Keeping It Real

Our Metashape Standard course has been running for about six months now and so far feedback has been very positive.

That should not mean we sit back and think the work is over – it isn’t and we like to keep things as fresh as we can, adding content when we can. One group of students – all very much new to photogrammetry – asked if we could put together a brief end-to-end video that stepped through the basics.

We thought we could go one better for this group and make the training material as relevant as possible. Why not feature a scene they will need to survey for real?

Captured by drone the road junction is a perfect real-world example we like to teach and train with

Close to where Simon lives is a closed area of road, complete with white line markings and tyre tracks across the grass – very relevant for forensic collision investigation training.

Details in the road are exactly the same as those found at a live collision scene

It’s a small dataset – just 90 images or so – but its enough to teach principles and not leave students waiting for a bigger scene to finish processing.

For Professional users a DEM and othophoto can be added too – this is covered in the Pro course

We do like to keep it real and make sure training is relevant and as close to the real world as possible. After all, photogrammetry is all about documenting what is around us, isn’t it?

As its shot by drone the dataset carries GPS data. Its not derived from RTK but for the immediate needs of students this is of lesser importance. What’s needed is a quick intro to bring people who have never used photogrammetry up to speed and realise its benefits and potential. Absolute accuracy, recursive refinement and other benefits can come later.

This material may well feature in the Metashape Professional online course for surveying and forensics – as endorsed by Agisoft themselves – at some point in the future.

In the meantime, here’s a view of the orthophoto and DEM outputs:
