Laser Scanning Pain Points

Post by harrietb »

Hello everyone

I work in the marketing department for KOREC, a Trimble distributor for the UK and Ireland.

We've been running a poll on laser scanning pain points over on our LinkedIn page and would like to hear from the LSF community on this topic.

Entries from the UK and Ireland could be in with the chance of winning a week's free hire of the Trimble X7.

I don't mind the calibration time and cost, usually falls within expectation and we do it during convenient times. Large data set just requires smart decimation and splitting the data in smart ways.

The biggest thing for me that gives me the most pain is mirrors.
Reflection, refraction, windows and mirrors.

One of the biggest pain for me are software issues, like crashes two minutes before the finish line or missing nearby software functions that ends up in a lot of stupid and repetetive work.

For anyone finding that dealing with huge point clouds is a pain, could I suggest you sign the petition for open point cloud exchange. One of the biggest time wasters dealing with huge point clouds is translating them between formats, with lost time, lost disk space, loss of information and potential for failure. This is something that we as a community need changed.

100% this, by far the most time consuming factor while processing point clouds, also pretty expensive since it has to be done manually.

Hi Thomas & Leandre,

Do you have any sample datasets you'd be willing to share that include this kind of data, ideally in e57 format with setups. It is something I'd be interested to see if I could write an algorithm to solve, not sure that I could but I have a couple of ideas for flat reflective surfaces. Curved reflective surfaces such as polished hand rails could be altogether more challenging :?

Thanks,

Shane

Shane I am very busy at the moment but I will make sure to send you a scan of my living room/kitchen. I have a mirror wall and lots of windows, a tv and chromed fridge ;)
I will look to have the data sent to you by the weekend

Many thanks Leandre and no hurry, also very busy here so it will be a while before I get a chance to look at this. Ideally if I could get the data in a format which includes setups (or trajectory file) and images such as e57. I suspect possible solutions will involve distance from the scanner rather than coordinates.
