Abstract

The invention discloses a virtual-real fusion simulation experiment error auxiliary method and system. The method includes: in an experiment process, performing video acquisition on the operation steps of the experiment to obtain an operation experiment video; graying the corresponding image data of the operation experiment video and the standard experiment video, carrying out edge identificationto extract a contour line, constructing an Euclidean distance matrix of feature points through the feature points for matching, and if the matching is unsuccessful, sending out an experiment misoperation prompt and a correct contrast image. In the process of carrying out the experiment steps, the correctness of each step is detected and recorded in real time, and prompting is carried out on each wrong node; when the operation error of the student is large and exceeds the allowable error range, the student is prompted that the step is wrong in the virtual environment, and the correct operationstep of the current step is given to the student for watching, so that the learning efficiency and experiment efficiency of the virtual experiment are improved.

Description

technical field [0001] The present disclosure relates to the technical field of virtual experiments and video image processing, and in particular to a method and system for assisting errors in virtual-real fusion simulation experiments. Background technique [0002] Virtual reality (VR) is an experience that takes place in a computer-generated reality, where the immersive environment can resemble the real world or be completely different from it. Applications of virtual reality can include entertainment (ie gaming) and educational purposes (ie medical or military training). [0003] Currently, standard VR systems use VR headsets or multi-projection environments to generate realistic images, sounds, and other sensations to simulate the user's physical presence in the virtual environment. A person using a virtual reality device is able to look around an artificial world, move around it, and interact with virtual features or items. The effect is usually produced by a virtual ...
