Title: Methods and apparatuses for determining positions of multi-directional image capture apparatuses
Inventor: TINGHUAI WANG
IPC: G06T7/70
Filed: 2017-04-11
Abstract: Image re-projection is performed (S5.2) on each of a plurality of first (e.g. fish-eye) images of a scene, to generate a plurality of re-projected second (e.g. rectilinear) images of the scene, wherein each first image is captured (S5.1) by a respective camera of a multi-directional image capture apparatus and each second image of the scene is associated with a respective virtual camera. The second images are processed based on a previously generated virtual three dimensional (3D) model of the scene (e.g. using point correspondences and a Direct Linear Transform) to generate respective positions of the virtual cameras associated with the second images (S5.3). The multi-directional image capture apparatus position is determined (S5.5) based on the generated positions of the virtual cameras. Using computationally expensive Structure from Motion (SfM) processing to determine the position and/or orientation of a new and/or moved multi-directional image capture apparatus is avoided by instead using transformed captured images in conjunction with a previously generated virtual 3D scene model. The previously generated 3D model, which may have been generated using images previously captured on multi-directional image capture apparatuses, may be updated with the determined position of the multi-directional image capture apparatus.
