Method and device for forming a panoramic image
First Claim
Patent Images
1. A method of forming a panoramic image by assembling images according to at least two non-parallel directions, the method being performed by an image processing device, and the method comprising the following steps of:
- storing first coordinates defining in a two dimensional space, edges of a current panoramic image,superimposing a current image on said current panoramic image for completing the current panoramic image, the current image thus having a first area which is not common with the current panoramic area,storing second coordinates defining in the two dimensional space, edges of the current image superimposed on the current panoramic image,deciding whether the first area should be added to the current panoramic image, based on the first and second stored coordinates, andadding, at least partially, the first area of the current image in the current panoramic image, if it has been decided to add the first area.

Abstract
There is described a method and a device for forming a panoramic image wherein it is decided to add a current image in a current panoramic image based on definitions of edges of the current image and the current panoramic image.

12. A circuit configured to form a panoramic image by assembling images according to at least two non-parallel directions by:
-
storing first coordinates defining in a two dimensional space, edges of a current panoramic image, superimposing a current image on said current panoramic image for completing the current panoramic image, the current image thus having a first area which is not common with the current panoramic area, storing second coordinates defining in the two dimensional space, edges of the current image superimposed on the current panoramic image, deciding whether the first area should be added to the current panoramic image, based on the first and second stored coordinates, and adding, at least partially, the first area of the current image in the current panoramic image, if it has been decided to add the first area. - View Dependent Claims (13, 14, 15, 16, 17)

18. A method of forming a panoramic image by assembling images according to at least two non-parallel directions, the method being performed by an image processing device, and the method comprising the following steps of:
-
storing first coordinates defining in a two dimensional space, edges of a current panoramic image aggregated from multiple previous images, superimposing a current image on said current panoramic image for completing the current panoramic image, the current image thus having a first area which is not common with the current panoramic image and a second area common with the current panoramic image, storing second coordinates defining in the two dimensional space, edges of the current image superimposed on the current panoramic image, deciding whether the first area which is not common with the current panoramic image should be added to the current panoramic image, based on the first and second stored coordinates, adding, at least partially, the first area which is not common with the current panoramic image to the current panoramic image, if it has been decided to add the first area, defining a third area in the current image, said third area being included in the second area in a vicinity of the first area and extending along a line of separation of the first and second areas, if it has been decided to add the first area, and performing a blending of pixels of the current panoramic image comprised in an area of the current panoramic image on which the third area is superimposed with the pixels of the current image comprised in the third area.
