I think that the parameters in these models cannot be classified as distortion or intrinsic parameters as in traditional camera models. The parameters in the generic models simply specify the...

Could you run the program in gdb and print a backtrace for the crash to get some more information about where the program crashes? By the way, 3 images seem...

The reconstructions were first created in Colmap with a camera model that is supported by it. Then, additional bundle adjustment was applied to them by loading them in the camera...

To pin down the issue, it would be helpful to run the application in `gdb` and/or `valgrind` (while ensuring that it is built in either RelWithDebInfo or Debug mode). For...

Thanks for the gdb output. I had similar issues to this before when the compile flags between my application and OpenGV differed. I suspect that this might lead to a...

Okay, seems like the flag might not be the problem. But I believe that it is likely to be some inconsistency of that kind. For example, another possibility would be...

That is at least what I would try to check if I got these errors. All used library versions and compiler flags should be identical for compiling OpenGV and for...

1. The grid points are used with B-Spline interpolation to look up the viewing direction corresponding to a given image pixel (see our paper for an illustration). In order to...

I haven't implemented this. However, as long as a central model is used, it should not be difficult to undistort the images with the model in order to use them...

For an existing implementation of undistortion and stereo rectification, see for example: https://github.com/colmap/colmap/blob/dev/src/base/undistortion.cc
