USE OF SURFACE RECONSTRUCTION DATA TO IDENTIFY REAL WORLD FLOOR

摘要

In a virtual reality or mixed reality environment, an HMD device is configured to use surface reconstruction data points obtained with a sensor package to identify a location of a floor of a real world environment in which the device operates by sorting the data points by height into respective buckets where each bucket holds a different range of heights. A bucket having the greatest number of data points that are below the height of a user of the HMD device is used to identify the height of the real world floor, for example, by calculating an average of height values of data points in that bucket. A floor for the virtual reality environment may then be aligned to the identified height of the real world floor.

1. A method performed by a head mounted display (HMD) device to identify a height of a real world floor, the HMD device supporting rendering of a virtual or mixed reality environment, the method comprising:
obtaining surface reconstruction data associated with a real world environment adjoining a user of the HMD device; classifying surface reconstruction data points by height; sorting the classified data points into respective buckets; selecting a bucket having a greatest number of data points that are below a height of the user; and identifying a height of the real world floor relative to the user based on the data points in the selected bucket.
