Years ago, studying photogrammetry in survey school there was a question asked along the lines of "why do we need to know this - we will never use it". Now only a few decades later it seems as though photogrammetry is becoming mainstream and proving its real worth. The advances are coming from the 'app' developers to fill demands for those using 3d printing and the like but the benefit is being felt in the engineering industry.
The real advances will come through mobile phones because that is where the highest number of users is (See http://www.stockpilereports.com).
Right I thought this will lead to the eventual death of laser scanning as you can’t make a laser scanner that will fit in a phone. But no, the development in this is apparently being led by big companies developing driverless cars who are working on very small scanners (see blog.lidarnews.com/low-cost-solid-state-lidar/).
This suits me as if the weight of the instruments come down then the weight of them combined with me can remain constant.
