Method and device for three-dimensional reconstruction

A method for measurement, comprising:

• obtaining a three-dimensional model of a measured object;
• fitting a pre-stored measured three-dimensional model to the three-dimensional model of the measured object;
• and
• measuring the three-dimensional model of the measured object according to the pre-stored measured three-dimensional model and the fitting.

A device for three-dimensional reconstruction, characterized by comprising:

• an obtaining module, configured to obtain:
• a first depth map, which is photographed by a first photographic device;
• and
• a second depth map, which is photographed by a second photographic device;
• and
• a calculation module, configured to:
• merge the first depth map with a first three-dimensional model according to a position of the first photographic device to obtain a second three-dimensional model;
• and
• merge the second depth map with the second three-dimensional model according to a position of the second photographic device to obtain a third three-dimensional model.
