QUESTION SIMULTANEOUS BUNDLE BLOCK ADJUSTMENT (SBBA) 1. Determine the number of Unkowns Quantities 3. Determine the number of Observed Quantities ANSWER Assumed That: 1. Forward Overlap is more than 50% 2. Side Overlap is more than 20% 3. Good minimum GCP distribution 4. Using the same camera 5. All Pass Point is same accuracy standards The Unknown Quantities 1. Rotational of Camera Axis There were 6 photos Each photos has 3 Quantities of rotational camera axis (Omega ω, Phi φ, Kappa, k) = 3 Quantities X 6 Photos = 18 Quantities 2. Coordinate of Exposure Stations There were 6 Exposure Stations at 6 Photos. Each photos has 3 Quantities of Exposure Station Coordinates (x o , y o , z o ) = 3 Quantities X 6 Photos = 18 Quantities 3. Photo Coordinates of Ground Control Point (GCP) There were 4 GCPs. (A, B, C, D) Each GCPs Coordinates have 2 Quantities (Xg, Yg) = 2 Quantities X 4 GCPs = 8 Quantities 4. Ground Coordinates of Pass Points There were 15 Pass Point. Each Pass Point Coordinate has 3 Quantities (x, y, z) = 3 Quantities X 15 pass Points = 45 Quantities Total Unknown Quantities = 18 + 18 + 8 + 45 = 89 Quantities
