Pix4D doesnt model dataset of broadcast tower and models terrain instead

Pix4D Café

Hi Guys,

A short while ago we planned on producing a 3d model of a 320m high broadcasting tower. I have completed 3D terrain models in the past with success but when we tried to process the tower as a model it failed to stitch the tower and modelled the terrain instead. Is the error from the image capture (linked below) or a process within Pix4D that I am failing to grasp?

Here is a link to the data set from one face. For the model we used the data from all 3 faces. https://drive.google.com/drive/folders/13LRhndn7NDMh9w8VDO8cyTuUDzoPTAxX?usp=sharing

Hello Matthew,

I recommend using Pix4Dscan and Pix4Dinspect that are dedicated to this type of application.

Im not sure how you got anything to stick with all the sky in the background? your camera should be tilted down at about 45 degrees so you don’t get any sky in the image.

I would try an odd number of orbits raising elevation 15 ft or so every rotation.

Good luck
