LARGE GAPS IN THE DATA PROCESSED USING VISUAL SFM

LARGE GAPS IN THE DATA PROCESSED USING VISUAL SFM

I am doing a research project titled “Genearation High resolution DSM using UAV images” for my final year of Engineering Study.
Under this project i am testing follwoing four software’s capability to process UAV images.
1.LPS 2011(Erdas Imagine)
2.Agisoft Scan Pro
3.PIX4D
3.VisualSFM
All the software i mentioned except VisualSFM are commercial software and i am using trial license for them.While working with VisualSFM i am having problm with
the output.he outpcome of dense point generation isnt satisfactory. Gaps/holes exist in many places .I am afriad how this culd happen when such robust algorithm
is being used for tie points generation.The data I am using consits of 25 images of an area inside a campus and exterior orientation parameters for all images have
been provided.I guess the low quality of data from GPS/INS sensor mounted on UAV i.e the exterior orinetation has resulted to such output.Please provide me the what can be the best soultion in
this scenario where there are no GCPS and the exterior orientation parameters are also not much accurate.

    Hey, did you manage to finish this project. I am currently doing a comparison between commercial and open source SFM software and I would be interested if you got similar results to me.
