General / DEM problems at z value below sealevel

« on: August 16, 2017, 12:18:07 PM »

Hi everybody

I have a project where all targets and the object have minus z values (below sea level) because they are situated behind a dam in a bay of the sea. The DEM looks fine but obviously the software recognized the highest parts as lowest and vize versa. Exporting an orthophoto from that DEM does not work. Do you have any solution to that?

General / missing parts on orthophoto

« on: August 05, 2014, 05:21:30 PM »

Even though my models are complete in every detail, there are often parts missing on the orthophotos. These are usually parts of objects which have both an upper an a lower side / front and back side in the model. Has anybody a suggestion how I could export orthophotos which show all the details which are visible in the modell?

Thanks

General / calibrate underwater photo

« on: March 11, 2014, 12:49:30 PM »

Hi everybody
I have now been using Photoscan extensively on land without any camera calibration and great accuracy. We have also built some models of underwater structures which works very nicely. However measuring very accurately underwater is almost impossible and thus it is difficult to control the accuracy of these models. Has anybody experience with underwater photogrammetry and do you think that a camera calibration (eg. with a calibration sheet on site) is necessary or usefull?

Thanks!

Feature Requests / export of ortopicture of solid view

« on: November 30, 2012, 11:37:19 AM »

I would very much like to export ortopictures of the solid view of models - or lets put it like this, ortophoto without texture. Is it possible to pragram that? I think the solid view is very helpfull for making drawings over the pictures. It is certainly also much more suited for automatic tracing softwares.
Thanks!

General / ortopicture of solid view

« on: November 23, 2012, 11:35:28 AM »

I am working with the generation of architectural drawings over orthophotos. The solid view of a model is however often much better for understanding the surface. Is it possible to export an ortopicture of a model in solid view instead of the usual ortophoto of the textured view?
cheers
