Embodiment 1

[0030] figure 1 It is a flow chart of a visual test scoring method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of scoring visual tests. The method can be executed by a visual test scoring device, and the device consists implemented in software and / or hardware, and can generally be integrated into scoring devices for vision tests. Scoring equipment for visual tests includes, but is not limited to, computers. like figure 1 As shown, it specifically includes the following steps:

[0031] Step 101, acquiring the test paper photo of the visual test test paper submitted by the user.

[0032] Among them, the user performs image recognition and image drawing according to the visual test paper. The user's visual discrimination and visual memory are investigated through the visual test items on the visual test paper. The visual test paper includes header area, footer area, test box area, standard pattern template area and user a...

Embodiment 2

[0046] figure 2 It is a flow chart of a visual test scoring method provided by Embodiment 2 of the present invention. This embodiment optimizes step 102 on the basis of the above-mentioned embodiments: determine the image of the answer part in the photo of the test paper, and the image of the part of the answer The corresponding question number includes: marking the image coordinates of the preset recognition area on the test paper. The preset recognition area includes the header area, footer area, test frame area, standard pattern template area and user answer area, where the standard pattern template The area and the user answer area are located in the test frame area; the scale-invariant feature transformation feature points of the header area and footer area are determined by the scale-invariant feature transformation algorithm; the standard pattern template area is determined by the direction gradient histogram feature extraction algorithm The directional gradient histog...

Embodiment 3

[0072] image 3 It is a flow chart of a visual test scoring method provided by Embodiment 3 of the present invention. This embodiment optimizes step 102 on the basis of the above-mentioned embodiments: determine the image of the answer part in the photo of the test paper, and the image of the part of the answer The corresponding question number, including: obtaining the photo of the test paper; determining the photo of the test paper as the pre-stored standard test paper; Question number. like image 3 As shown, the method includes:

[0073] Step 301 , acquiring the test paper photo of the visual test test paper submitted by the user.

[0074] Step 302, obtaining the photo of the test paper.

[0075] Wherein, the photographing device photographs the test paper to generate a photo of the test paper. Get a photo of the test paper. Optionally, the photo of the test paper generated by the shooting device is acquired through wireless transmission or wired transmission.

Abstract

The embodiments of the invention disclose a grading method for a visual test, a grading device for a visual test, an apparatus and a storage medium. The method includes the following steps that: the test paper photo of a visual test paper submitted by a user is obtained; an answer part image in the test paper photo and question numbers corresponding to the answer part image are determined; and a test topological structure corresponding to the answer part image is determined according to the answer part image and the question numbers corresponding to the answer part image; and the test topological structure is compared with a corresponding standard topological structure, and a grading result corresponding to the answer part image is determined. With the grading method for the visual test, the grading device for the visual test, the apparatus and the storage medium provided by the embodiments of the invention, visual test grading can be automatically performed according to the visual test paper submitted by the user, manual intervention can be reduced, manual data analysis processes in visual ability test evaluation can be decreased, and the accuracy of the visual ability test evaluation can be improved.

Description

technical field [0001] Embodiments of the present invention relate to visual ability evaluation technology, and in particular, to a scoring method, device, equipment and storage medium for a visual test. Background technique [0002] Visual ability is closely related to the development of children's cognitive ability. In the process of children's development, consciously providing them with color, shape and other visual stimuli will not only help the development of their visual ability, but also improve their cognitive ability . During the teaching process, by obtaining the evaluation results of children's visual ability, teachers can clearly understand the development stage of children's visual ability and the problems they are facing, so that teaching can be ahead of children's development and guide them, so as to provide for children's development. An important foundation is laid for the development of visual abilities. [0003] In the prior art, the ophthalmologist gen...
