摘要： A calibrated three-dimensional optical measuring apparatus for the three-dimensional measurement of geometric parameters of a rope has a frame defining and arranged around a rope receiving cavity. A plurality of image acquisition devices is configured to acquire a plurality of digital images of at least one region of an outer surface of the rope. The image acquisition devices are fixed to the frame and arranged around the rope when the calibrated three-dimensional optical measuring apparatus receives the rope in the rope receiving cavity. An attachment device is configured to constrain the calibrated three-dimensional optical measuring apparatus to the rope in a relatively translatable manner with respect to the rope. An electronic digital image processing device is configured to process a multiplicity of digital images and obtain a three-dimensional photogrammetric reconstruction of points of the digital images of the rope acquired by the image acquisition devices.

摘要： A calibrated three-dimensional optical measuring apparatus for three-dimensional measurement of geometric parameters of a rope has a frame defining and arranged around a rope receiving cavity. Image acquisition devices acquiring digital images of regions of an outer surface of the rope are fixed to the frame and arranged around the rope when the calibrated three-dimensional optical measuring apparatus receives the rope in the rope receiving cavity. An electronic digital image processing device processes a multiplicity of digital images and obtains a three-dimensional photogrammetric reconstruction of points of the digital images of the rope. Having defined a circumferential direction running around a main extension axis of the rope and lying on a plane incident or perpendicular to the main extension axis of the rope, the image acquisition devices are arranged on the frame circumferentially spaced apart from one another along the circumferential direction. A lighting device is arranged along the circumferential direction between a pair of adjacent image acquisition devices.
