Then it should work with OTB as well … Can you file a bug report ? And post the
result of the ReadImageInfo app on the inputs, it helps to understand how otb
sees your data.

image
Hi,
They overlap correctly and yes you are right the input images already have a
projection. I tried gdal_pansharpen and it has generated a valid image, I am a
bit lost here!

Hi,
it looks like your output image is empty (filled with 0). It also looks like
your input images already have a projection, when you open them in QGIS do they
overlap correctly ?
For clarity, you should also specify the file extension of output image :
pansharpened_image.tif

Hi,
What file format are you using for input and outputs ? Can gdal read the
inputs/output with gdalinfo ?

Objet : [otb-users] otbcli_BundleToPerfectSensor is generating an invalid image
Hi,
I am using otbcli_BundleToPerfectSensor to pan-sharpen a worldview3 image. It
is generating an image which seems to be invalid, when I try to load the image
on QGIS I get std::bad_alloc. I have ubuntu 14.04 server where I installed
otb-bin 5.4.0+dfsg-1~trusty2 and used the following command to generate the
image:
otbcli_BundleToPerfectSensor -ram 4096 -inp input_pan_image -inxs
input_multispectral_image -out pansharpened_image uint16
Am I missing something? Any help will be appreciated.
