Abstract:
1. A system for monitoring surroundings of a vehicle, comprising: at least two optical sensors configured to detect characteristics of the surroundings of the vehicle, the sensors configured to operate in a wide-angle range, wherein each optical sensor includes a sensor lens system having at least one lens that detects characteristics of the surroundings of the vehicle; an arrangement for producing light in the infrared spectral range, the light being emitted to the surroundings of the vehicle via the at least one lens of the sensor lens system of each optical sensor; an arrangement for processing the detected characteristics and delivering spatial information based on the detected characteristics; and an imager chip which is sensitive in a near infrared spectral range; wherein at least one of the optical sensors includes one of a parabolic lens system or a parabolic mirror lens system for detecting a visual angle of 360°, the one of the parabolic lens system or the parabolic mirror lens system produces an approximately annular image on the imager chip in an illuminated region of the imager chip and a remaining region of the imager chip on which the approximately annular image is not formed is used for evaluation logic.
