Title:
THREE-DIMENSIONAL MEASURING DEVICE AND THREE-DIMENSIONAL MEASURING METHOD
Document Type and Number:
WIPO Patent Application WO/2014/073590
Kind Code:
A1
Abstract:
A three-dimensional measuring device comprises: a plurality of cameras (2, 3) containing imaging elements for which the exposure timing differs by line; a light projecting means (4) for projecting light toward a moving body (8); a detecting means (5) for detecting that the moving body (8) has reached a measurement position where the same is measured by way of the plurality of cameras (2, 3); a controlling means (6) for controlling the exposure of the plurality of cameras (2, 3) so that all the lines of the plurality of cameras (2, 3) are in an exposed state and for controlling the light projecting means (4) so that light is projected during the period that all the lines of the plurality of cameras (2, 3) are in the exposed state; and a three-dimensional distance calculating means (7) for calculating three-dimensional distance of the moving body (8) on the basis of an image captured by the plurality of cameras (2, 3).
