Detection system and a vehicle therewith

A detection system for vehicles adapted to record objects within a scenery at least in problematic viewing conditions, comprising:

• a camera system establishing an optical path from a light entrance aperture via a lens system to an image recording unit with the image recording unit being adapted to record visible and IR light one or more of reflected or emitted from the scenery comprising at least one object;
• an IR filter arranged within the optical path to block at least a first part of the IR light not being the at least one object related from reaching the image recording unit and
• a conversion filter arranged within the optical path to convert at least a second part of the IR light being the at least one object related to visible light of an image enhancing wavelength range,
• wherein the lens system comprises at least one lens arranged in front of the image recording unit to guide the light from the scenery through the IR and conversion filters to the image recording unit;
• wherein the visible light is divided into a first, a second and a third wavelength range, and the image recording unit comprises at least three segments, with a first segment being adapted to record only the first wavelength range of the visible light, a second segment being adapted to record only the second wavelength range of the visible light, and the third segment being adapted to record all wavelength ranges of the visible light, with the image enhancing wavelength range being within the third wavelength range, and
• wherein the image recording unit is adapted to record the first wavelength range of the visible light of the first segment and the second wavelength range of the visible light with the second segment, and
• a sum of the wavelength ranges including the first and second wavelength ranges and additionally the third wavelength range with at least the third segment, with a difference between the intensities of the third segment minus the intensities of the first and second segment resulting in intensity of visible light in the third wavelength range in the off-state of the conversion filter or in the sum of the intensities of the third wavelength range provided by the object and provided by the conversion filter.

• and
• an image matching unit adapted to compare the images recorded in an on state of the conversion filter with images recorded in an off state of the conversion filter, with critical objects being distinguished from non-critical objects or identified by comparing a contrast between both images, with objects moving relative to a moving direction of the vehicle showing less contrast in the image with the off state of the conversion filter when being compared;
• wherein the lens system comprises at least one lens arranged in front of the image recording unit to guide the light from the scenery through the IR and conversion filters to the image recording unit.
