Multi-convergence problem with bundle
« on: February 05, 2016, 11:25:46 AM »

The bundle adjustment in Agisoft seems to work quite well for small block e.g. 500m x 500m for our data. But as the block size increases to around 1000m x 1000m, the bundle adjustment runs into multi-convergence problem. That is, it converges to a solution that's not correct, with patches of tie-points floating at heights which are obviously not where the ground structures should be.

We have pretty good knowledge of the heights (min, max) of the area that we are surveying. Is there any way that we can tell Agisoft to obey some height constraints during the bundle adjustment?
