Abstract
A technique for generating a three-dimensional reconstruction of a scene involves generating a high-fidelity point cloud representing a three-dimensional reconstruction of a scene from two-dimensional images generated by at least one sensor whose position and orientation are known relative to a fixed coordinate system for each of the images. The high-fidelity point cloud is generated in a relative coordinate system without regard to the position and orientation of the sensor(s). A low-fidelity point cloud is generated in the fixed coordinate system from the two-dimensional images using the position and orientation of the sensor(s) relative to the fixed coordinate system. A transformation between the relative and fixed coordinate systems is determined based on a relationship between points in the high-fidelity and low-fidelity point clouds, and the high-fidelity point cloud is converted from the relative coordinate system to the fixed coordinate system by applying the transformation to the high-fidelity point cloud.
