Embodiment Construction

[0075] In order to better understand the present invention, some basic concepts are firstly explained.

[0076]Weighted graph: A set pair (V, E) consisting of a set of points V and a set E of connections between points is called a graph, represented by G(V, E). The elements in V are called nodes and the elements in E are called edges. A graph whose node set V and edge set E are both finite is called a finite graph. If any side (i, j) in the graph is assigned a number ω(i, j), this number is called the weight of the side. A graph that is assigned weights is called a weighted graph. After assigning weights to each edge of the directed graph, it becomes a directed weighted graph.

[0077] EM algorithm: It is used in statistics to find the maximum likelihood estimation of parameters in a probability model that depends on unobservable hidden variables. The EM algorithm is also called the maximum expectation algorithm. The Expectation Maximum (EM) algorithm is an algorithm for ...

Abstract

The invention discloses a children cognitive system based on augment reality technology and a cognitive method. The children cognitive system based on the augment reality technology comprises an image information input module, an image information matching module, a drawing model module and a voice recognition module. A set of recognition identifications are developed through interfaces of an ARToolkit augment reality development kit, a Microsoft Speech SDK voice recognition engine, a 3D max modeling tool and the like, and a children cognitive platform performs simple interaction with a virtual scene in a computer through voice recognition. Operations like moving, amplifying and contracting a model are achieved through OpenGL image processing technology and 3D modeling technology. The children cognitive system based on augment reality technology and the cognitive method have the advantages of being short in development cycle, good in maintenance, good in portability and easy to modify. In addition, a user can use the cognitive system based on augment reality technology and the cognitive method to write a literary handbook, good learning effect is achieved, and the cognitive platform which is strong in interaction is provided for a child to use an augment reality application system.

Description

technical field [0001] The invention relates to a children's cognitive system and cognitive method based on augmented reality technology, belonging to the field of augmented reality technology. Background technique [0002] Augmented reality is to combine computer-generated virtual objects with the real world to construct a virtual space combining virtual and real. The information provided by the computer system is used to enhance the user's perception of the real world. It can enhance or capture what the human eye sees, and superimpose the computer-generated virtual objects, scenes or information prompted by the system on the real scene, so as to realize "augments" to the real world. Augmented reality technology has a wide range of application scenarios in the fields of industrial design, machinery manufacturing, construction, education, and entertainment. It not only provides an easy-to-implement virtual reality method, but also represents the next generation of easier-to...
