I am not sure what the file format of your imagery is but it is likely that GDAL will have a driver that is able to handle it. You can check against the list of supported raster file formats at http://www.gdal.org/formats_list.html. In R you would use either the raster() function in the raster package, or the readGDAL function in the rgdal package to open your image via GDAL.
It is a bit more complicated to do so in Python. You can interface with Python's GDAL module directly or you may be able to open your image slightly more indirectly using the RIOS module (http://rios-test.readthedocs.io/en/latest/; I haven't used it myself).
