Abstract
A surround-view imaging system for 3D imaging of a surrounding of the system which avoid saturation and overexposure of an associated image detector, comprising an imager and an illuminator. The illuminator and the imager are arranged one over another and separated from one another by a distance to form an intermediate region which is neither in the field of view of the illuminator nor in the field of view of the imager, and corresponding imager for such surround-view imaging system.
Claims6
An imager for a surround-view imaging system, comprising:
- an image detector and a cylindrically shaped monolithic catadioptric lens having a corpus with a mantle, a top surface and a bottom surface;
- wherein in a field of view of the imager, imaging light from a surrounding of the imager enters the corpus by the mantle, is firstly reflected by a circumferential first aspheric lens region arranged around a center of the bottom surface and formed as a Forbes asphere, is secondly reflected by a second aspheric lens region arranged at a center of the top surface, and leaves the corpus towards the image detector by a third aspheric lens region at the center of the bottom surface.
A surround-view imaging system for imaging a surrounding of the system, comprising:
- an imager and an illuminator;
- wherein the illuminator is adapted to illuminate in a field of view of the illuminator the surrounding of the system such that illumination light that is reflected by the surrounding can be imaged by the imager in a field of view of the imager as imaging light;
- wherein the illuminator and the imager are arranged one over another and separated from one another by a distance d to form an intermediate region which is neither in the field of view of the illuminator nor in the field of view of the imager;
- and
- wherein the field of view of the illuminator simultaneously comprises a primary illumination region with high maximum illumination power and a secondary illumination region arranged between the primary illumination region and the imager with lower maximum illumination power.
A surround-view imaging system for imaging a surrounding of the system, comprising:
- an imager having an image detector and a detection controller, and an illuminator;
- wherein the illuminator is adapted to illuminate in a field of view of the illuminator the surrounding of the system such that illumination light that is reflected by the surrounding can be imaged by the imager in a field of view of the imager as imaging light;
- wherein the detection controller increases frame rates of the image detector by limiting a readout of the image detector to a region of interest;
- and
- wherein a definition of the region of interest is based on a prospected motion profile of the system.
