Workflow from Pix4D to Stereo-Photogrammetry

We had the task to deliver besides a DTM a “classical” Map. For us the best way to retireve this “Map-Data” is by Stereo-Restituition which is the classical Photogrammtery approach. The Tool whe found which works seamless togehter with Pix4D is StereoCAD from Menci. You just choose the Pix4D project file as input data and StereoCad compiles automatically the Stereomodels. After that compilation you can look to your Object in 3D with glasses(anaglyph or shutter) on your screen (looks phantastic!!!) and draw the MapData in 3D. Very nice and easy to handle tool.

Hi Ulrich,

Thank you for sharing your experience with us!

Please also note, that Pix4Dmapper has drawing tools such as:

Polylines: https://support.pix4d.com/hc/en-us/articles/202560309

Areas/Surfaces: https://support.pix4d.com/hc/en-us/articles/202560269

 

We do not use Stereo technology but we have the rayCloud that could replace the stereo-viewing:

In case that stereo-viewing is necessary, Pix4Dmapper exports very accurate camera parameters (internal and external) and undistorted images that can be used by other traditional photogrammetric software.

Best regards,

 

 

Hi,

Although no doubt that Multi-Ray approach in Ray-Cloud has the highest possible accuracy

But using Ray-Cloud to vectorize and extract features is extremely time consuming ,

snap to the dense cloud, check and correct in several images is simply unaffordable in terms

of required time for operators, comparing fast drawings in Stereo-Mode in traditional software packages

What could be an optimum solution to have both advantages?

Clicking the original images gives you a way to be more precise for the creation of the point, but it is also possible to simply click the point cloud when digitizing features.
