Abstract
A camera arrangement comprising a plurality of camera elements and a corresponding method of arranging camera elements is described. The camera arrangement improves the resolution of a stitched image by maintaining a uniform overlap between the fields of view of adjacent camera element. The uniform overlap is achieved. This is because the amount of unnecessary overlap required to achieve the required degree of overlap is reduced.
Claims16
A camera arrangement, comprising:
- a plurality of substantially co-located camera elements, each camera element having a focal plane upon which a respective field of view is imparted for forming a stitched image from the respective fields of view;
- and
- a controller configured to generate pitch, yaw and roll parameters for each of said camera elements, wherein
- the field of view of one of said camera elements has an overlap with the field of view of an adjacent camera element which is adjacent to said one camera element,
- an area of the overlap is minimized based on a minimum dimension necessary for forming the stitched image to maximize an area of the stitched image, and
- after a pitch movement of the field of view of said one camera element, the positioning of said one camera element is such that said area of the overlap is minimized by rolling said one camera element, said adjacent camera element or both based on the roll parameters generated by said controller such that said overlap is substantially uniform along a length of the overlap.
A method of arranging a plurality of co-located camera elements, comprising:
- overlapping the field of view of one camera element with the field of view of at least one adjacent camera element to form an overlap, wherein the fields of view are movable and imparted onto a focal plane of said respective camera elements for forming a stitched image from the fields of view;
- and
- minimizing an area of the overlap based on a minimum dimension necessary for forming the stitched image to maximize an area of the stitched image by positioning, after a pitch movement of said field of view of said one camera element, said one camera element such that said overlap is minimized by rolling said one camera element, said adjacent camera element or both such that said overlap is substantially uniform along a length of the overlap.
A camera arrangement, comprising:
- a plurality of imaging means for capturing images, each imaging means having a focal plane upon which a respective field of view is imparted for forming a stitched image from the respective fields of view;
- and
- controlling means for generating pitch, yaw and roll parameters for each of said imaging means, wherein
- the field of view of one of said imaging means has an overlap with the field of view of an adjacent imaging means which is adjacent to said one imaging means, an area of the overlap is minimized based on a minimum dimension necessary for forming the stitched image to maximize an area of the stitched image, and
- after a pitch movement of the field of view of said one imaging means, the positioning of said one imaging means is such that said area of the overlap is minimized by rolling said one imaging means, said adjacent imaging means or both based on the roll parameters generated by said controlling means such that said overlap is substantially uniform along a length of the overlap.
