Data Compression Method for Road 3D Scene Real-Time Network Transmission

Abstract:

In view of the contradiction between massive data of road 3D scene and bandwidth of current network transmission, a data real-time compression method for massive 3D road scene is proposed. Firstly, three-dimensional coordinates are reduced to two-dimensional by localization. The bit rate is also significantly reduced by relative treatment. Secondly, the inter-frame prediction method applicable to road scene rendering is proposed in order to reduce data redundancy of adjacent stations. Thirdly, a lossless and high compact data format is defined to store the coordinates for road scene network transmission. Finally, the bit stream is further compressed by using adaptive arithmetic coding and thus higher compression ratio is obtained. Applications show that this compression method meets the requirements of road scene real-time network transmission.
