stereocamb (a1)
STEREOCAM consists of three pairs of stereo camera setups that aim to provide synchronized and stereo-calibrated time series of images that can be used for 3D cloud mask reconstruction. Each camera pair is positioned at approximately 120 degrees from the other pair, with a 17°-19° pitch angle from the ground, and at 5-6 km distance from the ARM Southern Great Plains observatory to cover the region from northeast, northwest, and southern views. Images from both cameras of the same stereo setup can be paired together to obtain 3D reconstruction by triangulation. 3D reconstructions from the ring of three stereo pairs can be combined together to generate a 3D mask from surrounding views. A pair of ARM cloud digital cameras is being used for mobile deployments.
Point Cloud of Cloud Points PCCP from CACTI Stereo Cameras
The Point Cloud of Cloud Points (PCCP) data set is composed of 3D coordinates describing the position of cloud features and images from which these coordinates are reconstructed. Images are captured in the daytime by two ARM cloud digital cameras (ACDCs) at CACTI S4a and S4b sites, at 20-second intervals. The two cameras are located at 32.1274oS,64.7139oW, and 32.1185oS, 64.7237oW. The 3D positions are detected with respect to the AMF base location at 32.1264oS, 64.7284oW, and 1141 m above sea level. The PCCP data format is the same as explained in PCCP VAP Technical Report.
