Creating Orthoimagery

[smcmurray]

Hi I have a UAV dataset of about 2200 photos that I have got to the orthoimagery stage. I have managed to get a point cloud out and create a DEM no problems but when I go to generate the orthoimage it seems to get to the very end and then flash up :cannot write image . It seems that it cannot write the final orthoimage after it has calculated it ?? I have about 30gbs of drive space do that is not the problem - any ideas

Thanks in advance
Steve

it is cause of RAM space...

which version of photoscan you have?
I think with version 1.2.4 this problem is solved.

I am using version 1.2.4 and have 16gb of RAM in my machine - should I be using more to generate an orthoimage ?

Steve,

if you work with a smaller set / reduced bounding box, can you successfully generate your orthophoto?  and have you tried splitting the output image into blocks? (e.g. https://www.youtube.com/watch?v=vmGC_W9besQ)

Hello Steve,

During orthomosaic generation PhotoScan stores individually orthorectified images on the disk in the project files folder. Two thousands of images depending on the resolution may require more than 30 GB of disk space.
