Tetra

Photo Positioning Algorithm

Alternatives

• Collinearity Equation "Matrix-Based".
• DLT "Matrix-Base".

Why Tetra?

• Fast, Tetra is a derivative-free "Search-Based" algorithm.
• Work with a minimum number of Known Points: 3 Known Points result in a max of 4 solutions, 4 Known Points give a unique-solution.
• No calibration info was needed for it to work.
