Panoramic 3D camera
A three dimensional imaging system for generating a 3D panoramic video/image is disclosed. The three dimensional imaging system comprising a plurality of stereoscopic pairs of compound cameras is disclosed. The pair of compound cameras being separated by a predefined distance d.
1. A three-dimensional imaging system comprising:
a plurality of stereoscopic pairs of compound imagers each having an overlapping panoramic field of view, wherein
each of the pair of compound imagers are separated by a predefined distance d, and wherein the imaging system is configured to:
operate in a first mode to generate plurality of panoramic images simultaneously by each of the compound imagers;
calculate a spatial distortion and a temporal distortion for each column in a region of overlap corresponding to the overlapping panoramic field of view of the panoramic images;
mark the column for which the calculated spatial distortion and the temporal distortion is minimum as a seam location; and
changing the location of seam based on detection of a face in the column for which the calculated spatial distortion and the temporal distortion is minimum.
2. The three-dimensional imaging system according to claim 1 , wherein each compound imager comprises a camera array assembly.
3. The three-dimensional imaging system according to claim 2 , wherein the camera array assembly comprise a plurality of camera sensors arranged along a convex axis.
