An electronic device includes a processor and a memory coupled to the processor. The memory includes a computer readable storage medium having computer readable program instructions stored therein that are executable by the processor to determine a position and/or orientation of sensor device that is arranged to capture data for a subject from the position and/or at the orientation, and, based on the position and/or orientation that was determined, control creation of a 3D representation of the subject from the data captured by the sensor device. Related methods and computer program products are also discussed.

Electronic devices, methods, and computer program products for controlling 3D modeling operations based on pose metrics

A method for estimating a 3D map is described. The method includes performing an initialization of a plurality of 3D points in the 3D map based on the plurality of 2D images, reprojecting ones of the 3D points onto ones of the 2D images to obtain reprojection points, determining respective reprojection errors of ones of the reprojection points, determining a robust camera parameter associated with a weighting function based on the respective reprojection errors, and performing bundle adjustment to update the 3D map and update the plurality of poses, based on the robust camera parameter and the weighting function. Related systems, devices and computer program products are also described.

Methods, devices and computer program products for global bundle adjustment of 3D images

A method for estimating a 3D map and a plurality of poses is described. The method includes non-recursively performing an initialization of the 3D map and the respective poses of the plurality of poses based on a plurality of first 2D images of the series of 2D images, and recursively performing sequential updating of the 3D map based on recursively updating the 3D map for respective ones of a plurality of second 2D images of the series of 2D images. Related systems, devices and computer program products are also described.
