TruView
Hi,
Can anyone share their experiences/thoughts on the above product. Will it become the industry standard PointCloud 'delivery' mechanism for clients?
Any feedback would be appreciated.

Re: TruView
Jason,
I'm a big fan of TruView.
It allows the client to get a 'real world' feel for the scanned area or object, plus it can be delivered almost instantly for them to use while you are still working with the data set i.e., modelling, CAD, etc..
They can also take simple measurements and mark up the data too.
Regards
Phil

Re: TruView
An interesting way to use Truview is in later versions of Autocad is to attach a hyperlink to objects representing scan locations in the drawing so that you can load the nearest Truview to the drawing you are carrying out.

Re: TruView
Has anyone got any live Truview examples on there company websites as demo's or is everyone just using it for secure client logins only? I am thinking of posting one up for people to have a look at and play around with if they haven't already seen it in action.

Re: TruView
True view is a very nice concept, however caution does need to be noted. Whenever you are trying to extract 3D measurements from 2D images caviats need to be put in place. The potential for novice users extracting incorrect dimensions from the data believing them to be right could cause significant issues for both users and suppliers of data.
When selecting edge points within true view there is the potential to have snapped on a point that is in the distance, rather than the expected edge.
Leica have since incorporated a metadata feature but as I understand it the metadata is only displaying how close the nearest point to your selection is, its not actually confirming that you have selected your intended point.
The image below hopefully clarifies what I mean. The brick edge you are selecting in a 2d image might actually correspond to a point on the building beyond. The metadata might display that you are within 20mm, but that is 20mm of the point on the facade in the distance.
Of course this doesn’t apply to all measurements, for example if you are taking the dimension of one brick you are not going to get any issues, unless its on the edge of the wall.
This is how I understand the process, please correct if wrong.

Re: TruView
Andy,
thankyou for the post high-lighting the potential 'risk' with using TruView...something I hadnt considered and will try it out on some sample data.

Re: TruView Plugin
When will a plug-in be available for other web browsers i.e. firefox, opera, etc?

Re: TruView
I think that TruView is a good idea... But...
Clients usually want to see the data very quickly, and producing a good looking TruView and uploading it to web space can be time consuming. It can also take the clients attention away from the highly accurate and cleaned / trimmed point cloud they are actually paying for.
If you scan something and the laser hits the edge of an object the light information sent back to the scanner will be confused into putting that point, in an incorrect position. Or quite simply, you get a lot of noise on edges, even with the best scanners. Then you have snow, rain, steam etc - This all leads to noise in the scan that can not be seen in the TruView. Because the TruView will only show what is happening from the scanners point of view - The point normals are all facing the view point.
In perfect conditions a TruView presentation can be a very usefull tool. In the wrong conditions you could lose your clients confidence.
I would be inclined to take out the measurement aspect altogether, As survey companies are not in the business of producing in-accurate information if they can help it. And just use it as an online viewer.
