hello alexey
thanks for your reply
here is the two cunks and the merge
PhotoScan.app.document.chunk.dense_cloud.meta
Out[2]: 2017-04-27 10:18:04 {'dense_cloud/density': '100', 'dense_cloud/depth_downscale': '2', 'dense_cloud/depth_filter_mode': '2', 'dense_cloud/duration': '15728.681', 'dense_cloud/resolution': '0.00200377260553607'}
PhotoScan.app.document.chunk.dense_cloud.meta
Out[3]: 2017-04-27 10:18:14 {'dense_cloud/density': '100', 'dense_cloud/depth_downscale': '2', 'dense_cloud/depth_filter_mode': '2', 'dense_cloud/duration': '1551.936', 'dense_cloud/resolution': '0.00200959661626811'}
PhotoScan.app.document.chunk.dense_cloud.meta
Out[4]: 2017-04-27 10:18:24 {'dense_cloud/depth_downscale': '2', 'dense_cloud/depth_filter_mode': '2', 'dense_cloud/resolution': '0.00231038693081674'}
both chunks were created in high but the altitude is different one was flown at around 100 to 120 m the other at 500m
however i have the idea it might have to do wit the points being classified
thanks a lot!
