As you open the app, a gif appears to guide you on placing the ground detection marker on the floor.
Detection of the floor on which the object is kept is critical and enables bounding box placement. In this stage, a floor marker appears on the screen that can be moved adaptably over the various horizontal surfaces in the scene.
The marker (mat) has two states:
Detection in progress (marker takes the shape of corner angles for the initial few seconds)
Floor detected (marker appears like a whole mat)
To begin the process:
face the front of the object to be captured and
point the phone towards its base in front of the object
This should normally result in quick floor detection (the marker appears in the shape of a mat). If detection takes time (corner angles) move the phone slightly from side to side before focusing on the base of the object, to make detection easier.
Important:
Surface detection works well with textured surfaces, such as a carpeted floor or a table with a textured table cloth though they should be perfectly flat and with no wrinkles or surface aberrations.
It is best to avoid glossy and plain surfaces to place the object on. White surfaces might lead to problems with discovery.
