3d pointcloud and Mesh from 2D Photos

As an experiment I have produced a 3d point cloud and mesh from a series of 2D photographs to compare with other survey methods I use at work to assess the relative accuracy of this method of modelling.

Using photogrametric principles software can now reconstruct/model 3D objects just by using overlapping photographs of the object. If the results bear up then this will produce quite a time saving on site for some projects at work.

The key is to make sure there are plenty of photos with sufficient overlap.

Below are screen grabs of the resulting model.

When this is taken to the next level you can get some good results. 3d model of houses and grounds shows some more potential
