Example Embodiment

[0040] The technical scheme of the present invention will be further described in detail below in conjunction with the accompanying drawings:

[0041] Such as figure 1 Shown is a schematic diagram of the system composition of the present invention, including three parts: establishing the model of the eyeball optical axis, binocular visual axis, and the relative spatial relationship between the head and eyes, three-dimensional eye movement feature extraction, and recognition of eye movement feature parameters.

[0042] The double sphere model can infer the optical axis from the three-dimensional eyeball data, and combine the matching of facial feature points to obtain the relative relationship between the binocular visual axis and the head and eyes; the three-dimensional eye movement feature extraction means that after three-dimensional modeling, three New eye movement parameters; intelligent recognition of developmental disorders in infants and young children refers to the applicati...

Abstract

The invention discloses an infant growth obstacle intelligent evaluation method based on a three-dimensional eye movement characteristic. The method mainly comprises the three steps of establishing adouble-sphere model of an eyeball optical axis, a binocular vision axis and a head-eye relative space relation, extracting the three-dimensional eye movement characteristic, and performing intelligentidentification of the infant growth obstacle. The double-sphere model estimates the optical axis according to the three-dimensional eyeball data, and obtains the relative relation between the binocular vision axis and eyes on the head. In three-dimensional eye movement characteristic extraction, a new eye movement parameter is obtained after three-dimensional modeling. In intelligent identification of the infant growth obstacle, an algorithm is applied for performing intelligent cleaning, storage, analysis, mining and displaying on mass eye movement data, and an association between a typicalparameter and a specific growth function obstacle is obtained, thereby determining the type of the obstacle. The method overcomes restriction in obtaining the eye movement characteristic; data miningtechnology and artificial intelligence technology are applied, thereby supplying a new technical tool for more objectively and comprehensively evaluating development of the infant cognition capability.

Description

technical field [0001] The invention relates to the field of infant development assessment, in particular to an intelligent assessment method for infant developmental disabilities based on three-dimensional eye movement features. Background technique [0002] Research on the plasticity mechanism of visual development and eye movement control mechanism has always been a hot spot in pediatric ophthalmology research. However, with the development of visual development science, its clinical application has increasingly extended and crossed from ophthalmology (eye diseases, strabismus and amblyopia) to developmental pediatrics. Vision is the main channel for human beings to obtain information, and it plays an important role in integrating other sensory tasks. Because the language and movements of infants are not yet fully mature, vision becomes one of the important ways to understand the level of brain development and cognitive development of infants before they can fully expres...
