# mrcal-from-cahvor(1)

Converts a .cahvor-formatted camera model to the .cameramodel file format

## NAME

mrcal-from-cahvor - Converts a .cahvor-formatted camera model to the .cameramodel file format

## SYNOPSIS

```
  $ mrcal-from-cahvor model1.cahvor model2.cahvor
  Wrote model1.cameramodel
  Wrote model2.cameramodel
```

## DESCRIPTION

File formats supported by mrcal are described at \<http://mrcal.secretsauce.net/cameramodels.html#cameramodel-file-formats\>

This tool converts the given model(s) to the cameramodel file format. No changes to the content are made; this is purely a format converter (the mrcal-convert-lensmodel tool fits different lens models instead). Model filenames are given on the commandline. Output is written to the same directory, with the same filename, but with a .cameramodel extension.

If the model is omitted or given as "-", the input is read from standard input, and the output is written to standard output

## OPTIONS

### OPTIONAL ARGUMENTS

  --force, -f      By default existing files are not overwritten. Pass --force
                   to overwrite them without complaint
  --outdir OUTDIR  Directory to write the output models into. If omitted, we
                   write the output models to the same directory as the input
