3D ShowcaseMultiple Floors

Multi-floor Misplacement240

RenderingSpace private msg quote post Address this user
Hey guys I've run into trouble for the second time with floor misplacement in processing. This home has 3 levels; Basement, Main, 2nd. However, each floor has step ups or step downs. And the main floor has somewhat of a split entry with the den and living room being a few steps below the rest of the main floor.

The den and living room got thrown into the basement and oddly, the sitting room on the 2nd floor got put into a 4th floor.

I always start from the bottom floor and mark things as I go. Has anyone else had trouble with this? It would only be noticeable now that there's a multi-floor toggle.

I had similar problems with a big 10,000 property I did recently. The problems went away after I made a minor modification and reuploaded, though, so it wasn't a big problem.

However, now that I think of it, I noticed that in the Workshop view, the property had somehow become 4 levels instead of just 3. It shows up as 3 in the 3D Showcase, but 4 in the Workshop. The 4th level in the Workshop is just a short series of scans from one of the other floors. Weird but doesn't really affect anything.

Craig that's strange because a couple weeks ago I had misplaced floors and reuploading it with only minor tweaks solved the problem. It's still a mystery to me why changing a little bit of trim would have that great of an effect.

This is just my observation... It seems your camara is placed way to high. Also for areas with just a couple of steps I would adjust the hight of the camara acordingly I am gussing that might be causing some confusion for it. I dont have a solution to your problem, but making some alterations to the scan it self and reuploading could possibly solve the issue.

Hope you can get it fixed without having to re scan the place.

cheers

Thanks for your response Mike.
I'm 6'1" and I keep the cameras sensors at about my chin. How high do you keep yours?

I've tried raising it and lowering it for the 1 or 2 steps but that's obviously not possible with the split stairs.

I think I'm just going to send it with the toggle disabled.

Id say about a half a foot maybe a foot lower. If you look at your doorways they look very low like you are almost going to bump your head going through it. to get a better view I have to look down more then i should (I feel) I had similar issues I did not like with my scans so i started setting it lower and it seems to produce dicent results.

I always keep the tripod at the same height for every scan, that way if you need to return to the property to rescan a room, you know what height it was at. So, I fully extend the legs and have the center post at the very lowest it will go. I did purchase the recommended tripod and am very happy with the quality of it.

Judy, I just wanted to mention that Tim shared with me that I would be well advised to change my tripod setup. I was doing exactly as you are but he suggested to only extend one set of the legs and raise the center support all the way.

This also puts the camera at the perfect scanning height it seems.

After thinking about it, it sure makes sense to have less reach on the legs for a number of reasons. I was having trouble getting through some doors and narrow hallways. Plus I think that you may have less chance of the legs showing in a scan.

I will be using Tim's suggestion next time out.

Charlie, the center column is your last resort for raising the camera. Short legs and extended center column is the least stable configuration for any tripod.

The legs won't show in the scan; the software cuts out a rather sizable footprint. Yes, it can make getting through doorways a bit more awkward, but that's a very minor tradeoff in return for a much more stable base for your $4,500 investment.

Here is a model that also has a number of split levels: https://my.matterport.com/show/?m=fK14dWqBepq

You'll see it also has some of the same problems.

However, it was working fine a month ago when I originally ran it.

I am going to reach out to Matterport Support and see if I can't get an answer. I bet the updated algorithms are trying to automatically delineate floors.

I am 5'7" and generally keep the top of the camera at eye level or just lower. Also, you are probably running too many scans on the staircases. I find on a typical stair case I can run one scan at the bottom, another a 1/3 of the way up, 2/3s of the way up and at the top landing (the top landing then becomes the first scan of the next floor.)

I generally go up 4 steps at a time, unless there are alignment issues. And I keep my camera's sensors between 4.5 and 5 feet above the ground. With the higher POV, it just seems like I'm always wanting to look down.

When I navigate I never look down because I use keyboard navigation keys rather than the mouse but I can see how many people would use the mouse to navigate and wouldn't want to be looking at the ground so often. I'll try lowering my camera at least a half foot.

I highly doubt my problem is caused by doing too many scans on the stairs. Rarely are things made worse by doing too many scans. I find it best to do more than remove as necessary. If you take a look at my model, the upstairs is just the master suite with a sitting room 2 steps up.

I don't have a clue why it would interpret that as a 4th floor! Of course I could adjust the tripod to keep it consistent but then it would only be 3 feet above the ground on the high parts.

Still haven't heard back from MP.

Can you upload screen grabs of the three floors in this thread? These screen grabs may be helpful to solve the mystery.

And, welcome to the Forum.

Best,

Dan

For clarification, what I mean by "screen grabs of the ... floors" are the mini-maps from your iPad that show the scan numbers and trimming.

I suspect that the challenge may be trimming on one floor affecting another floor.

If you would like to test this, duplicate the model. Then, remove all trim. Then re-upload the model.

Thank you in advance for posting the mini-maps here.

Best,

Dan
