Yes, we have had a number of delays, mainly due to concentrating our efforts on our photogrammetery camera system.
We acheived our first 2D scan around 6 weeks ago, and are now testing a prototype 3D scanner. Its a resin printed system with nylon gearing, so not the best quality - but we hope it will be good enoguh for the testing we need to do, before moving to the CNC for the final version.
We are hoping to see the first 3D scans in the next week. I expect them to be fairly rough, but should be good enough to allow us to optimise the horizontal and vertical control.
Your paper is very interesting. In the oil & gas and renewables industries we often have a desire to optimise the LIDAR for a particular object of interest. The ability to increase point cloud density on that area is novel.
