eCPD - Photogrammetry vs SfM vs Lidar

Date & Time

Tuesday, 22 Mar 2022
4:00 pm - 5:00 pm

This is a recording of a live webinar held on 22 September 2020
Summary

Modern surveyors are spoilt for choice – in addition to traditional surveying techniques, drones have dramatically lowered the cost of aerial acquisition and thereby massively reduced the project size required to make it viable. With the advent of lightweight Lidar systems even aerial laser scanning is now an option for relatively small jobs.

However, it is important to understand the characteristics of each technology beyond what’s printed on a marketing brochure in order to make an informed choice on the technology to use and how to apply it.

For example, the processing times and accuracy obtained with modern photogrammetry and SfM packages can be extremely sensitive to the settings used and the algorithm chosen. Without a clear understanding of how they work, practitioners may be unaware of the trade-offs they are making and the impact that is having on the quality of the data generated as well as the time required to generate that data.

In this talk we took a peek inside the black boxes to look at how they work and use real-world projects to illustrate the advantages and limitations of each option. Guidance was also provided on the factors that influence which choice is the most appropriate in a range of different circumstances.

Speaker:

Jason Birch, ADAM Technology

Jason joined ADAM Technology as a developer in 1996 when the 3DM technology was still in its infancy, then became Product Development Manager, R&D Manager, and finally Managing Director in 2004. He and his team have been at the cutting edge of photogrammetry for two decades and are always interested to find new applications of the technology.
