Sony patents system that fixes 3D laser scan errors for virtual displays
Sony describes a system that uses frequency-modulated continuous wave (FMCW) sensors to create 3D maps of real-world objects. It identifies specific areas within these maps and corrects their coordinates to ensure virtual objects appear in the right place.
In the filing’s own words
An information processing apparatus according to an embodiment includes: a recognition unit ( 122) configured to perform recognition processing on the basis of a point cloud output from a photodetection ranging unit ( 11) using a frequency modulated continuous wave to determine a designated area in a real object, the photodetection ranging unit being configured to output the point cloud including velocity information and three-dimensional coordinates of the point cloud on the basis of a reception signal reflected by an object and received, and configured to output three-dimensional recognition information including information indicating the determined designated area, and a correction unit ( 125) configured to correct three-dimensional coordinates of the designated area in the point cloud on the basis of the three-dimensional recognition information output by the recognition unit.
What exactly they claim (claim 1)
1. An information processing apparatus comprising: a memory storing a program, and at least one processor configured to execute the program to perform operations comprising: performing recognition processing based upon a point cloud output from a photodetection ranging unit using a frequency modulated continuous wave to determine a designated area in a real object, the point cloud including velocity information and three-dimensional coordinates of the point cloud based upon a reception signal reflected by an object and received; outputting three-dimensional recognition information including information indicating the determined designated area; correcting three-dimensional coordinates of the designated area in the point cloud based upon the three-dimensional recognition information; and generating a display signal for displaying a virtual object based upon the three-dimensional coordinates of the corrected designated area.
