P20 Feedback

Post by jrbrown » Tue Feb 04, 2014 2:54 pm

We're currently in the market for a new scanner to add to our group. As of today, we run 4 phase scanners and have been approved funding for 2 additional. We'll likely purchase another 5010C however, before I commit, I'm curious about the P20.

I'm hoping that someone here would be willing to share their real world experience with that machine.

Specifically, I'm interested in:

Quality
Speed
Durability

Thanks in advance.

I am a Leica fan but recently Z+f 5010c and Faro X330 catch my eyes.
You may know that 5010c is same as leica HDS7000 in every aspect,I see some good quality scans from P20 though.
Interesting post.

Technically, the 7000 is "like" the 5010 ;)

I'm just curious about the P20 and how it's fared for those who own one as opposed to "it's the greatest thing ever and all other machines pale in comparison" sales pitch.

I just haven't heard a lot about the P20s, at least locally.

agreed... if you look at the chart i published in this post: http://laserscanningforum.com/forum/vie ... =20&t=6627 I'm not really sure what it brings to the table except self-calibration.

Hi,

We have had a P20 for the last year. We initially bought it to be a good all round scanner as it was touted as having very clean data. We have found this is only at range (over 20m and on a high quality settings, where it is excellent) At close range and low quality settings (under 6min scans) you get a noticeable ripple effect in the data. Its not noisy, but the ripple gives it a approx +/- 5mm deviation depending on the surface. We have also found that this ripple effect isnt the same. Multiple scans from the same location will have deviations, maybe its just be cause the data is cleaner that this effect is more visible??

We have found it a great piece of kit for long range outdoor scanning of externals of buildings and generally fixing our control around a site.

However it can seems very slow in comparison to a phase scanner especially when shooting in targets in the field. It all comes down to what you are using it for, big sites it is ideal. smaller sites where you want lots of quick scans it can be quite slow.

The other downside is the cameras is not great, it works ok indoors, but out doors with changing light contrast it can take a while to capture images and then when processing you can get very significant differences in contrast where the images have been stitched.

Again horses for courses, I like the ability to setup over control and also use cyclone to process everything. However the smaller size and HD imagery would make the 5010C a very tempting alternative.

Thank you for the information Ben. Your description is basically what I was afraid would be the case.

I got to use it a few times at my old firm. I used it for both interior and exterior work, and I have to say I was very pleased with the data, very clean on multiple surfaces at various angles and on many colors and how quick the unit worked. It is fast and since it can collect images, i am fine with a longer overall setup time than the 6000 that we abused day in and day out.
I was never an "on-board" fan as I liked to see my data on a laptop as it was collected, but I found myself without any instructions very easily working this unit, and then manually locating some targets that we had moved around. I did not notice any of the ripple effect that was previously mentioned. I do have to say that I noticed a difference in screen quality compared to our C10.
I was actually impressed with the camera and coloring of the cloud but I did find that i had to manually adjust the exposure to get good photos though, but i was able to get good photos indoors and outdoors. I did find though that the files are much larger than anticipated, which caused a problem downloading to a laptop. Was not expecting that.
In both jobs, I would have loved a smaller, lighter unit as we had to navigate scaffolding for several floors and ladders. But I trust the data that comes out of the Leica units.
You could probably have multiple people from the same office use this unit and get totally different opinions especially if the office has scanners from other vendors available for use.

Hi,

I use this post to ask a question : Do you know how weighs P20 pelicase? And what is total weight of P20+batteries+Pelicase.

Thanks a lot

I recently hired a P20 scanner and found that the operation was pretty much the same as the C10 (easy and fast). Although the scanning time is faster, the data contained much more noise - although this can be mitigated by increasing the quality and filtering on import. The trouble is - if you increase the quality then the scans take much longer.

For complex plant type work, where targets can be automatically extracted from the point cloud - the scanner offers great time savings. Sadly though, if you fine scan targets - it takes as long (if not longer) than on the C10. In my case we did not see a massive increase in productivity as fine scanning the targets was taking 6-7 minutes.

Annoyingly, the version of Cyclone that we use is not compatible with the new scanner, so we had to hire a license. This was irritating as I just had to export all the scans and then import it all back to my older version - otherwise I'd not be able to return to the project after the hire period. I dont think that I can update the firmware on our C10 either - without un-necessary upgrading.

The camera on the P20 takes noticeably better images than the C10 (probably due to auto white balance). Sadly though, on automatic exposure, the tiles are all exposed at different levels, so you get an ugly patchwork effect that cannot be nicely blended.

We are actually looking into purchasing a P20, but at the moment I am leaning towards the ZF scanner as it has an in-built HDR camera. Has anyone any experience of the Z_F_IMAGER_5010C_E?

Please note this is a UK-related post...

From a sales perspective the P20 is the most successful scanner we have ever sold into the UK market. I am not going to divulge numbers here, but it contributed to the best year yet for UK HDS in 2013 and looks set to perform incredibly well into 2014 - and we have also received orders for multiple units: we just sold 5 units to one customer alone and another is set to buy 3/4. In particular the education market has adopted it incredibly well and now with the introduction of the P15 we have a good entry level product for those markets where we would not normally be selling to.

A major plus side versus a Z&F solution is turn-around time for service/repair or calibration. We also have a fleet of >20 scanners available (C10's/P20's, HDS7000's and HDS6xxx's) to assist where customers scanners are back at the factory or they need additional units for example.

There are major steps going on to improve image quality (across all manufacturers) and the latest P20 FW was a good step forward with the white-balance options. If you have a P20 and have not yet upgraded, please do so as you will see much better image quality, colour rendition and less 'patchiness' (for want of a better phrase!).

In addition to this, we have what I believe to be the largest and most experienced team of any manufacturer (Myself, Steven Ramsey, Charlie Matthews, Graeme Laing, Jack Glauser, Kate Strange-Walker, David Ellis and Nicollette Beggache) to help support you and 2 fantastic dealer channels who are both very knowledgeable and dedicated.

:D
