Abstract
A method and a device for the detection of obstruction in image sensor systems made up of at least two image sensors, which record essentially the same scene. If at least one image feature of the respective images differs unacceptably between the respective images, a signal is generated indicating the obstruction.
Claims10
A method for the detection of an obstruction in an image sensor system, comprising:
- providing at least two image sensors, the at least two image sensors recording essentially the same scene;
- and
- generating a signal indicating an obstruction of at least one of the image sensors if images generated by the image sensors deviate unacceptably from one another in at least one feature.
A device for the detection of an obstruction in an image sensor system having at least two image sensors which record essentially the same scene, the device comprising:
- an evaluation unit for evaluating images generated by the image sensors and for generating a signal if at least one feature deviates unacceptably in the images of the image sensors.
