VZ400i for mill as-is

Post by kpob46 » Tue Jun 11, 2019 4:02 pm

Hello everyone,

I have surveyed several mills at my company. I have a workflow using two Faro scanners in concert with spheres and checkerboard targets. It has worked fairly well but each position takes about 8 minutes per position. I was curious if anybody has used a Riegl scanner with the camera attached for similiar projects and using the targetless workflow.

Hi there,

There are lots of police forces in the UK and elsewhere using the VZ-400 and VZ-400i for crash scene capture, all without using targets for registration.

Setup and scan time per scan position is around 1 minute, depending on density. Using a wheeled tripod makes it really quick.

you can dump your spheres in the bin. the riegl is top-notch.
scans extremely fast, no leveling, pics while scanning. You can do a lot in a short period of time. Riscan software is also heaven to work with.
the only drawback is the weight of the instrument.

I do almost everything with my riegl, only small indoors and where the ceilings are very important i use my old tx5

Hi Joe, thanks for the response.

I should have been a little more specific. We currently own a VZ400i and use it lots underground and outside on surface. I was wondering about the viability of using it inside a building, such as a mill. The areas are tighter and I am concerned with its limited field of view compared to a Faro. I am also concerned about accuracy with targets vs targetless. It would speed up my progress greatly if I could use the VZ400i with targetless registration and get similiar results as two Faro scanners.

Sounds like I'm gonna get fat not having to run back and forth moving scanners and spheres :lol:

it is a break even event. the weight if the vz400i compensates for the spheres

Lieven,

I am assuming if you use your TX5 along side your VZ400i, would your workflow be similar to this:

1. Register TX5 data in Scene (target or C2C)
2. Export from Scene
3. Import into Riscan as a single scan position
4. Extract plane patches and MSA into VZ400i data

i do the excact opposite :D

i export the scans from riscan with the data i want to use to georerefence the tx5 data.
i make a cluster with the imported few riegl scans in scene and c2c with the tx5 cluster.

i then export the tx5 cluster to e57 or laz for further use in pointcab or other software.
i must test the other way like you describe once i find some time.
