ARPlanar Hack 1.9

Description

ARPlanar,
A different way to measure the environment!

The app has its own plane detection algorithm, capable of detecting and merging planes at a speed of 200 frames per second, including the vertex colors.
The precision is around 5 centimeters, and it can be configured in the app.

You can compare planes to see what's their distance and their normal orientation in Euler angles.
It is possible to obtain room approximate area by selecting 4 planes.

Every scene can be saved into a binary file using Menu -> Model -> Save.
Then the scene can be loaded anytime for inspection in AR or 3D mode using Menu -> Model -> Load.

It is also possible to export to OBJ files (colors are not included), or ASCII PLY (including colors).
The user can share the scene or the recording through AirDrop or see them to Files app.

The app is based on my previous work on my thesis diploma:
- find all the dominant planes in a point cloud
- merge similar planes into a global map
- measure distances from one plane to the other
- approximate the relative rotation and translation from one pose to the other

Features:
- plane segmentation
- plane merging in auto mode and manual mode
- project the plane points to the plane
- find distances by averaging the distance from the center of one plane to another
- export the map with their projected points or not
- load previously exported scenes and view them in AR or 3D
- record point clouds together with camera poses into binary files and replay them later

Enjoy.

Version history

1.9

2023-04-01

Split planes into small regions that are rendered using textures (TriTex)

1.8

2022-01-15

Fix font atlas

1.7

2021-03-10

Added record button
Added inches and feed measurement units

1.6

2021-02-25

Dislplay line segment length created by all selected plane intersections

1.5

2021-02-21

Display distance (depth) of the center point.
Display segment length of the detected floor polygons. Small polygons are discarded. This can be adjusted using Draw->min_poly_area. Its default value is 2 squared meters.
Display height plane differences for vertical and horizontal planes. Floor level is considered the lowest AABB of all selected planes.
Many other fixes and improvements.

1.4

2021-02-10

Added closed polygon detection for the floor plane. All the walls are projected and the area for each polygon is calculated.
The algorithm is capable of detecting polygons for 1500 line intersections in less than one second!

1.3

2021-02-03

Added a 5 second countdown for the AR session to be more stable. This applies also when the tracking is lost.
Manual merge has no limitation now. All the points of the selected planes will be merged into the first one.
Added "View Other" mode to ease selecting very close planes.
Optimized plane selecting by checking first that the OBB is first hit.
Optimized record saving and loading.
Made sure the app does not crash when the 3D font is not available on the device.
Other optimizations for supporting larger maps.

1.2

2021-01-26

Visual delight as planes get selected:
- instead of drawing OBBs for all planes, draw just for the ones that are selected
- find parallel plane pairs in the selected planes and show OBB size plus the normDistance between them
- don't use world axis for plane projection, but instead use OBB axis

1.1

2021-01-23

Improved plane merging using oriented bounding boxes (OBB)
Now you can exactly know the dimensions of walls by looking at the plane axis (up = green, front = normal, side = cross product of the other two axis)

1.0
