Three-dimensional imaging system
First Claim
Patent Images
1. A method of determining camera position for scanner output with scanned image frames of an object, the image frames representing three dimensional dense data sets, the method comprising:
- determining a first, tentative camera position from a plurality of image frames taken after one another in time,determining a second, rough camera position by performing dense information set matching between two image frames in positions capable of being matched as provided by the tentative camera position,after determining the second, rough camera position, then making a first aggregation of the three dimensional dense data sets using the second, rough camera position determination, wherein the first, tentative camera position is not used in making the first aggregation, andprocessing point collections from the plurality of image frames with defocusing equations to produce three dimensional data.

Abstract
Hardware and software configurations, optionally, for performing profilometry of an object are disclosed. An advantageous imaging device is described. An advantageous approach to determining imager position is also described. Each aspect described may be used independently of the other. Moreover, the teaching may find use in other fields including velocimetry, etc.
