abstract

A vision test system based on computer and multimedia technique for testing the vision and the chromatic discrimination power of human eye is composed of computer, image pick-up card, camera head, sound enclosure, wireless operator and printer. Its test method includes such steps as automatically and randomly generating E or C characters and choosing the chromatic patterns by system, providing their answers by a person to be tested via wireless operator, and judging the vision and chromatic discrimination powder of the person by system.

Description

technical field [0001] The invention belongs to medical detection equipment, relates to computer image processing technology and computer voice processing technology, in particular to a vision detection device and detection method based on computer multimedia technology, which can be used to detect the vision and color discrimination of human eyes. Background technique [0002] At present, when medical and health institutions in my country conduct visual acuity examinations, they mainly use logarithmic vision charts and color blindness detection maps, which are manually carried out by medical staff. The test results are easily affected by subjective factors, and there will be a phenomenon of looking for people with normal vision to take the test. . In recent years, there have been reports of automatic detection devices using computer technology, but they mainly focus on the automatic generation of detection characters and detection patterns. For example, the "Visual Detector"...
