Embodiment Construction

[0021] figure 1 A cross-section of an inspection device according to a first embodiment of the present invention is schematically shown.

[0022] exist figure 1 In , reference numeral 1 designates an inspection device for a camera 4 comprising optics 4a. The camera 4 is connected to an evaluation device 7 , 8 , wherein the evaluation device is designated with reference numeral 7 , which automatically evaluates the images recorded by the camera 4 . Reference sign 8 denotes a monitor on which the images of camera 4 are displayed and, if appropriate, the evaluation results of evaluation device 7 are displayed for the user. The camera 4 is arranged in a holding device 5 which is in particular arranged stationary relative to the light sources 2a-2e. The light sources 2a-2e are arranged at least partially circularly around the imaging optics 4a of the camera 4, so that they can emit light with their respective light L 2 , L 3 Load camera 4. Here, the light sources 2 a - 2 e ea...

Abstract

The invention relates to a checking apparatus for a camera, particularly from driver assistance systems in a motor vehicle, comprising a mount for a camera for at least two light sources for emitting test light to the camera, wherein the mount and at least one of the at least two light sources are arranged so that their relative situation and position are fixed in relation to one another, and a control device which is designed to operate the at least two light sources such that, in each case in chronological order, one light source is on and the at least one further light source is off. The invention likewise relates to a checking method for a camera and to a checking system.

Description

technical field [0001] The invention relates to an inspection device for a video camera and a method for inspecting a video camera. The invention likewise relates to the use of the inspection device and the inspection system. Background technique [0002] Video cameras are used in various ways in the prior art, among them also in automotive technology. The camera can be used, for example together with a driver assistance system, to observe the traffic space ahead of the motor vehicle. The camera has a high dynamics and an associated large brightness range in order to be able to record in the desired quality both during the day and at night. Due to the large brightness range, the camera is sensitive to imperfections in the optics which cause disturbing or scattered light. Optical imperfections can be caused by reflections from the bezel, errors in lens compensation, particles or scratches. Interference or scattered light can then be seen as artifacts in the image area of ...
