Texture Generation Method of Three‑Dimensional Model of Crime Scene Based On Multi Panoramic Images
To solve the problems of considerable data volume and poor rendering effect in the traditional vertex shading rendering method of three-dimensional (3D) mesh, this study proposes a method to generate clear texture images using the fusion technology of point cloud and multiple-station panoramic images. First, the occlusion from the spatial mapping point of the panoramic texture pixel to the center of the panoramic sphere was calculated. Subsequently, the spatial color domain inverse distance weighted fusion of multiple-station panorama was conducted under texture image pixel point visibility. Additionally, the texture image blank area neighborhood weighted filling was conducted to generate a clear texture image. Finally, panoramic images and laser point clouds were collected as data sources to generate texture images. The experimental results show that the algorithm designed in parallel can quickly generate highly clear textures from multiple-station panoramic images. The overall effect of the model is more realistic and clearer than vertex colored model. The visualization effect of the 3D model of a crime scene is also improved.
