ETH3D Camera Model Implementations
This repository contains implementations of the camera model used in the ETH3D benchmark.
- The "cpp" folder contains a C++ implementation without any dependencies.
- The "cpp-cuda" folder contains a C++ implementation which is CUDA-compatible, i.e., it requires CUDA to compile and can be used within CUDA code (but also within CPU code).
- The "matlab-octave" folder contains a small script which can be used to compute derivatives with MatLab or octave.
Please notice: The C++ implementations assume a different pixel coordinate convention than the camera calibrations provided by the benchmark. The calibration format used by the benchmark assumes (0, 0) in pixel coordinates to be the top-left corner of the top-left pixel, while the camera model implementations assume (0, 0) to be the center of the top-left pixel. The calibrations given by the benchmark can be easily converted to the other format by subtracting 0.5 from cx and cy.
