Scan a car with p40

Post by Ioannis » Sun Jul 14, 2019 10:36 am

Is it possible to scan a car outside with Leica P40 ? I worried about the metal that is polished. Also can I combine it with photogrammetry to take photos inside of it? At least what accuracies can I accept ?

We used a p40 for a large number of vehicle scans it works well, sometimes you need to try several scan positions to get the details you need. Dark coloured shiny cars being the main problem.

Use Magnaflux developer spray, or similar, on chrome or shiny black areas. Most scanners struggle with that. It’ll make a bit of a mess as it’s a spray powder. I used it for vehicle accidents and for the most part my subject vehicles were already wrecked. Most other colors came out ok though.

Baby powder mixed with methylated spirits
In a spray bottle works great for shiny surfaces. The methylated spirits evaporates and leaves a fine coating of powder.

We would use one of our AXE 3D Scanners for this application, it has built in photogrammetry and the need for spray is very low if required at all...

If we did need to use spray we would recommend the AESUB Blue - it disappears after an hour without leaving a residue.

We have scanned well over a couple of hundred vehicles with this system in all manner of locations, quick, easy, precise.

The P40 is actually quite good at scanning cars with reflective surfaces. Just do lots of setups around the car to make sure you get all the detail.

You could scan inside the car with the P40 and use the images from the scanner. Although the scanner might be a bit bulky for that.

As far as accuracy is concerned - I reckon about +/- 6 to 8mm
If you don't see that there is nothing, then you are kidding yourself.

We have scanned several cars and have had good results with our P40's. Our C10 does do a better job on black cars, but we keep the P40 scanners on a higher setting to get more coverage. Try setting 6.
