Study on Construction of Three-Dimensional Interaction Virtual Reality of Corridor Based on Computer Vision

The current methods of construct three-dimensional interaction virtual reality include Photogrammetry, Point Cloud Modeling and Building Information Modeling. However, due to the limitation of space size, these methods cannot construct three-dimensional interaction virtual reality modeling effectively, like corridor. In this paper, the method is proposed to construct corridor three-dimensional interaction virtual reality. The method based on computer vision includes data acquisition, texture stitch, path selection, and model construction. In the process of acquiring data, firstly, we obtain the perspective transformation parameters by pre-establishing the check field. Secondly, we correct the acquired data in real-time by using perspective transformation. In the process of stitching texture, according to the number of feature points in the images, we use feature/direct stitch to generate texture. In the process of selecting path, we identify the targets in image and build buffers. The absolute error and root mean square error are used to measure the accuracy of corridor three-dimensional interaction virtual reality. The experimental result shows that the absolute error of the model constructed in this paper is about 0.0507 to 0.1691. And the root mean square error is about 0.1203 to 0.1318.
