The Design And Realization Of Corn Cultivation Knowledge Visualization System Based On Somatosensory Interaction

With the combination of knowledge visualization technology and agricultural production knowledge becoming more and more close and important,the visualization of agricultural knowledge which has been applied in the field of agriculture has become the focus of research.Knowledge visualization is the technique of constructing and expressing the complex knowledge in a certain field by using graphic image,three-dimensional model,video animation and so on,which provides an innovative way to deal with the obscure and dull knowledge.Secondly,the current interactive means of the visualization of agricultural knowledge can not meet the growing needs of people,Because of the rapid development of human-computer interaction technology,the body-sensing interaction technology has become a new field of natural interaction research,in which gesture recognition is the focus,and the body-sense interaction technology can make up the problem of the lack of interaction,which is of great significance to improve the interactivity of agricultural knowledge visualization.Based on the research of corn cultivation knowledge,the paper designs and realizes the visualization system of maize cultivation knowledge by means of knowledge visual representation.Through the visualization system of maize cultivation knowledge,we can make people study and master the knowledge of corn cultivation,and improve the spread and popularization efficiency of cultivation knowledge.The interaction between the visual system of maize cultivation knowledge and with the problems of low immersion,cumbersome operation and poor experience,the interactive content of the system is used as the object of the research,and the method of gesture recognition is used to complete the body sense interaction,and the body sense interaction is integrated with the visual system of corn cultivation knowledge.A visualization system of maize cultivation based on somatosensory interaction was constructed.The main contents and results of this paper are as follows:1.To design the visual system of maize cultivation knowledge,the paper firstly maps the knowledge objects in the virtual space to the knowledge and technology of maize cultivation,and then according to the knowledge of maize cultivation,the six scenes in the process of maize cultivation are designed,and the model construction and The visual scene of corn cultivation was constructed by script processing and scene rendering.2.In order to increase the human-computer interaction function based on the body sense in the system,six kinds of static gestures and five kinds of dynamic gestures are designed.Using the threshold method,the dynamic and static gesture classification of Kinect captured gesture data is carried out.Based on the pretreatment of static gesture image,the recognition of static gesture is realized by HOG feature extraction and Bayesian regularization BP neural network,and the results are as follows: The average recognition rate of hog+ Bayesian regularization BP neural network is 91.3%,HOG+SVM average recognition rate is 87%,It shows that the recognition algorithm adopted in this paper has better recognition effect;Based on the feature extraction of dynamic gesture motion trajectory,the DTW algorithm is used to realize the dynamic gesture recognition,through the experiment result: the average recognition rate of the dynamic gesture is 90.8%,which indicates that the recognition method is effective and the recognition rate is high.3.Based on the integrated design,the interactive object of maize cultivation knowledge visualization system is added script,the function interface and data in the dynamic link library are called through script,and the object of the visual interaction is realized,and the integration of the visual system of maize cultivation knowledge and the body sense interaction is achieved.A visualization system of maize cultivation based on somatosensory interaction was constructed.In this paper,through the design of the visual system of maize cultivation knowledge and the design of body sense interaction based on gesture recognition,by integrating the two,a visualization system of maize cultivation knowledge based on the interaction of body is constructed,which realizes the interest of crop corn cultivation knowledge and technology,and enhances the interaction of crop visualization system,It has important application value to spread and popularize agricultural knowledge and technology.
