Determining three-dimensional information from projections or placement of two-dimensional patterns

Abstract

Embodiments of a shape measurement system and related methods are disclosed. In some embodiments, the system places a two-dimensional initial pattern, which can be implemented as a standalone molding or can be attached to a light source or printed on an outfit, onto a surface of a three-dimensional object. The system captures a transformed version of the initial pattern in two dimensions that is distorted due to the varying depth of the surface. The system then analyzes the transformed pattern and derives three-dimensional information regarding the target object. The analysis, which can incorporate a calibration process, can rely on the projection nature of the light source, the isomorphism/non-isomorphism of the initial pattern, and other factors.

1 - 15 . (canceled) 
     
     
         16 . A system for directing movements of a target object, comprising: a processor;
 a memory that stores a definition of a configuration; a camera; and   
       a display screen, wherein
 the camera captures an image of a target object, 
 the processor determines whether the target object is in the defined configuration from the captured image, 
 when the determining indicates that the target object is not in the defined configuration, the display screen shows a geometric shape with a directional indicator to guide a movement of the target object, and 
 when the determining indicates that the target object is in the defined configuration, the display screen shows the geometric shape alone. 
 
     
     
         17 . The system of  claim 16 , wherein the geometric shape is a circle, and the directional indicator is a triangle where two of the vertices slide along the circle. 
     
     
         18 . The system of  claim 16 , wherein the display screen also shows text of no more than a specific number of words to explain the shown graphics. 
     
     
         19 . The system of  claim 18 , further comprising a speaker that reads the shown text in a voice. 
     
     
         20 . The system of  claim 16 , wherein the system is a cellular phone, a laptop computer, a desktop computer, a tablet, or a wearable device. 
     
     
         21 . The system of  claim 16 , wherein the captured image includes a pattern laid on the target object, and wherein the processor analyzes the projected pattern and determines three-dimensional information regarding the target object. 
     
     
         22 . The system of  claim 21 , wherein the display screen displays the three-dimensional information regarding the target object. 
     
     
         23 . The system of  claim 21 , wherein the display screen displays sizing information regarding the target object with respect to a wearable piece available in multiple sizes.
