Photogrammetry – comparing reconstruction parameters

This test aims to determine the effects of different settings for dense cloud reconstruction in Agisoft Photoscan, and how they relate to processing time and accuracy.

To do this, I contructed three dense point clouds under different accuray parameters (High, Medium, Low), where the High-accuracy reconstruction serves as the reference point for the comparissons (processing time: 2h54min).

The subject used is a 5 x 10 m excavation square captured b.o. of the Heliopolis Project during the Spring 2016 campaign.

The comparisons where conducted inside CloudCompare using a nearest neighbour approach.

Processing time: 29min

Processing time: 7min
