Point Cloud Compression

Point clouds are enormous datasets describing 3D points with associated data such as distance, color, and other attributes. Tencent Media Lab developed an industry-leading algorithm for high-quality real-time compression of point cloud data to greatly reduce storage and transmission costs

  • Industry Standards

    Tencent Media Lab is a member of the industry standards organizations to develop domestic and international point cloud compression standards. The Media Lab not only participated in the creation of the standard but has also adopted and implemented the standard into actual projects.

  • Industry-Leading Compression

    Scene-adapting compression algorithm achieves high efficiency and high-quality compression of point cloud data to significantly reduce storage and bandwidth costs.

  • Real-Time Encoder

    Media Lab internally developed a fast point cloud codec with a fully optimized compression algorithm to ensure real-time high-quality data compression and transmission.

  • Secure and Reliable

    To ensure the security and privacy of the data transmission, the compressed point cloud data will be purged immediately after delivery for a secure and reliable production process.
