Car scanning with Photogrammetry

A new technique we have been working on for scanning full colour reflective objects using photogrammetry.

This is our second test and there is still a lot of room for improvement, objects with multiple reflective layers such as headlights are a problem as you can see from the mesh but we should be able to solve this in the coming weeks.

For the purposes of this test we deliberately chose the hardest possible car to scan, reflective white paintwork, multicolored livery and lots of pure black shiny plastic, a photogrammetry nightmare to say the least!

We’re using AGI PhotoScan to process over 480 images resulting in nearly 1,000,000 Tie points and a Dense point cloud of 168,000,000 points

Once the scan is processed we end up with a fully textured 3D model consisting of about 11 million triangles, As I mentioned before there are still some issues with the lights and there is a lot of noise in and around hard to scan areas such as under the arches and along the bottom of the diffuser.

Full Body 3D Scanning using 80 x DSLR’s

This is the first test using our 80 x Canon DSLR full body scanning system. We are able to capture any pose in full colour in approximately 1/10,000th of a second. With this being our first test there is definitely room for improvement in terms of texture quality and capture volume.

Capturing a pose (5 Second body Scan)

We are working hard to reduce our full body scan time, initially we started with full body tests taking as long as 30 seconds using only 9 cameras, however over the last few weeks we have managed to bring that down to 5 seconds using a new 16 camera set-up with 2 more cameras for the face 18 in total.

Obviously the definitive solution is to buy 100 cameras, reducing the scan time to that of the shutter. However we are confident that a 20 – 30 camera rig is capable of capturing very high detail full body / head scans.

We are trying to keep our rig as minimal as possible at the moment we can pack it into a few cases which is great for portability.
