Turing model-based augment reality assembly environment system modeling method

Abstract

The invention relates to a Turing model-based augment reality assembly environment system hierarchical colored petri nets (HCPN) modeling method. By taking a Turing with a model of calculating 'X+1' for reference, the Turing can record the current state X, acquires an up-to-date command after input is given, provides the up-to-date state output, and applies the state output to establishment of a hierarchical colored Petri net model to ensure that the model can remember the current internal state and combines the input to make correct judgment of the state at the next moment. Colored petri nets (CPN) Tools are adopted to establish a model of the augment reality assembly environment system, wherein a network is layered; and a virtual hand sub-network, an event management sub-network, an assembly sub-network and the like are refined, input and output of each sub-network are utilized to realize event driving, and the relations among various factors in the network are determined, so that the augment reality assembly environment system has logical inference property, can effectively process massive random discrete events, is convenient to express the dynamic establishing process of the assembly model, and has the capability of sensing the user intention.

Description

technical field [0001] The invention applies the Turing machine model to the hierarchical coloring Petri net, and models the augmented reality assembly environment system. The method can realize an event-driven assembly process and respond to user operation intentions, and is used for modeling of an augmented reality assembly environment system, belonging to the field of augmented reality application technology. Background technique [0002] In the augmented reality assembly environment system, video cameras are generally used to capture real assembly scene images, which are synthesized with computer-generated virtual objects through various registration algorithms, and finally displayed on the head-mounted display. The augmented reality assembly environment enables engineers to operate virtual parts while operating real parts, and it can help users understand various assembly relationships in the scene with the help of virtual-real mixed augmented assembly prototypes.

Problems solved by technology

At present, in the existing assembly simulation systems, most of the scene graphs are used to construct and describe the scene. After continuous improvement, the scene graph can well represent the object's orientation information, 3D geometric information, material and lighting attribute information, and can be added by adding The information contained in the scene graph meets the requirements of assembly simulation to a certain extent, but it cannot handle random events in the assembly operation and realize the user's operation intention; foreign scholars use the helmet display and data gloves to establish a human-computer interaction augmented reality assembly The system, which can explain the user's intention, can meet the requirements of augmented reality assembly, but cannot express the dynamic building process of the assembly model and reduces the efficiency
