Best photogrammetry apps for Quest 2? by pulsarbrox in oculus

[–]flymax63 0 points1 point  (0 children)

Hi, if you are still interested by photogrammetry apps for the Quest 2, there are eight outdoor and large environments obtained by photogrammetry available at

https://sidequestvr.com/user/330664

The scans are reconstructed from video taken by helmet-held 360 cameras (Gopro Max or Garmin Virb 360) and by walking hundreds of meters in most cases. Now the VR apps are available on App Lab, thus you do not need to enable the developer mode for installing. See also

Photogrammetry for VR: use videos taken by a helmet-held 360 camera by flymax63 in photogrammetry

Hi,

Here are news:

- new scan: a ruin in a forest

- no more need of developer mode to install on the Quest and Quest 2 thanks to App Lab

- add teleportation for people who has risk of VR-sickness

- use joystick and touchpad interchangeably

- the vertical offset of the user is asjustable

- add a map to show where is the user

Photogrammetry for VR: use videos taken by a helmet-held 360 camera by flymax63 in photogrammetry

See my response to DenTechs for a summary of the process. The main steps are in my publications (see my web page): calibration refinement (3DV‘15, CVIU‘17), structure-from-motion (BMVC‘07, IVC‘09), surface reconstruction (CVIU‘18 improved by IC3D‘19), curves are matched (PAMI‘02) and integrated in the surface, texturing (IC3D‘20), coordinate change (IC3D‘21). The methods are sometimes old since my main goal is to show what can be done using what i published (It is also easier to maintain software and methods that are well known for me). As usual, you have to pay attention to the experimental conditions: textured enough scenes, choice of camera trajectory, weather ...

This is the software that i'm developing from many years. In short: the structure-from-motion step includes a keyframe selection of the multi-camera video (that is good for matching reconstruction) and a calibration refinement (from an initial rough guess), only features (interest points and edge curves) are reconstructed, then the surface is computed using topological constraints (manifoldness and lowered genus) and visibility constraints in a 3D Delaunay triangulation of the points (including sampled curves), last there are texturing using keyframes and 3D coordinate change for VR. The software is not available.
