Photogrammetry
Photo ● gram ● metry
φωτός (photós) = light
γράμμα (grámma) = drawing
μετϱικὴ (metriké) = measurement
History
Almost as old as photography (François Arago 1839)
Mathematical foundation in 1849(Aimé Laussedat)
First full algorithm in 1899(Sebastian Finsterwalder)
What’s new?
Computer vision for feature detection
Compute Bundle Adjustments fast
Compute Depthmaps fast
CUDA
SIFTGPU(Feature detection)
Multicore Bundle Adjustment(Bundle Adjustments)
RealityCapture(Depth Reconstruction)
7.000.000.000.000FLOPS (SP Peak) with a Quadro M6000
(that is over 9000!)
Getting more popular in Realtime 3D
