hi,

i do some more tests.
i post the results inside my issue in github.
https://github.com/OpenDroneMap/OpenDroneMap/issues/119
i think the problem happens in geo referencing process.
after creation of the odm_textured_model_geo.obj the area calculation is totally wrong.
in my example the area of the odm_textured_model.obj is 116.141m2. this is also wrong but
after geo referencing the area of odm_textured_model_geo.obj is 4.48494e-06m2. means
0,0000045m2. the orignal area is ~13000m2. if odm_orthphoto should use 20px / meter
default value the result must an image with only one pixel.

to validate this i create an orthphoto like this:
odm_orthophoto -inputFile reconstruction-with-image-size-2400-results/odm_texturing/odm_textured_model_geo.obj -logFile odm_orthophoto_log.txt -outputFile odm_orthphoto.png -resolution 1000000.0 

if i set -resolution to 1000000.0 the resulting orthfoto size is 2120x2117 px.

here is the beginning of the corresponding log file:
