Camera system and method for generating a combined image projection

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.

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.
