Key Point Detection Method of 3D Network Model Based on Virtual Reality Technology

In order to meet the higher requirements of today’s society for details and fidelity 3D models, a key point detection method network models based on virtual reality technology is proposed. The technical steps include model normalization preprocessing, feature extraction, similarity calculation. retrieval test cars, trucks, buses carried out using VTFT algorithm. results showed that in different databases, highest success rate was 86.4% lowest 77.10%. Practice has proved this can effectively improve efficiency accuracy current processing better social needs such as games entertainment.
