Description

Color blind meter and color blind detection method

The invention relates to the field of color blind detection, and more particularly to a color blind meter and a color blind detection method. Background technique

At present, most of the color blind detection work still relies on traditional book detection, and relies on physician-assisted detection and judgment to complete. These test books, charts, and a series of traditional color discrimination checkers, slideshows, and color-blind inspection mirrors all have large errors in detection results and are inferior in accuracy.

Color blind detection instruments and books, different principles, different detection methods, and most instruments must be

Detective assistance is required to complete the test.

When the traditional method is used for testing, the test subject is extremely easily interfered by the physician and the peripheral physical environment, and the test result cannot accurately reflect the color vision health status of the test subject, which is greatly affected by subjective factors. And among the many detection methods, because of the differences between the detection standards and the methods themselves, the versatility and scientificity are poor, and because of the geographical and cultural limitations and the level of education of the subjects themselves, the test results are also Brought the impact.

Summary of the invention

The invention provides a color blind meter and a color blind detection method, the purpose of which is to abandon the traditional detection method and the detection mode, so that the test subject can independently complete the color vision detection according to the displayed picture under the program of the instrument, without the assistance of the physician. It eliminates the influence of factors such as geographical and cultural differences and the educational level of the testees on the test. At the same time, the judgment of the test results is completed without the help of the physician, and the diagnosis error caused by the difference in the doctor's ability is excluded.

The specific technical solution of the present invention is as follows: A color blind meter comprising: an input device, an output device and a power adapter, the color blind meter further comprising:

If yes, the system directly saves and prints the relevant results; if not, the second detection phase is performed, the color blind meter randomly displays four detection images, and judges the color blind type according to the actual response of the tester, and finally the system saves and prints the relevant results.

The method of detecting color blindness includes more specifically the following steps:

Step S100: The color blind meter is powered on, that is, the system is turned on to prepare for testing;

Step S200: The color blind meter is initialized and enters the standard light source display mode. The testee inputs the identification information and the detection number to start the detection. When the detection starts, the operation prompt is displayed according to the predetermined setting, and the prompt is kept for 30 seconds;

Step S300: After the operation prompt display ends, the method enters the first stage, and displays twenty color blind detection pictures, wherein each color blind detection picture is recognized by the test subject when randomly displayed; Step S400: First At the end of the stage, the color blind meter makes a logical judgment based on the recognition of the picture by the person under test, and judges whether the subject is normal, weak or full color blind and full color weak if the judgment result is normal, weak or full color blind and full color weak. , then proceeds to step S500, otherwise proceeds to step S600;

Step S500: The color blind meter outputs a judgment result output command to the output device, and the color blind meter saves the detection result to an external memory (such as a USB flash drive);

Step S600: The method enters the second stage, and randomly displays four standard color blind detection pictures, wherein each color blind detection picture is recognized by the test subject when randomly displayed;

Step S700: After the second stage, the color blind meter makes a logical judgment based on the recognition of the picture by the test subject, and judges the color blind type of the test subject. After the judgment is over, the process returns to step S500.

As shown in Figure 7, the first stage system detects the logic diagram, and the system corrects the rate based on the detection answer. Line probability analysis. In the first stage, in the 21 answer cards, if the answer is four or less, the system judges as "your color vision is normal"; if the answer is more than four to seven or less, the system judges as "you The color vision is between normal and abnormal. It is recommended to consult an ophthalmologist, that is, the color is weak; only the number "12" can be recognized, and the rest are unrecognizable, then the system judges "full color blindness and full color weakness"; If the page is above or all is wrong, the system determines to enter the second stage detection. Among them, unrecognized means that normal people are unrecognizable, and abnormal people can see numbers.

As shown in Figure 8, the second-stage system detects the logic diagram. The color-blind meter displays four color-blind detection pictures of the numbers "13", "51", "49", and "85", if the single-digit and tens digits can If all are correctly identified, the color blindness is judged as "red-green blind; if the ten-digit number of the image is accurately recognized, and the numbers in the three or more pictures are accurately recognized, the color blindness is judged as "green blind"; if the picture is The number of digits is accurately identified, and the numbers in more than three pictures are accurately identified, then the color blind meter is judged as "red blind"; if the tens digits in any two pictures are accurately identified, the other two pictures are If the single digits are consistent, the color blindness is judged as "slight red-green blindness".

The first stage of the above picture is not limited to 21 pictures, and the second stage is not limited to 4 pieces; the content of the picture is not limited to the numbers listed in this embodiment, and may be other numbers or figures. As long as it is the method, it is the scope of protection of the present invention. The above is only the preferred embodiment of the present invention and the technical principles of the present invention. Any changes or substitutions that can be easily conceived within the technical scope of the present invention should be covered by the protection of the present invention. Within the scope.
