RPBA

Robust Parallel Bundle Adjustment

For compilation use CMake

RPBA is controled via the file "parameters"

• Robust: 1 means that robust estimation is used
• Exteval: 1 means that back projection error is computed, but no adjustment
• Threads: Number threads - 0 means physically available number
• k2: 1 means that second order radial distortion is estimated
• k4: 1 means that fourth order radial distortion is estimated
• f: 1 means that focale length / camera constant is estimated
• k24out: 1 means that the output of PBA can be read
• InputDir: Name of input directory
• File: File name with format

RPBA uses the data format defined in the project "Bundle Adjustment in the Large"

https://grail.cs.washington.edu/projects/bal/

and has been particularly tested with

• problem-961-187103-pre.txt

and the largest blocks

• problem-3068-310854-pre.txt
• problem-4585-1324582-pre.txt
• problem-13682-4456117-pre.txt
