LizardTech Awarded Lidar Patent for Point Cloud Compression

LizardTech, a provider of software solutions for managing and distributing geospatial content, has been awarded a USA patent for the compression of Lidar point clouds. The patented technology provides lossless compression of point clouds captured by airborne Lidar sensors or terrestrial laser scanners for easy and cost-effective processing, storage and transmission of data sets.

“LIDAR Systems捕获了由于处理此类大规模文件的困难而难以利用的数据，”John Hayes表示，Lizardtech高级工程师John Hayes表示。“我们的LIDAR压缩技术允许用户最大限度地提高他们对点云数据收集的投资回报。”

LizardTech developed the Lidar compression technology by leveraging the wavelet transformation algorithms used to compress satellite and aerial image data sets into MrSID formats. The point cloud compression technique was first released as a stand-alone LizardTech product called Lidar Compressor and then integrated into GeoExpress.

地理表格是最初创建的LizardTech的旗舰软件产品，以使地理空间专业人员能够操纵数字卫星/天线图像并将其压缩到行业标准MRSID或JPEG2000文件。LIDAR处理的添加给了GeoExpress将LIDAR数据的能力本身压缩到MRSID和LAZ格式，没有数据内容丢失，在处理文件中的存储和时间上可节省高达75％。

LIDAR压缩算法可以通过LizardTech SDK许可，将技术合并到第三方地理空间软件解决方案中。Lizardtech已经从想要在收集源放置数据压缩功能的硬件传感器开发人员中看到了对这项技术的兴趣。
