Patent Searching and Data


Title:
IMAGE PROCESSING DEVICE, CALIBRATION BOARD, AND METHOD OF GENERATING 3D MODEL DATA
Document Type and Number:
WIPO Patent Application WO/2021/210403
Kind Code:
A1
Abstract:
The present technology pertains to an image processing device, a calibration board, and a method of generating 3D model data, for facilitating synchronization between devices. This image processing device is provided with: an image synchronization unit that time-synchronizes a plurality of images, on the basis of lit states of a plurality of light-emitting units included in the plurality of images which were obtained by a plurality of imaging devices each having imaged a board comprising the plurality of light-emitting units and a predetermined image pattern; and a calibration processing unit for using the time-synchronized plurality of images to calculate a camera parameter of the plurality of imaging devices. The present technology can be applied, for example, to image processing systems that perform imaging for generating 3D models.
