What Drives DPW Development?
New sensors – aerial cameras, lidars, satellites, gps-imu, … Computer technology New Algorithms Network technologies User experience and wishes
New sensors Satellite imagery: Higher productivity, large blocks Aerial survey: high overlap, big color depth (>8 bits per channel), special oblique cameras, lidars
Computer technologies 64-bit computing Multicore CPU multithreading Clusters CUDA, MIC,… Operating system – Windows 7 Home Premium 64 Processor Cache] - 3 rd Generation Intel (R) Core (TM) i5 3330 quad-core processor [3.0GHz, 6MB Shared Memory – 6GB DDR3-1333MHz SDRAM [2 DIMMs]
New algorithms Computer Vision –> algorithms Pattern recognition –> automation 3D
3D geoportals, 3D GIS … Do we need 3D point clouds?
3D Automatic 3D points conversion to vector objects: roofs, roads, …
