General / Registration of scan data with UAV

« on: January 06, 2015, 02:22:09 PM »

We have scanned as well as imaged an object. I want to register scan and image data together.
At the moment we are using just natural features as tie points between two data sets.
But for higher accuracy, I'm planning to use targets. What sort of targets should I take. Also
shape, size etc.
Flying height: 20-30 m.
Any suggestion??

General / Quality measurement of point cloud

« on: January 06, 2015, 02:21:12 PM »

I just wonder if there is some quality measures of the dense point cloud generated by images in photoscan.
How can I know the quality of single point in dense cloud.

If my images are max at 10 m and I 'm using middle, high, ultra high setting for dense cloud, what approximately pixel accuracy should I have.

General / Setting position of images manually

« on: January 06, 2015, 02:19:05 PM »

I have downloaded latest version of Photoscan (1.1.0.2004).
I wanted to give x,y,z coordinates of my images  but I' cann't do it.
There is no ground control button now.
Instead there is reference button which doesn't allow to give x,y,z of the images.

In last version (1.0.2.1824), there was ground control and there by clicking on image you could give x,y,z of the images.
