Problems solved by technology
[0004] The main problem of color recognition based on TCS230 is the limited measurement distance (the best measurement value is only 2-3 cm), which is mainly due to the interference of ambient light and the difficulty in collecting reflected light from the target object. Therefore, TCS230 is directly used For color recognition, it cannot meet the needs of red-green color blindness patients in daily life and work in terms of recognition distance

The invention discloses an intelligent wristband for assisting achromate in discriminating colors. The intelligent wristband comprises a wristband body and a color discrimination device arranged on the wristband body and used for assisting the achromate; the color discrimination device comprises a convex lens, a flash lamp, a controller, a power supply circuit and a display screen; the controller is respectively connected with a color sensor, the flash lamp, the power supply circuit and the display screen; the convex lens is arranged at the front end of the color sensor according to a focal position; an internal program in the controller automatically performs white balance settings; the flash lamp is used for irradiating a target object under test through the convex lens; after passing through a condensation light path, the reflected light of the object under test is irradiated onto the color sensor; after an output signal of the color sensor is recognized by the controller, an identified result is transmitted to the display screen, and therefore the wearable equipment for assisting achromate in discriminating the colors is realized, the color discrimination distance is increased, and the misjudgment rate of color discrimination is effectively reduced. The invention also discloses a color discrimination method of the intelligent wristband for assisting the achromate in discriminating the colors, so that the goal that the wearable equipment assists the achromate in discriminating the colors is achieved.
Description
technical field [0001] The invention relates to an intelligent electronic device, in particular to an intelligent bracelet and a color identification method for assisting color-blind patients in color identification. Background technique [0002] Red-green color blindness is a genetic disease, which cannot be cured even today with advanced medical science. This kind of people are very depressed, and their work and life are restricted for this reason. The only way at present is to help patients identify colors with the help of purely optical lenses. And the report that assists red-green color-blindness patient to distinguish color by means of electronic equipment has not been seen yet. Therefore, we use color sensors to prepare smart color-discrimination bracelets, which can be used to assist red-green color blindness patients to accurately distinguish between red and green. This is the first wearable device that assists red-green color blindness patients in color discrimina...
