Portal Scanning Guidelines?

AkceptorUAAkceptorUA ✭✭✭

Hey, are there any guidelines for portal scanning?

Sure, one can simply record those videos and work towards a badge but I'd like to provide a significant value per each scan, not just waste the data

In-game hint asks about walking around a portal (if possible) but as I know from my previous 3D scanning experience it worth to do these things as well:

  1. Change distance to portal fir better texture resolution
  2. Capture with tilted camera
  3. Capture the top of the waypoint (obviously you can't capture the top and walk around)
  4. Capture the place of connection portal to the ground

In addition sometimes it's better to have two separate captures instead single one (in case of some obstacles).

In addition if the wayspot is flat (e.g. mural or graffiti) its quite impossible to walk around so we should select proper angles for starting and finishing captures.

What if some objects (that are not related to the portal) appear in the camera view? E.g. trees or just branches around the wayspot in the park... What about moving people\cars in the scene background?

Any advices of scanning wired structures like this?

  • Oh, I have already thought about the problems with trees and plants in the picture, also about objects that are too big to walk around them. It would be interesting to know if it is sufficient to scan single parts of a larger or partly hidden wayspot and put them together in the end or if it is really necessary to scan the wayspots as completely as possible.

    So far, they've said it's best to scan portals that you can walk around (like statues, monuments, etc). But if you can't, a 180 degree scan will do. And you're allowed to do multiple scans of the same portal. They've also suggested doing scans at different times of the day, or in different weather conditions if possible.

    There's at least one portal near me that's such a big building that I can't be close enough to scan it without being so close I can't get it all in the viewfinder at once or walk round it all in the time allowed.

    Some guidance on what we should do for flat objects like trail markers or awkwardly shaped things like football pitches might also help us help you.

    The guidelines for portal scanning can be found here: https://niantic.helpshift.com/a/ingress/?s=portal-network&f=portal-scanning&p=web

    ...but they don't answer any of the things we're asking here.

  • AkceptorUAAkceptorUA ✭✭✭

    Yep. Those guidelines are like any programming tutorial on the Internet teaching you how to write simple helloworld program. And in real life things are more complicated.

    Even for statues its not so easy to find one without trees and people around.

    Plus we can't see the result of the data processing. I have a bunch of portals nearby I submitted scans for. But I never know if those scans were good enough, I don't know if they collected enough data points or they need more data from some specific point of view.

    Basically I don't see thing like this:

    So its kinda blind process

    Regarding large buildings, they do say in the scanning guidelines: "If the Portal is too big or too far away to capture with a single scan, try scanning the Portal with multiple scans, keeping some good overlap between each scan."

    I'm not sure what you mean by a "flat" trail marker. I've scanned several things in my local greenspace which are like trail markers. Posts with a map on one side. I've still scanned all around them, and from different distances.

    I'm not really sure a football pitch is a scannable object. But isn't there some actual object that's the portal picture, such as goalposts? Otherwise the submission is just grass anyway.

    I don't think every portal would be able to be made into a 3D model. For example, you could surely make a 180 degree scan of a mural, but what sort of 3D model would you want from a mural? Nevertheless, I say scan all the things. Make multiple scans from different distances and heights. Give Niantic the data and they'll give you a badge.

    these are good points passed on to the team. we'll post more detailed guidelines.

    And what else would be really nice is having an ability to see the scan data already present. Maybe published just by you or published by people per-portal. Maybe some hints like `this portal lacks scanning from South-East` thing to point people to the best ways of improving data quality.

    And maybe some way to specify that portal is 2D structure (mural or plaque) during scanning so that processing will be simpler

  • aceace ✭✭✭

    @AkceptorUA yes, different kinds of structures (buildings, statues, 2d signs and plaques) call for different approaches. passed on. expect to see some clarifications.

    There are two pieces of information that I'd like to know before I scan a portal (or scan it again):

    1. Number of scans have users contributed already. I'd like to know whether a portal has no scans, or dozens.
    2. Some sort of "health meter" that indicates whether the portal scans have enough data to work with, or if the data are good enough quality, or if more scans are needed.
