Image based angle sensor

摘要

A method of image-based positioning is provided. The method comprises: (A) providing an image-capturing device integrated with an object; (B) providing a pattern-generating device configured to generate a set of patterns; (C) locating the pattern-generating device in a field of view (FOV) of the image-capturing device and capturing an image of the pattern-generating device; (D) generating at least one set of pattern data by using the captured image of the pattern-generating device; and (E) processing each set of generated pattern data by using in order to generate an altitude and/or angular coordinates of the object.

1. An apparatus for image-based positioning of an object comprising:
(A) an image-capturing device; (B) a pattern-generating device comprising a structure having a first pole and a second pole opposite of the first pole, the structure includes a gradient pattern that extends from the first pole to the second pole, wherein said image-capturing device is configured to capture at least one image of said pattern-generating device while said pattern-generating device is located outside of said object and separate from said object; and (C) a processor configured to generate at least one set of pattern data by using said at least one image; and configured to analyze each said set of generated pattern data in order to determine angular coordinates of said object.
