Abstract

Claims (65)

1 . A method of generating a combined image projection, comprising:

capturing a first image of an object by a first camera;

capturing a second image of the object by a second camera;

generating a first image projection of the first image;

generating a second image projection of the second image;

finding an image content of the first and second image projection being contained in both image projections;

overlapping the first and second image projections wherein the image content contained in both image projections matches together in an overlapped area;

determining a resolution value for each of two overlapping pixels of the overlapped area;

combining the first and the second image projection to a combined image projection; and

determining pixels in the first or second image representing a projection surface,

wherein the pixel of the two overlapping pixels having the higher resolution value is included in the combined image projection, and

wherein the pixels representing the projection surface are determined based on depth information of the pixels.

2 . The method of claim 1 , wherein the first or the second image projection is a planar projection.

3 . The method of claim 1 , further comprising:

determining pixels in the first or second image representing a projection surface.

4 . The method of claim 3 , further comprising:

determining distances of first and second camera to the projection surface.

5 . The method of claim 3 , further comprising:

determining an orientation of the projection surface based on an orientation of the first and/or second camera.

6 . The method of claim 1 , further comprising:

orienting the first and second image projections to bring the image content contained in the first image projection into alignment with the image content contained in the second image projection.

7 . The method of claim 1 , wherein the first image or the second image is an equidistant image.

8 . The method of claim 1 , wherein the image content contained in both image projections comprises at least two pixels.

9 . The method of claim 1 , wherein the image content contained in both image projections comprises the object; wherein the object is a reference marker for overlapping the first and second image projections.

10 . The method of claim 1 , further comprising:

determining a first distribution of resolution values of the first image projection within the overlapped area; and

determining a second distribution of resolution values of the second image projection within the overlapped area.

11 . The method of claim 10 , further comprising:

comparing the first and the second distribution of resolution values.

12 . The method of claim 10 , further comprising:

recognizing a change of the first or second distribution of resolution values.

13 . The method of claim 1 , further comprising:

determining a movement of the first or second camera.

14 . A method of generating a combined image projection, comprising:

capturing a first image of an object by a first camera;

capturing a second image of the object by a second camera;

generating a first image projection of the first image;

generating a second image projection of the second image;

finding an image content of the first and second image projection being contained in both image projections;

overlapping the first and second image projections wherein the image content contained in both image projections matches together in an overlapped area;

determining a resolution value for each of two overlapping pixels of the overlapped area;

combining the first and the second image projection to a combined image projection; and

determining pixels in the first or second image representing a projection surface,

wherein the pixel of the two overlapping pixels having the higher resolution value is included in the combined image projection, and

wherein the pixels representing the projection surface are determined based on color information of the pixels.

15 . A camera system for generating a combined image projection, comprising

a first camera;

a second camera; and

a control unit connected with the first and the second camera; wherein the control unit is configured to:

capture a first image of an object by a first camera;

capture a second image of the object by a second camera;

generate a first image projection of the first image;

generate a second image projection of the second image;

find an image content of the first and second image projection being contained in both image projections;

overlap the first and second image projections wherein the image content contained in both image projections matches together in an overlapped area;

determine a resolution value for each of two overlapping pixels of the overlapped area;

combine the first and the second image projection to a combined image projection;

determining a first distribution of resolution values of the first image projection within the overlapped area;

determining a second distribution of resolution values of the second image projection within the overlapped area; and

comparing the first and the second distribution of resolution values,

wherein the pixel of the two overlapping pixels having the higher resolution value is included in the combined image projection.

16 . The camera system of claim 15 , wherein the first camera comprises a fisheye lens or a rectilinear lens.

17 . The camera system of claim 15 , wherein the first camera and the second camera are of the same type.

18 . The camera system of claim 15 , wherein the first camera is relatively moveable in respect of the second camera.

19 . The camera system of claim 15 , comprising a reference marker.
