Camera arrangement with illuminator
A camera arrangement comprising a camera head, an illumination arrangement, and a dome. The camera head is arranged inside the dome, and the illumination arrangement is arranged on an outside of the dome.
1. A camera arrangement comprising:
a camera head;
an illumination arrangement; and
a dome, wherein:
the camera head is arranged inside the dome;
the illumination arrangement is arranged on an outside of the dome;
the dome has a toroidal shape with a rotational symmetry along a rotational angle around a first axis of symmetry;
at least an outer segment of the dome is transparent;
the outer segment has a shape in section which is defined by a second axis of symmetry arranged at a first radius from the first axis of symmetry and orthogonal to the first axis, the outer segment having a radius of curvature over an angle around the second axis of symmetry;
the dome further comprises a central segment connecting the outer segment with the first axis of symmetry; and
the illumination arrangement is arranged at the central segment.
2. The camera arrangement according to claim 1 , comprising a plurality of camera heads, the camera heads being arranged inside the dome.
3. The camera arrangement according to claim 1 , wherein the angle over which the outer segment is curved is less than or equal to 90°, and wherein a transition from the outer segment to the central segment is rounded.
4. The camera arrangement according to claim 1 , wherein the illumination arrangement comprises a circumferential wall arranged to prevent light from the illumination arrangement from entering the dome.
5. The camera arrangement according to claim 1 , wherein the illumination arrangement comprises an IR illuminator.
6. The camera arrangement according to claim 5 , wherein the IR illuminator is arranged to emit IR light in a spectral range of 730-1000 nm.
7. The camera arrangement according to claim 5 , wherein the IR illuminator comprises a plurality of IR LEDs.
8. The camera arrangement according to claim 7 , wherein the IR illuminator is arranged to emit IR light in a spectral range of 730-1000 nm.
9. The camera arrangement according to claim 1 , wherein the illumination arrangement comprises wiring passing through the central segment to an electronics unit of the camera arrangement.
