Document Type and Number:
WIPO Patent Application WO/2019/107679
Kind Code:
A1
Abstract:
The present invention relates to a multi-type sensor calibration system and a multi-type sensor calibration method, the multi-type sensor calibration system comprising: a color pattern plate having a lattice pattern formed on a surface thereof, the lattice pattern comprising black quadrangles having a predetermined size and white quadrangles having a predetermined size formed alternately; a heating-wire plate having a checkerboard pattern formed thereon and having a heating wire formed on a corner part of the checkerboard pattern; an imaging sensor portion for obtaining images of the color pattern plate and the heating-wire plate; a depth pattern plate having a predetermined depth and having a quadrangular pattern formed thereon, the quadrangular pattern comprising at least one quadrangle having a predetermined size formed thereon; a depth sensor portion for obtaining an image of the depth pattern plate; and a calibration portion for calibrating image information obtained by the imaging sensor portion so as to generate calibrated image information, for calibrating image information obtained by the depth sensor portion so as to generate depth calibration information, and for integrating the depth calibration information and the calibrated image information so as to generate final image information.
