Abstract
A method for detecting the form of sails and the like wherein in the form detection is brought about by means of a three-dimensional measurement of a plurality of locations of the surface of the sail, which measurement is carried out by means of measurement of the time-of-flight of an optical signal.
Claims24
A method for detecting the form of a sail, comprising detecting the form of the sail by a three-dimensional measurement of a plurality of locations of a surface of the sail, which measurement is carried out by measurement of a time-of-flight of an optical signal,
- wherein the optical signal is used to generate a cloud of locations measured on the sail and the locations of the cloud of locations are then interpolated in order to generate a real surface of the sail during operation, and the real surface is compared with a theoretical design surface of the sail in order to adjust the sail via the comparison between the real surface and the theoretical design surface.
A method for detecting the form of a sail, comprising detecting the form of the sail by a three-dimensional measurement of a plurality of locations of a surface of the sail, which measurement is carried out by measurement of a time-of-flight of an optical signal,
- wherein the optical signal comprises a laser signal generated and received by means of a multi-echo time-of-flight (TOF) laser scanner, and the TOF laser scanner is controlled by a computer program which controls a motorization unit,
- and wherein an angle of rotation about an axis (15) is adjusted according to the dimensions of the sail and a position of the TOF laser scanner, and is such as to illuminate the entire surface of the sail over a time interval, starting from an initial scanning position that is determined, for each acquisition of data, by a proximity transducer (25) mounted on a bracket (14), and the proximity transducer is sensitive to an angular position of the scanner.
