THREE-DIMENSIONAL RELATIVE COORDINATE MEASURING DEVICE AND METHOD

WIPO Patent Application WO/2013/005244

A1

A three-dimensional relative coordinate measuring device (90) is provided with: an image acquisition unit (100) that acquires a first acquired image obtained by capturing three reference points from a first perspective with an image capture device; a perspective projection angle extraction unit (120) that holds information on a pixel perspective projection angle for each pixel, and uses said information to acquire three first reference perspective projection angles, which are pixel perspective projection angles corresponding to the three reference points projected by the first acquired image; an inclination angle calculation unit (130a) that uses the relative coordinates of the three first reference perspective projection angles and the three reference points to calculate a first inclination angle formed between a first imaging plane, which is an imaging plane of the first acquired image, and a reference plane containing the three reference points; and a relative coordinate measuring unit (130d) that uses the first inclination angle to measure the relative coordinates between either of the three reference points and a target point.
