Too many scans?1263

suncoastskyview private msg quote post Address this user
Many thanks in advance for answers to these questions:

I've seen comments here regarding "too many scans". I'm quite confused about that. I was under the impression that the more scans the better.

How do I know if there are too many? What are the advantages to less?

Is there a way to observe the model to determine what scans are superfluous? Then, how do I delete them?

How do I plan the scanning to avoid too many? I've been spacing them 5-8' apart except for doorways, where I scan 18" from each side of the threshold.

I think too many scans can make it slower to load and be distracting when in the showcase.

For the showcase walk through mode I think scans should be relatively evenly spaced to allow for a consistent pace and along natural walking paths to mimic an actual tour of the space when viewing it in showcase. Higher density scans can produce a better model for the doll house and floor plan views in the showcase mesh view in workshop but not necessarily in the walking view. You can use a higher density in areas of greater interest and complexity like kitchens, gyms, or machinery for examples.

You can disable and hide extra scans in the administrator's workshop. http://matterport.com/wp-content/uploads/2015/03/Matterport_Workshop_2.0.pdf

Ultimately the scan density and placement is one of the few artistic freedoms or dare I say skills, we can use to differentiate ourselves from other Matterport users.

Good luck!

When you're planning your project do as many scans as needed to expose as much of the area as possible.

You want to do that to eliminate the vacant "black" areas in the dollhouse view. Shoot Behring doors, raise and lower the camera, whatever you need to do to maximize the data.

Don't delete any scans. Hide the superfluous scans for a smooth walk through. I usually hide half of the scans I take.

Hope that helps!

The goal isn't to go into a home and do too many or too few scans. The objective is to be as efficient as possible while creating a quality scan that is both easy to navigate in the walk-through view and complete in the dollhouse/floor plan view.

In my experience as both a viewer and scanner, I think less is more for several reasons:

(1) The longer you're in the house, the more time you're wasting for yourself, the agent if present, and homeowner. Being in a home for 4 hours instead of 2 can be annoying for some agents.
(2) There are many places in a home that you really don't want to spend a lot of time in like hallways. Being able to zoom down the whole hall is actually a better experience then having to click 5 times. The same is true with stairs.
(3) In vacant rooms, you don't need 10 scans just for the sake or spacing them out.
(4) Load times. The less scans, the faster it loads!

This is the summary of Matterport's recommendation, similar to what @Lbelland stated above.
Source, with full explanation in the context of creating a complete mesh
"As you’re creating models now, keep in mind that this data could be used for a number of applications in the future. That’s why it’s so important to scan thoroughly, and try to get behind furniture and into every nook and cranny. (Remember, if you over-scan, you can still turn those positions off in Workshop to produce a clean walkthrough experience, while keeping the advantage of all that great mesh data.) Even smaller rooms like a bathroom or laundry room should have no fewer than 2 scan positions, so that any point in space is seen from multiple angles. This generates the best quality geometry.

We see too many otherwise great models with bits of rooms or parts of couches missing. Snagging that one extra scan position is always worth it!"
