DEVICE, METHOD AND SYSTEM FOR RECONSTRUCTING 3D-MODEL OF OBJECT Russian patent published in 2018 - IPC G01V3/18 

FIELD: physics.

SUBSTANCE: invention is aimed at a device, method, and system for the 3D-reconstruction of an object from images generated by scanning an object on 360°. The claimed group of the inventions includes a device for reconstructing the 3D-model of the object, a method for reconstructing the 3D-model of the object, and a system for reconstructing the 3D-model of the object. Moreover, the device for reconstructing the 3D-model of the object includes: a scanning module configured for scanning an object along a trajectory around the object and capturing images of the object from different points on this trajectory, a memory block configured to save the captured images of the object, at least one processor configured to implement the 3D-reconstruction using the saved captured images for the formation of the 3D-model of the object, and a mapping module configured to display the 3D-model of the object. The said at least one processor configured to implement the process of the 3D-reconstruction by: evaluating when scanning the object of the scan object location corresponding to each of the captured images, transmitting the estimated scan module location to the memory block for their storage, refinement, after completion of the object scanning, the estimated scan module location stored in the memory block, using information about the primary and end points of the trajectory, and transmitting the refined scan module locations to the memory block for their storage, construction of the depth map corresponding to each of the specified scan module locations and each of the captured images, combining all depth maps to generate a 3D-representation of the object, creating a surface mesh of the object based on the 3D-representation, overlaying the coloured textures on the surface mesh of the object to reconstruct the 3D-model of the object and to transmit the 3D-model of the object to the memory block for its storage.

EFFECT: providing the possibility of quick creating a high-quality 3D-model of the object in the conditions of rigid restrictions both to the size of the data storage and to the computational cost, ie using less time and computational cost than the analogues from the prior art, and without the use of additional expensive hardware.
