Abstract:

Aiming at the problems of low matching precision and complex calculation of traditional 3D scene surface reconstruction feature points, a new algorithm based on virtual reality technology is proposed. The image texture information is processed by wavelet decomposition, the image is encoded quantitatively and the distance between the visual points and images is taken as the measurement value. The appropriate critical value is selected to complete image compression and the redundant data of 3D scene image is eliminated. The heuristic information in the image is calculated, the pheromone matrix is updated, the critical value of the pheromone matrix is used to determine whether the pixel point is the edge point of the image, and the edge information of the 3D scene image is extracted. The minimum recognition distance of 3D scene is calculated by virtual reality equipment, and the deviation between theoretical image projection value and actual projection value is calculated. The pixel value of image surface reconstruction is calibrated by deviation value, and the surface reconstruction target of high precision 3D scene image is completed. The simulation results show that the proposed method can capture the key features of 3D scene image effectively, and the resolution of reconstructed image is improved significantly.
