Discussion with Professor

TDEI Workspaces

TDEI Workspaces uses a lot of resources from OSM.
GoInfoGame communicates with the ‘Seattle OpenSideWalks Dataset’ .

• Why only with the Seattle subset?

We have our own OSM-style database (PostgreSQL). Thus, running own version of OSM.
We can create a different schema in the backend database, and thus separate work groups and their data.

Swagger UI Documentation

Not required.
Our app is not going to use the Swagger UI API.
GoInfoGame for example, simply fetches data from the private OSM database.

GoInfoGame

GoInfoGame fetches the existing elements in the current area, and accordingly assigns quests to the user. These quests are about providing information about certain points of interest by manually analyzing them (something that iOSPointMapper may be able to automate).

Existing iOSPointMapper plan

Unlike for GoInfoGame, we do not need to fetch the existing elements in the current area, and map the segmented elements with the existing ones.
For now, we are fine with the addition of the segmented elements as new ones, even if they are already present.
The data from iOSPointMapper is going to be so sparse, that it may not affect the overall database.

OASIS for Reference

Need to check with Ricky Zhang on if the OASIS source code is available on Github.
Some concepts such as homography transformation and centroid tracking can be useful for reference.

Points of Interest Classes

Which points of interest are being reliably segmented?
This will be hard to answer as of now, since there are some issues with the coreml converted models of both ESPNetv2 and DeepLabv3.
Audiom by XR Navigation can serve as a reference for which classes would be useful if done by iOSPointMapper.

• Classes (points): Light poles, benches, fire hydrants, bus structures (e.g. stops), bicycle areas (e.g. parking)
• None of the current models would support that.

Should we try VLM models?

Outreach Next Steps:

1. Set up a meeting with GoInfoGame team to discuss API transmission to POSM dataset
2. Reach out to Ricky Zhang to check if the source code for OASIS exists

Update:
Received the source code for OASIS
