New learning-based method enhances LiDAR point cloud compression

By PulseAugur Editorial · [1 sources] ·

Researchers have developed Inter-LPCM, a novel learning-based method for compressing LiDAR point cloud data. This approach improves upon existing techniques by utilizing inter-frame prediction to capture complex motion and structural dependencies, which traditional linear models struggle with. The method incorporates specialized models for predicting radius and elevation angles, along with optimized quantization and distinct entropy coding for each spherical coordinate component to enhance compression efficiency.

    Inter-LPCM: Learning-based Inter-Frame Predictive Coding for LiDAR Point Cloud Compression

    Because LiDAR sensors acquire point clouds with a fixed angular resolution, the resulting data can be systematically parameterized and efficiently compressed in the spherical coordinate system. Traditional spherical coordinate-based point cloud compression methods have demonstrat…
