Virtual reality technology first appeared in the 1980s and can also be called VR technology, which contains computer technology, sensing technology, human interaction technology, and artificial intelligence technology. With the continuous maturation of virtual technology, which is now one of the world’s frontier scientific projects, large site scene interaction processing there are different transformation scales, transformation scale occurs, its existence of numerical differences, resulting in the output of the scene image produces missing, for the problem, this paper uses virtual reality technology of animation interactivity design integrity automation analysis method. The process uses virtual reality technology to output interaction instructions, determine the angle of change generated by the interaction change instructions, use bilinear difference processing to reconstruct the vector value space formed by the interaction semantics, iteratively back-project the interaction image and form a correction parameter within the output image range values, control the numerical difference generated during the transformation, sample the feature vector obtained by contour screening, and superimpose the interaction deformation within the propagation field values in the propagation field to achieve integrity analysis. This study builds a large site scene interaction platform, iterates the virtual reality editing framework, applies the analysis method based on visual scene understanding, the analysis method based on the immersion model and the designed automated analysis method to participate in the test, and the test results show that the output of the designed automated analysis method does not produce missing animated images, the integrity analysis results are the best and the designed integrity analysis method produces the average analysis time generated by the designed integrity analysis method is 8s, which largely reduces the working time and improves the efficiency. Through the VR market research statistical chart, the analysis shows that both online and offline VR market shows a linear increase from 2017 to 2021, further indicating that virtual reality technology will have a broad application prospect in the future and produce a disruptive change in the way human society interacts with each other.
