Patent Images

1. the method for the absolute coordinates of the three-dimensional surface of a definite object, described method comprises:

  • Two illumination patterns through phase shift are projected on the described object surfaces, wherein each illumination pattern mark of encoding;

    Seizure is from the reflected image of the described illumination pattern of described object surfaces;

    Combination institute'"'"'s image of catching is with generation wrapped phase image;

    Separate the parcel phase image relatively by separating the described wrapped phase image generation of parcel;

    Generate the absolute phase image from the described parcel phase image of separating relatively;

    AndDetermine the absolute coordinates of described object surfaces according to described absolute phase image.
