Abstract
An image stitching method using viewpoint transformation and a system therefor are provided. The method includes obtaining images captured by a plurality of cameras included in the camera system, performing viewpoint transformation for each of the images using a depth map for the images, and stitching the images, the viewpoint transformation of which is performed.
Claims12
An image stitching method using viewpoint transformation executed by a computer included in a camera system, the method comprising:
- obtaining images captured by a plurality of cameras included in the camera system;
- performing viewpoint transformation for each of the images using a depth map for the images;
- and
- stitching the images, the viewpoint transformation of which is performed.
An image stitching system using viewpoint transformation, implemented with a computer included in a camera system, the system comprising:
- at least one processor configured to execute computer-readable instructions,
- wherein the at least one processor comprises:
- an image obtaining unit configured to obtain images captured by a plurality of cameras included in the camera system;
- a viewpoint transformation performing unit configured to perform viewpoint transformation for each of the images using a depth map for the images;
- and
- a stitching unit configured to stitch the images, the viewpoint transformation of which is performed.
An image viewpoint transformation method executed by a computer included in a camera system, the method comprising:
- obtaining an image captured by the camera system;
- setting a viewpoint transformation formula based on a focal length of the camera system, a length of a baseline of the camera system, and parallax of the camera system, based on a depth map for the image;
- determining a movement parameter in the viewpoint transformation formula, the movement parameter being a value associated with a distance to move when a location where the image is captured moves to a virtual specific location;
- and
- transforming a viewpoint of the image using the viewpoint transformation formula.
