Create a Kinect 3D point Cloud with Openni

This is also a continuation of the previous article, "through the Opneni combined Kinect depth and color image information." The depth of the Kinect can be read through Openni, after the color information, you can actually try to use this information to reconstruct the 3D environment to show that, in fact, the depth information that was read in the previous example is raw, and the coordinates are also the coordinates of the sensor's two-dimensional im

CALIPSO quality statements Lidar Level 2 Cloud and aerosol Layer products

Introduction Cloud and aerosol Layer products document the spatial location of major geophysical variables, the surrounding meteorological conditions (such as temperature and pressure), and some of the optical properties of measurements and derivations. The optical properties of the direct measurement include the integral decay backward scattering, the volumetric offset ratio, and the attenuation of the total color ratio. The derived optical properti
