The vision screening instrument 1 provides an objective detection result by means of an eccentric photography principle, can quickly output the result for 1s, can greatly shorten the time for detecting the vision, and can compare the result with a subjective measurement result provided by the vision inspection instrument 2 to further help a tester to obtain more accurate vision conditions. When the eccentric photography function of the vision screening instrument 1 is selected, the eccentric infrared lamps are turned on in a certain sequence to illuminate human eyes, the central camera 5 captures an image sequence and transmits the image sequence to the image analysis processing system for processing, relevant parameters such as refraction and astigmatism, interpupillary distance, pupil size, strabismus and the like of the eye to be inspected are calculated, and results are recorded and a report is generated.
The vision tester 2 can automatically calculate the size of the sighting target according to the distance between a tester, the sighting target unit and the equipment, and randomly generate the sighting target direction, so that the measurement result is more objective and reliable. The image processing module 6 acquires binocular images by using the two cameras 5, intelligently detects the positions of eyes in the binocular images by an AI neural network algorithm, and calculates the distance between the eyes of the tester and the equipment. Because the working distances of the vision screening instrument 1 and the vision inspection instrument 2 are different, the fixed distance between the vision screening instrument 1 and a tester is 1m, the working distance between the vision inspection instrument 2 and the tester is 2m-7m, the image processing module 6 can detect the distance between the current equipment and the tester, and can prompt the tester to be close to a little or far from a little by voice according to different functions and target distances to guide the tester to reach a proper target position. The AI neural network algorithm intelligently detects the position of the eyes of the tester, judges whether the equipment and the eyes of the tester are at the same height, and automatically adjusts the height position of the equipment if the equipment and the eyes of the tester are not at the same height, if the tester selects the measurement function of the vision tester 2, the center of the screen of the vision tester 2 and the eyes of the user are adjusted to be at the same horizontal plane. When the tester selects the eccentric photography function of the vision screening instrument 1, the center of the camera 5 of the vision screening instrument 1 slides downwards or upwards to the same horizontal plane with the eyes of the user. The vision tester 2 is provided with a case management system, and each person needs to create a new case for the first use by a mode including but not limited to card swiping or code scanning, and simultaneously records the face picture of the tester. Then, when the tester stands in front of the vision inspection tester 2 again, the image processing module 6 collects face images, the AI neural network algorithm identifies faces, and the system automatically enters cases of the tester and starts testing. When the vision tester 2 is used for monocular vision measurement, one eye needs to be shielded, and the other eye needs to be opened, the AI neural network algorithm can judge whether the left eye and the right eye of the tester are correctly shielded through the collected pictures, and if the shielding is wrong, the voice prompts that the left eye is shielded or the right eye is shielded are prompted. When the vision tester 2 is used for naked eye or glasses wearing vision measurement, the AI neural network algorithm can judge whether a tester wears frame glasses or not through the image transmitted by the image processing module 6, and if the glasses wearing state is inconsistent with the current test, the voice prompts 'please take off the glasses' or 'please wear the glasses'. When the vision tester 2 is used for vision measurement, a tester needs to feed back information of upward, downward, leftward, rightward, OK and unclear vision of the system, through an AI neural network algorithm, the tester only needs to make gestures or voices of up, down, left, right, OK and unclear vision, the intelligent module can automatically recognize the gestures of the tester and input the feedback information of the tester through gesture images transmitted from the image processing module 6, and a measurement report is given when the measurement is finished, or the intelligent module can automatically recognize the voices of the tester and input the feedback information of the tester through voice signals transmitted from a microphone connected to the image processing module 6, and a measurement report is given when the measurement is finished. The vision examination instrument combines the prior equipment, namely the vision examination instrument 1, the vision examination instrument 2 and the image processing module 6 together, and is matched with the functions of artificial intelligence recognition, voice interaction with a tester and the like, so that the vision examination has an objective and rapid reference, and meanwhile, the artificial intelligence, namely the addition of an AI neural network algorithm, makes the operation experience of the tester simpler and more comfortable.
